PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-SIM is a dedicated simulator module engineered for the PLC-5 system architecture. It installs directly into any Bulletin 1771 universal I/O chassis. The module occupies a single chassis slot during testing or maintenance operations. It provides manual hardware simulation for field devices and system troubleshooting. Internal backplane power consumption is rated at 0.2 amperes.
The 1771-SIM integrates eight toggle switches that simulate discrete open and close contact inputs. It also features eight status indicators that display discrete output states. Technicians use this unit to verify program logic without connecting physical field sensors. The assembly pairs with a standard 1771-WN wiring arm inside the chassis. It weighs approximately 1.69 lbs (0.77 kg) in total.
