CRD-020 Programmable Setpoint Relay, Protection relay, Trip Relay


FEATURES Programmable set-point relay setting for input current, threshold levels, over and under-current operation. Internal DIP-switches may be set for either 0-1mAdc or 0-10Vdc, and may be set for under-alarm or over-alarm relay operation. Internal DIP-switch to set the current ranges of either 0-5, 0-10, 0-15, or 0-20 Amperes, and the relay mode for under- or over-current operation. Lid-mounted two-digit numerical push-button switch calibrated as percent of full scale with a threshold range of 1-99%. Red LED lamp lights to indicate when the threshold level has been obtained

Highlighted area indicates Factory Setting. Unit is shipped from the factory with a 0-5 Amp input and in an over-current relay mode. The set point relay can be set to provide any one of the four current ranges and modes of operation. * The output relay will energize when instrument power is applied and the current is above the set point threshold. It will remain in a "Fail Safe" mode until either the input current drops below the set point threshold or instrument power is removed	** The output relay will energize when instrument power is applied and will remain in a "Fail Safe" mode until either the instrument power is removed or the input current exceeds the set point threshold level.
