AB 2711-M3A18L1 Central control module

Product Description

Allen-Bradley input modules are electronic devices that interface with a programmable logic controller (PLC) or other automation devices. They receive signals from various sensors, switches, and other field devices, converting them into a digital format that can be understood by the PLC. These modules play a crucial role in gathering data from the physical world and providing it to the control system.
