Abstract:
1. An input termination device for use in a safety system, the safety system having at least one industrial controller, a first input module, a second input module, and an output module, the input termination device comprising: a circuit board; a switch arranged on the circuit board to selectively supply a DC voltage to the circuit board according to a signal from the output module; a field supply connector mounted on the circuit board having at least one terminal connected to the switch and configured to supply the DC voltage to at least one remote device; a field return connector mounted on the circuit board having at least one terminal configured to accept a DC voltage input signal from the remote device; a first input module connector mounted on the circuit board configured to transmit each of the signals from the field return connector to the first input module; and a second input module connector mounted on the circuit board configured to transmit each of the signals from the field return connector to the second input module.
