External Relay Board R8 Expands Digital-I/O Channels
The relay boards R8 are ideal to monitor and control digital states. The digital inputs and outputs can be connected directly via a screw-clamp connection. Via relays, the R8 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).
- Power supply: 5 V.
- Status indication via LEDs.
- Screw terminals.
- DIN rail carrier with bracket optional for the R8 (accessory ZU-EW).
