The 16 Way Input Board (BRD25SIP) makes provision for 16 voltage free contacts to be terminated to
16 optically coupled inputs. Its application is primarily for the monitoring of controlled ancillary
equipment or to initiate an action / event due to a change of state from what is accepted as the norm.
