Connect Digital Signals. Quite Simple.

The optocoupler and relay board OR8 is ideal to monitor and control digital states. The digital inputs and outputs can be connected directly via a screw-clamp connection.

8 Optocoupler Inputs. 8 Relay Outputs.

The eight optocouplers on the OR8 convert digital inputs in the voltage range of 5..30V into TTL signals. Via relays, the OR8 switches eight control lines (TTL) with up to 6A.

Clearly Safe.

Due to the galvanic isolation of the channels from each other and from the data acquisition and control system, the whole system is perfectly protected.
