An industrial process field device includes an active component, a switch, a switch monitor, and a controller. The active component may be a sensor configured to sense a process parameter, or a control device configured to control a process of the industrial process. The switch is electrically coupled to first and second terminals and is configured to electrically connect the first and second terminals when in a closed state, and electrically disconnect the first and second terminals when in an open state. The switch monitor is configured to detect a current state of the switch corresponding to the closed or open state, and generate a state output indicating the current state. The controller is configured to set the switch in the open or closed state, and generate a notification based on the state output that indicates at least one of the current state of the switch and a condition of the switch.

An output module includes multiple outputs, each output having switches, wherein the switches are configured such that a load is connectable between the switches, and a calibration unit configured to disconnect the load from the switches for a calibration period, monitor a behavior of the load while disconnected, and store samples of the behavior of the load. Further aspects of the present disclosure relate to a control system and a method for testing an output module connected to a complex load.
