1310 Series DC Voltage Level Sensor, Relay Output Product Facts ■ ■ ■ Standard models combine DC voltage-sensing circuit with 2A DPDT output relay. Various applications ■ Battery protection ■ Computer protection ■ Low or high voltage alarms Many customizing options ■ Solid state output ■ Two-stage sensing (voltage band) ■ Up to 10A relay output ■ Controlled dropout differential ■ Operate with auxiliary control voltage ■ Time delay on trip point ■ Tighter accuracy ■ Different package, mounting, header The CII 1310 series DC voltage sensor is essentially a voltage monitoring device operating a snap-action transistor circuit with low drift and inherent temperature compensation. This device will either open or close a circuit when a predetermined voltage is present at the input. By using a CII electromechanical relay as the output of the voltage sensor, a positive switching action can be achieved with very close differential between pull-in and drop-out voltages. The unit is potted and hermetically sealed and is designed to meet the environmental requirements of MIL-R-83726.
