The TimeMark 660 is a 4-20 mA trip control for a 24 V DC ±5%, 30mA maximum supply. It watches a 4-20 mA loop and energizes a rising-trip or falling-trip relay outside its trip point.
Contacts: 2 x SPDT (rising trip, falling trip). Inputs: 4-20mA current loop; 50 ohm input. Input: 4-20 mA; 50 ohm. Set points: trip: 4 - 20mA; dead band: 1 - 10%. Output: 10 A at 240 V AC resistive. Reset: automatic. Indicators: top-mounted LEDs: RISING TRIP, FALLING TRIP, INPUT LOOP ERROR. Life: 10,000,000 operations mechanical, 100,000 electrical.
Mounting: plug-in, on an 11-pin octal (TimeMark 51X016 socket) base. Dimensions: 3.52" x 1.75" x 2.44". It operates from -25 to +50 °C.
