The Allen-Bradley 1760-SIM is an input and output simulator module from the Rockwell Automation 1760 Pico Controllers series, designed for testing and troubleshooting programs on compatible 1760 series Pico controllers. It includes an input simulator board, an output simulator board, and a wall-mounted power supply. The 1760-SIM module features eight pushbuttons that correspond to the eight inputs of compatible controllers, allowing users to simulate photoswitches, limit switches, and proximity sensors for accurate and efficient program validation in industrial automation systems.
