Abstract
An output termination board for a safety system is disclosed herein. The termination board provides simplified wiring between the output modules and the remote devices operated by the controller in the system. Redundant output signals are generated within each pair of output modules and combined such that one control signal is sent to each remote device. In addition, a program executing on the controller of the safety system performs a test to determine if each output module is operating normally. If the program detects a fault in either output module, the safety system may alternately shut down according to a fail-safe procedure or continue operating under a fault-tolerant mode of operation.
