  4092I-120

  Isolated Dual Seal Failure Detector
  Read more
  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.

  409D-120

  Liquid Level Controller
  11-Pin, DPDT
  Read more
  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).

  422

  Submersible Pump Controller
  Read more
  The Model 422 Submersible Pump Controller detects an overload or underload condition on all types of running pump motors: suction pumps, submersible pumps, etc. This Monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors. The 422 can be used with single phase pumps or, using the Model 276C current transducer, with 3-phase pumps. Matching CTs allow the Model 422 to be used with most pump motor sizes. Optional trip and restart delays are provided.

  448

  Output Relay Board
  Read more
  The Model 448 Output Relay Board provides electromechanical relay contacts for the Model 404 or 408 Liquid Level Sensors, allowing those models to be used as a control device. The Model 448 consists of a power supply and five relays on the surface-mounted printed circuit board. Four of the five relays are used with the Model 404. All five relays are used on the Model 408, refer to typical application. Some liquid level control applications may not require the alternating control, HOA switches, or run-time meters (see the Model 403 or Model 407 data sheets). The Model 404 and Model 408 Liquid Level Sensors uses the Model 448 to meet the needs of direct relay control applications.

  460D

  Switch-to-Loop Converter
  4-20mA loop output
  Read more
  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.

  662

  Pump Up Control
  Read more
  The Model 662 Pump Up Control, part of the 600 series line of instrumentation controls, is designed to monitor andmaintain liquid levels. A user-provided 4-20mA current loop represents the liquid level, and output connections are provided for pump control. The HIGH ADJUSTsetpoint, and the LOW ADJUST setpoint, are field adjustable. If the input falls below the low setpoint, the PUMP UP relay energizes, and remains that way until the input rises above the high setpoint. The high setpoint must always be set above the low setpoint. Top-mounted LEDs on the Model 662 show system status. The PUMP UP LED turns ON when the input falls to 10% below the low setpoint, and resets when the input rises above this level. An INPUT LOOP ERROR LED turns ON if the input is outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or equivalent) is required to provide the 24 VDC operating voltage.

  A Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal.

  663

  Pump Down Control
  Read more
  The Model 663 Pump Down Control, part of the 600 series line of instrumentation controls, is designed to monitor and maintain liquid levels. A user-provided 4-20mA current loop represents the liquid level. The HIGH ADJUST setpoint, and the LOW ADJUST setpoint, are field adjustable. If the input rises above the high setpoint, the PUMP DOWN relay energizes, and remains that way until the input falls below the low set point. Top-mounted LEDs on the Model 663 show system status. The PUMP DOWN LED turns ON when the input is above the high setpoint, and goes OFF when the input is below the low setpoint. The HIGH ALARM condition indicator turns ON if the input rises to 10% above the high setpoint. The HIGH ALARM condition then resets when the input is again less than 10% above the high setpoint. For proper operation, the high setpoint must always be set above the low setpoint. An INPUT LOOP ERROR LED turns ON if the input is outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or equivalent) is required to provide the 24 VDC operating voltage. Also, a Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal.

  680

  Voltage/Current Simulator
  Read more
  The Model 680 is a user selectable voltage or current simulator. It is useful for the setup and testing of process controllers and indicators with either a current loop or control voltage input, such as liquid level controllers and other devices. The mode of operation is displayed on the top line of the LCD. Either 4-20mA, 0-20mA, 0-10V, or 0-5V. The Model 680 can be set to any one of these four modes of operation by holding down the rotary push-button until the desired mode is displayed. The mode is saved in nonvolatile memory so that the device will power up in the mode last selected. The output signal level is displayed on the bottom line of the LCD. On power up or on changing the mode of operation, the output goes to the range minimum, i. e. 4mA, 0mA, or 0V. The Model 680 offers short circuit protection by actively sensing for any overload condition and limiting output current to 20mA. Overload at the output is indicated by OL on the top line of the LCD and occurs when the output current is 21mA or greater. Signal level is adjustable with the rotary dial in increments of 0.1mA or 0.1V, or you can depress the dial to quickly jump between the minimum and maximum values of the range.
