CCM 1010

8-channel Contact Closure Module (EoL)

The CCM 1010 series transports eight contact closure signals unidirectional over one multimode optical fiber. These modules are monitored by status LEDs indicating the link condition and its internal synchronisation. The contact closures are designed to be fail-safe. They fall back to ‘open' in case of data failure, connection loss or power loss.

The CCM 1010 /RS-232 contact closure multiplexer system can transmit eight independent contact closure signals unidirectional over one RS-232 data link.
