External Optocoupler and Relay Board OR8 Expands Digital-I/O Channels
The optocoupler and relay boards OR8 are ideal to monitor and control digital states. The digital inputs and outputs can be connected directly via a screw-clamp connection. The eight optocouplers on the OR8 convert digital inputs in the voltage range of 5...30 V into TTL signals. Via relays, the OR8 switch with up to 6 A. Eight LEDs each dedicated to the inputs and outputs signalize if a channel is high or low.
- 8 relay outputs (max. 60 V/6 A).
- 8 optocoupler inputs (5..30 V, max. 17 mA).
- Power supply: 5 V, 9...40 V.
- Status indication via LEDs.
- Screw terminals.
- Incl. DIN rail carrier with bracket.
