ABB 1SVR550120R1100 Safety Relay Module 24V DC

ABB CT-ARE 1SVR550120R1100 is a true OFF-delay time relay with a single changeover (SPDT) contact, part of ABB’s CT-ARE timer family. It operates from a 110–130 V AC control supply and delivers a 0.1–10 s timing window, enabling a defined delay after input de-energization for simple safety-sequence tasks. The output is rated up to 250 V at 4 A, allowing direct switching of contactors or other control loads in standard industrial circuits. Weighing about 0.08 kg per piece, this compact module is designed for DIN-rail or cabinet mounting and is commonly used for start/stop interlocks, post-start delays, or reset-time logic within machine safety or automation circuits. Note that this variant uses 110–130 V AC rather than 24 V DC, so system voltage should be verified when selecting the part. The catalog number 1SVR550120R1100 denotes a 0.1–10 s CT-ARE timer with one SPDT output, aligning with ABB Jokab Safety and broader ABB safety-relay configurations in typical PLC-driven control schemes.
