Model 27 has a rotary encoder with switch on the unit. By pressing the encoder switch for more than 5 seconds, the unit will enter the setup mode. This unit has a user selectable relay option for High-Low or DPDT. It can also be user-selected to energize on fault or de-energize on fault. The user can select automatic or manual restart on the Model 27. The SG version of the Model 27 has silver with gold flash contacts for low current applications. Model 27 True RMS Current Monitor can be either calibrated using a True RMS Multimeter or can be restored to factory defaults in the field. -

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. -
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.

662
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
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. -
D471
The Model 471 Multi-Stage Alternator is designed to control the operating sequence of multi-stage pumping systems. it can also be used to maintain the desired level of pressure on air compressor systems. Four PUMP SELECT DIP switches located on the front panel allow the alternator to control a single-pump, two-pump, three-pump or four-pump system. Only one switch needs to be set for the total number of pumps in the system. The Model 471 will assure that only the necessary pumps are operating, and that the run time for each pump is approximately equal. Pumps are sequenced first-on and first-off. If the pumping demand requires only one pump at a time, the alternator will start the next pump in sequence each time an input switch is closed. Input switches may be float switches, pressure switches, flow switches, etc. , as required by the application.Potential uses for the Model 471 include water supply systems, sewage disposal plant systems, storage tank filling systems, air compressor systems, irrigation and water recycling systems.

DC260B-20-24
The Model 260 Voltage Sensor is a single set-point voltage sensor. Input voltages above the set-point cause the output contacts to energize (contacts 1 & 8 closed). Input voltages below the set-point cause the output contacts to de-energize (contacts 1 & 2 closed). The dead band between pull-in and drop-out is less than 2%.The standard unit has a screwdriver, or fingertip adjustable set-point range of approximately 35%. of the maximum voltage. This device can also be provided with a factory calibrated trip point.
AC versions of the Model 260 Voltage Sensor are not frequency sensitive, and may be used in systems from 50 Hz to 400 Hz. DC models are not polarity sensitive. This device requires a standard 8-pin socket, such as Time Mark’s Model 51×120.
