Eight LEDs each dedicated to the inputs and outputs signalize if a channel is high or low.
The OR8 is powered with 9-40V but can also be configured to 5V supply. The supply voltage is also connected via screw-clamp terminals.
DIN Rail Mounting.
The optocoupler and relay board is suitable for DIN rail mounting. A DIN rail carrier with bracket is already included with the delivery of the OR8.
Particularly simple is the connection to the digital I/O interface USB-PIO as only a 25-pin D-Sub extension cable is needed for connecting.
