Allen-Bradley Safety Relay 700FSM4UU23

Product Description

This relay features 3 normally open (N.O.) and 1 normally closed (N.C.) contact configuration, ensuring reliable monitoring and control in safety applications. The 700FSM4UU23 operates on a 24V AC/DC control voltage and is rated for 6A at 240V AC, making it suitable for various industrial safety interlocks and emergency stop circuits. This safety relay is built with forcibly guided contacts, which means that the N.O. and N.C. contacts are mechanically linked, ensuring that they cannot be closed simultaneously. This feature is critical for safety circuits as it allows the safety control system to detect faults such as welded contacts. The relay is housed in a compact, DIN-rail mountable package, making it easy to integrate into existing control panels. The 700FSM4UU23 is also available with a manual or automatic reset function, depending on the specific model variant. With a mechanical life of 10 million operations and an electrical life of 100,000 operations, the 700FSM4UU23 is built for durability and long service life. It is designed to meet international safety standards, including EN 50205 and IEC 61810-3, ensuring compliance with global safety requirements. The relay is suitable for use in safety circuits up to PL e (ISO 13849-1) and SIL 3 (IEC 61508), making it a versatile choice for a wide range of industrial safety applications. The Allen-Bradley 700FSM4UU23 is a safety relay from the Bulletin 700FSM series, designed for use in safety circuits that require forced-guided contacts.

Technical Specifications

Version & Model Difference

The 700FSM series includes various models with different contact configurations and control voltages. The 700FSM4UU23 specifically has 3 N.O. + 1 N.C. contacts and operates on 24V AC/DC. Other models like 700FSM1UU23 have 2 N.O. + 1 N.C. contacts, while 700FSM4UU24 operates on 24V DC only. The 'U' in the model number indicates a universal (AC/DC) control voltage, while '23' denotes the specific contact arrangement and reset type. Always verify the exact model number for your application requirements.
