Allen-Bradley 7209A1Q1X Photoelectric Relay 11 Pin

The ATC 7209A1Q1X Photoelectric Relay is an optically actuated relay housed in an 11-pin octal base, designed for industrial control where electrical isolation between the input signal and the switched load is essential. It delivers a 5 A load rating at 120 VAC and is specified for operation at 50/60 Hz, making it suitable for standard line-powered automation circuits. The unit combines a photoelectric input stage with a relay output, enabling reliable triggering from light or a photo sensor while switching a 120 VAC load; the 11-pin socket footprint supports straightforward replacement in compatible panels and sockets. This compact module is commonly used in automation systems for signaling, interlock functions, and simple load switching where optical isolation improves noise immunity and safety in control cabinets.
