Allen-Bradley 193-EIO-43-120 E300 Control Module

Allen-Bradley 193-EIO-43-120 E300 Control Module is the 4-input, 3-output I/O module that sits in Rockwell Automation’s E300 electronic overload relay family. This 120 V AC variant provides four inputs and three outputs to support the control and signaling needs of the E300 protection circuit, and is specifically identified by the 193-EIO-43-120 model number for 120 VAC operation. In the E300 architecture, this control module works alongside a sensing module and a communications module to form a complete motor protection solution, enabling sensing, logic, and inter‑module communication within industrial panels. The 193-EIO-43-120 is designed for E300 Overloads within the 193/592 IEC/NEMA family, allowing integration with motor starters and protection relays to deliver fast, reliable protection against overload conditions and faults. Typical use cases include safeguarding industrial motors in machinery and production lines, where precise protective signaling to control hardware helps minimize equipment damage and downtime.
