The CM444 relay modules provide an easy way to interface Bosch readers lock outputs to standard door locks. Because of small physical size, it can easily be located in the wall cavity if required.
The power side of the CM444 connects to the LAN+ and the lock output of Bosch prox/smartcard readers/keypads with a lock output.
The CM444 then provides changeover relay contacts to drive any lock (via a separate power supply) so that power for the lock is not being taken from the LAN.
