404/408D
The Model 404/408D Loop to Switch Converter converts 4-20mA or 0-15psi inputs to control of up to 8 optically isolated 4-20mA outputs.It can be used for a variety or applications where control from a 4-20mA input is useful, or for pumping applications with either 4-20mA or 0-15psi inputs.For non-pumping applications, this allows control of up to 8 devices from a single 4-20mA source, with LCD monitoring of current level and individual status LEDs for which outputs are active. For pumping applications, the 404/408D contains an air pressure-to-voltage transducer and requires only a small air compressor capable of 15 psi to operate the system down to approximately 35 feet, with LCD display that shows liquid depth in feet.
The Model 404/408Ds eight outputs are designed to replace the float switch inputs to a Model 403 or model 407, or to be used with a Model 448 output Relay Board. A 4-20mA signal output provides for other control applications. A 3-digit LED display continuously shows the current level (mA), liquid level (to a tenth of a foot), or both. LED indicators illuminate as the levels are exceeded.

407D
The Model 407D 3-Pump Liquid Level Controller provides central operating control of triplex pumping systems. The solid-state electronic controller provides alternating of load pumps, low level cutoff and high level alarm outputs. Runtime meters provide instant visual data on total running time of each pump motor. LED indicators show ON/OFF status of each pump. The 407D has five level-sense inputs which can be activated by float switches or other level sensing devices which provide a switch closure. -
403D
The 403D Liquid Level Controller provides central control of duplex pumping systems. The Model 403D includes pump alternating, visual run-time meters, hand-off-auto control and alarm outputs. Four level-sense inputs interface with float switches, pressure switches, or other level sensing devices which can provide a contact closure. -
TMC430
The Time Mark model 430 pump controller is a versatile and advanced liquid level/pump management system. The Model 430 was designed to control up to three pumps with a 4-20mA input. It can also be used to control 2 pumps with a 4-20mA input and backup floats or to simply control two pumps with only float inputs. Alarm inputs are provided, if necessary, and may be disabled through the menu system if not used. Alarm inputs are: SF – seal fail, OT – over temperature, CF – contact failure, and SP – spare (eg. a second seal fail). A relay output is provided for the level alarm (either high or low), depending on pump configuration; PUMP UP or PUMP DOWN.(Custom keypad and firmware with logo splash screen are available.)

460D
Liquid level controllers generally require a 4-20mA loop current. The loop current indicates the level of liquid in a tank or reservoir, and is usually generated by an expensive pressure transducer or ultrasonic sensor. If you already have a tank with float switches installed, the Model 460D Switch-to-Loop Converter allows you to take advantage of the latest liquid level control, without the added cost of a transducer.
The Model 460D Converter outputs a specific current value as each of the six inputs are closed. Current values are individually adjustable between 4 and 20mA for each switch input. Up to six switches can be used as inputs to all liquid level devices accepting a 4-20mA input, such as Time MarkÕs Model 4052. -
456-15
***DISCONTINUED FROM TIME MARK***
The Model 456-15 Pressure Transducer is designed specifically to meet the rigorous environments encountered in many level measurement applications. This transducer provides repeatable, precise depth measurements under the most adverse conditions.It has been designed for installation in Class 1, Division 1, Groups A,B,C and D; Class II, Division 1, Groups E,F and G; Class III, Division 1 hazardous locations, when connected to the appropriate Stahl apparatus.
The Model 456-15 features high performance internal signal conditioning. An isolated diaphragm sensor has been incorporated for use with hostile fluids and gases. This sensor uses a silicon pressure cell that is fitted into a stainless steel housing with an integral, compliant stainless steel barrier diaphragm. The sensor assembly is housed in a rugged, compact 316 SS case, which provides for a variety of pressure inputs as well as electrical output connections.
This item is no longer sold by Time Mark (though it is still in production with the original manufacturer.)

409D-24
The Model 409D is a compact, socket-mount device for level control of conductive liquids. The internal relay is energized when operating power is applied. When the liquid level reaches the probe, the relay de-energizes. When the level drops below the probe, the relay will reset. A fixed, 300ms time delay prevents oscillation due to wave action. Probe cables may be shielded or unshielded. If the liquid container is made of a non-conductive material, a common electrode is required. Other features include an LED indicator to show the output relay status and an adjustable sensitivity setting. Requires a standard 11-pin octal socket (such as the Time Mark model 51X016). -

4092I-120
The Model 4092I Isolated Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. All electrical inputs are totally isolated from each other. The probes are to be installed in the seal cavities of each of the pumps. The sensitivity is field adjustable. When a seal begins to leak, contaminating fluid enters the seal cavity, lowering the resistance between the probe and the common connection. If the resistance drops below the sensitivity set-point, the corresponding relay and the LED indicator are activated. The Model 4092I will automatically reset when the fault condition is corrected.Also available in a 240 VAC version, ask for details.

4093-240
The Model 4093 is a compact, socket mounted Liquid Level Controller that operates by monitoring the conductive liquid resistance between two probes. The unit monitors two liquid levels and responds as a pump-up or pump-down control as determined by the switch setting on the top of the unit. The green LED indicates pump operation while the potentiometer allows the user to adjust probe sensitivity. -

4082
The Model 4082 Liquid Level Controller monitors, displays and controls water level up to 34.6 feet in a tank or reservoir. The Model 4082 operates from the 4-20mA input signal provided by either the Time Mark Model 450 or Model 456-15 Pressure Transducer. This 4-20mA signal represents the water level to be controlled, where 4mA equals zero feet, and the 20mA equals 34.6 feet. A liquid crystal display (LCD) is provided to show the water level during normal operations, and the set-point values during calibration. There are eight user-adjustable trip set-points. As the water level rises above each trip point setting, the front panel LED for that level illuminates, and the corresponding output relay energizes. Two 4-20mA outputs, which track the 4-20mA input, are also provided. These signal outputs can be rescaled to different ranges of level by the user. A test control, that simulates an input signal, is available on the front panel. The test control is useful for checking the trip set-points, and overall system operation. -
4062
The Model 4062 Pump-Up Controller provides total control for duplex pumping systems. The Model 4062 monitors, controls and displays the liquid level in a tank or reservoir, up to a depth of 34.6 feet. The input to the Model 4062 can be from any 2 or 3-wire transducer with a 4-20mA output that represents 0 to 34.6 feet. A 24VDC regulated probe supply is included. A Level Simulator is provided to aid in programming these five set points; Low Alarm, Level 2, Level 1, Pumps Off and High Alarm. A universal zero to 30 second On Delay can be programmed to prevent outputs from closing due to input fluctuations caused by turbulent conditions. An additional 4-20mA output with zero and span controls is provided for a chart recorder or other external device. Four heavy-duty 10 amp, 120V contacts are provided for pump control and alarm activation. An auto-dialer or other emergency device can be activated with the SPDT power loss relay. This relay is held open when power is applied. Communications capable via RS-485/Modbus. Pump outputs include duplex alternation as well as hand-off-auto switches. Pump run-time can be displayed for each pump with tenth of an hour resolution, up to 99,999. 9 hours. The Model 4062 can be panel-mounted (11 1/8 x 4 5/8), same as Time Mark Models 403, 404, 4042 and 4052, or surface-mounted using the optional surface-mounting kit, Model 4000.
