CSDECMM-C50050 Johnson Controls Current Switch Datasheet

The fixed setpoint Current Switch Device for Electronically Commutated Motors (CSDECM) Series of Current Switch Devices feature a range of minimum turn-on options including 250 mA, 350 mA, and 500 mA. These options eliminate the possibility of a false reading. Even when idle, ECMs draw a small amount of current. Some fixed point sensors feature a minimum turn-on value within the vicinity of the ECM’s idle current, making them ineffective in distinguishing between on and off status.

CSDECM Current Switch Devices can also be used with other electrical loads when a simple sensor is needed.

The CSDSC and CSDECM Current Switch Devices have an N.O. output (1.0 at 30 VAC/VDC). The output on the CSDSC switch closes when the monitored current exceeds 70% full load amps and opens when the current falls below 60% full load amps, making the loss of load detection permissible without calibration. The output on the CSDECM switch closes when the monitored current exceeds the indicated minimum turn-on amps; it remains open when falling below the same threshold.
