Allen-Bradley 700-C110A1 Programmable Logic Controller Module

Allen-Bradley 700-C110A1 is a compact electromagnetic control relay designed for industrial control panels and legacy automation setups. It provides a single normally open (NO) and a single normally closed (NC) contact, enabling basic on/off logic with a single coil. The coil accepts AC operation with voltage options of 120 VAC at 60 Hz or 110 VAC at 50 Hz, allowing compatibility with common North American and international control circuits without a dedicated DC supply. The part is cross-referenced as 700C110A1 and is associated with 5945-00-237-2575 in supplier listings, reflecting its role as a standard Allen-Bradley relay in older controllers and PLC-related installations. This relay functions as a simple signal and interlock device within industrial equipment, suitable for switching auxiliary circuits, timer circuits, or safety interlocks where discrete relay logic is required rather than a solid-state device. With its straightforward contact configuration and AC coil design, it remains compatible with equipment designed for legacy AB relays and is commonly found in automation, machine tools, and process-control applications that rely on discrete relay logic.
