description

 The 8 channels relay output /photo isolator input board for pocket DIO provides relay output functions and photo isolator input functions. The relay output part provides 8 Single Pole Single Throw (SPST) 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.
