850-24VDC
The Model 850 Two Hand Control Module is designed to be used with two palm or push-button switches, which must be closed within 0.5 seconds of each other to operate machinery. As long as both switches are pressed, the relay will remain energized in the continuous mode. For applications requiring a pulse to initiate operations, the Model 850 can be set to produce a pulse output by connecting a resistor to pins 4 and 7. The resistor value in ohms should be 100,000 times the desired time in seconds (R=100,000 x T). The internal relay de-energizes on completion of the pulse, even if both switches are depressed. The relay also will de-energize immediately, if either hand switch is released, in standard or pulsed mode. The compact size of the Two-Hand Control Module allows installation into an existing control panel. It can be used with any type of machinery requiring safe, two-handed operation such as presses, punches, cutters, etc. The standard nominal supply voltages are 120VAC, 240VAC, or 24VAC at 50/60 Hz. , or 24VDC. -

661
The Model 661 Alarm Control, part of the 600 series line of instrumentation controls, is designed to monitor and maintain measurable applications such as liquid levels, temperature, pressure, flow, etc. A user-provided 4-20mA current loop represents the measurable application, and output connections are provided for signal alarms. Two setpoints, the HIGH ADJUST, and the LOW ADJUST, are field adjustable. If the input is between the two setpoints, the relays are energized. If the input is above the high setpoint, the HIGH ALARM relay de-energizes to provide a tripped condition. This tripped condition will automatically reset when the input falls back below the setpoint. If the input falls below the low setpoint the LOW ALARM relay de-energizes. The tripped condition resets when the input rises back above the setpoint.The Model 661 is equipped with top-mounted LEDs for trip status indication. A HIGH ALARM or LOW ALARM LED turns OFF in a tripped condition. The 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 DC operating voltage. A Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal.

660
The Model 660 Trip Control, part of the 600 series line of instrumentation controls, is designed to monitor and maintain a set level on a measurable variable, such as liquid level, temperature, pressure, flow, etc. A user-provided 4-20mA current loop represents the measurable application. Two trip points, the rising setpoint, and the falling setpoint are field adjustable. They are set by calibrating the DEAD BAND and TRIP adjustments. If the input is between the two setpoints, the relays are de-energized. If the input goes above the rising setpoint, the RISING TRIP relay energizes to provide a tripped condition. This tripped condition will automatically reset when the input falls back below the setpoint. If the input falls below the falling setpoint the FALLING TRIP relay energizes to provide a tripped condition. The tripped condition resets when the input rises back above the setpoint. The Model 660 has top-mounted LEDs for status indication. Individual RISING TRIP or FALLING TRIP LEDs turn ON in a tripped condition. The 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 DC operating voltage. A Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal. -
650-120-24
The Model 650 Loop Power Supply provides DC power for instrumentation control modules. Each option provides three output selections. For example the Model 650-240-24 has output options of 24 VDC regulated, 32 VDC unregulated, and 60 Hz pulse at 46 peak volts (See datasheet for all output selections).All outputs for the Model 650 are floating, electrically isolated from ground. A power status indicator (LED) is located on the top of the unit. The POWER LED comes ON when power is applied.
Applications for this device include two-wire current loop transducers, such as pressure, voltage or current. The Model 650 may also be used with alarm indicators, meters and timers.

421
The Model 421 detects an overload or under-load condition on all types of running motors; conveyor motors, elevator motors, mixer motors, submersible pumps, suction pumps, etc. The monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors. The Model 421 can be used with single-phase motors, or using the Model 276C Current Transducer, with three-phase motors. Matching CTs allow the Model 421 to be used with virtually any size of motor. Trip and restart delays are provided; one or both can be turned on or off. -
412
The 412 Automatic Reverse Controller is a current sensor designed to detect jamming of sewage grinders and to initiate the reversing of the grinder. The controller allows the selection of up to five forward/reverse cycles, and provides for an alarm output, if the number of cycles is exceeded. The current loop inputs are designed for direct connection of 10 amps at 240 VAC, or 5 amps at 480 VAC (up to 2hp motors). For higher currents, a current transformer must be used (the CT secondaries are connected to the 5 amp terminals, regardless of voltage). A manual push-button is used to simulate an over current condition and to test the relay contacts and alarm. A current level adjustment is used to optimize the trip point setting. LED indicators show the running direction of the motor and the alarm condition. -
295-240
The Model 295 Capacitor Trip Device is used to trip circuit breakers requiring an AC voltage, by using the stored energy in a capacitor. The capacitor is kept at full charge during normal operation by a half-wave silicon rectifier which draws its energy from the power line. When completely discharged, the Model 295 draws approximately 10 amps from the line in the first half cycle, 3 amps the second half cycle and 1 amp from the third. Continuous current required to keep the capacitor charged is less than 5 milliamps. The capacitor holds sufficient charge to trip the breaker for at least 12 seconds after the charging voltage is removed. However, on most fault conditions, some voltage is still present, so the Model 295 is designed so that 65% of normal voltage gives sufficient charge to trip the breaker. A low-energy lamp, connected in parallel with the storage capacitor, gives a visual indication when the voltage charge is 85 volts or more on the 120V version and 170 volts or more on the 240V version. -

Time Mark’s Splash Pad Controller can sequence up to 12 channels (outputs) with one to four channels active at a time. The controller offers 2 modes of operation:
(1) Sequence Mode: Once triggered, the unit will activate up to four outputs for a predetermined time, deactivate those outputs and then repeat with the next outputs in sequence.
(2) Random Mode: Once triggered, the unit will activate up to four random outputs for a random amount of time (120 to 300 sec.). After that, the unit will deactivate those outputs (1 to 30 sec.), then pick a new set of outputs.
In either mode: you can adjust the total run time, the number of outputs (up to four), the length of time they stay on and the length of time before the next group of outputs come on.Optional custom programming is available.
