8 RELAY OUTPUT 8 PHOTO ISOLATOR INPUT BOARD

model : 8RELAY



The 8 channel relay output / isolator input board provides relay output function and isolator input function. The relay output part provides 8 Single Pole Double Throw (SPDT) relays to drive 8 digital output lines. Each relay channel can be used to control ON/OFF of external devices, to drive external high power relays, to activate alarms...etc. There are 8 LED indicators correspond to 8 relays, when relay is energized, the corresponding LED is light. The +12V power source is user selectable from internal PC bus or external power supplier.
 The isolator input part provides 8 Photo isolated Digital Input Channel, which allow the  input signals to be completely floated and prevent the ground loop. There are 8 LED indicators corresponds to 8 input channels, when the input channel is activated at high stat, the corresponding LED is light. The power source is user selectable from internal PC bus or external power supplier.
