1 - One changeover output
2 - Two changeover outputs; B1/B2 selects sequential or simultaneous response

Output Contact Rating

10 - 10A contact version
16 - 16A contact version

Operating Voltage

Description

CDM6 electronic pulse relays change the output state in response to a control pulse at A1–S. Choose CDM6-11 for one changeover or CDM6-12 for two changeovers. The dual-output version offers separate output sequencing or simultaneous switching through the B1/B2 configuration.

Pulse response and dual-output operation

For CDM6-11, successive valid input pulses switch the output on and off. The minimum control pulse width is 25ms. For CDM6-12, leave B1/B2 open for the four-state sequence below, or bridge B1/B2 for the two outputs to switch together. The complete charts also show the illustrated response to a supply interruption.
