Mac 225B-117AA Industrial Relay Module is a relay-based control device used in industrial automation to switch electrical circuits. The model 225B-117AA is manufactured by Mac. This module provides a straightforward interface between control logic and loads, allowing a low-power control signal to energize or de-energize external devices such as indicators, actuators, or other relays. In automation systems, relay modules like this simplify wiring and support reliable switching of loads within control cabinets or panels, serving as a modular building block in broader control architectures.
