Relay board RB-4 has 4 SPDT type relays on it. For activating the relays 4 independent TTL level signals are used. Positive logic is used. Input signals are opto-isolated. Relay board RB-4 can be easily connected with all Audioms Automatika doo motion controllers.
For powering relay board RB-4, a 24VDC / 150mA voltage supply should be provided.
On the board, there are LED lights indicating whether there is power supply, as well as indicators of the states of relays.
Relay board RB-4 is fixated on a plastic base that is placed on the standard DIN rail.
