Using the 1U Termination panel for 32 optically isolated inputs
Connection
Connect the termination panel with the SCSI cable included in the package.
Each panel provides eight 5-position terminal blocks (4 inputs + 1 common).
An 8-position dipswitch allows to selectively group commons together for ease of wiring.
Schematic diagram
The input is OFF by default.
It switches ON if an external power supply between +5 and +25VDC (either polarity) is applied between the
common and the digital inputs.
