    Abstract: Embodiments of this present disclosure include an input/output (IO) power supply module coupled to a load. The IO power supply module may include testing circuitry that couples to a voltage supply of the IO power supply module. The testing circuitry may perform an online load current test to verify performance of IO power supply module. To do so, the testing circuitry may include a current measurement circuit coupled to a switch. The current measurement circuit may receive a current via the switch while closed to determine whether the output current generated by the voltage supply is equal to a rated output current.

    Abstract: Safety and/or reliability may he improved in industrial control systems by optimally utilizing integrated circuit elements to reduce the amount of components required and to provide cross monitoring. In one aspect, circuitry that is part of an Integrated Circuit (IC) for controlling a first channel may also be used to monitor and provide safe operation for circuitry for controlling a second channel, and the circuitry for controlling the second channel may similarly be used to monitor and provide safe operation for the circuitry controlling the first channel. Circuitry may include a windowed watchdog circuit which may be used to monitor various events of the other circuitry, and safe operation may be provided by removing power from the other circuitry to provide a safe state.

    Abstract: A system includes a control device that coordinates within the system to control one or more operations of industrial automation equipment. The system also includes a terminal base that couples to the control device, wherein the terminal base includes a circuit. The system further includes a first input module and a second input module that couple to the terminal base. The first input module includes a first resistor and a first measuring device, and the second input module includes a second resistor and a second measuring device. The terminal base electrically couples the first resistor to the circuit and electrically isolates the second resistor from the circuit when the first input module and the second input module are coupled to the terminal block.
