The 8 channels relay output / photo isolator input adapter provides relay output functions. The relay output part provides 8 relays to drive 8 different output channels. Each relay channel can be used to control ON/ OFF of external devices, to drive external high power relays, to activate alarms¡K etc.

The photo isolator input part provides 8 photo couple digital input channels, which allow the input signals to be completely floated and prevent the ground loop.
