ABB 1SVR550127R4100 CT-ARE Time Relay

The ABB 1SVR550127R4100 is a CT-ARE electronic time relay designed for industrial automation and electrical control applications requiring accurate OFF-delay timing functions. As part of ABB’s CT-E timer relay family, this device provides reliable time control performance for industrial circuits, motor control systems and automation equipment.

Time relays are essential components in modern control systems because they allow electrical operations to be delayed according to specific timing requirements. They are commonly used for sequential control, motor management, machine automation and protection functions. The ABB CT-ARE provides a practical solution for applications where controlled switching after signal interruption is required.

The ABB 1SVR550127R4100 features a true OFF-delay function, meaning the relay output remains active after the control signal is removed and changes state only after the preset delay time has elapsed. This function is especially useful in applications where equipment needs to continue operating for a defined period after the main control signal disappears. :contentReference[oaicite:2]{index=2}

Product Overview

ABB 1SVR550127R4100 belongs to the ABB CT-E series electronic time relay product family. It is identified as the CT-ARE model and is designed as a single-function OFF-delay timer relay for industrial control applications.

The relay provides one changeover contact output configuration, allowing flexible connection to different control circuits. The output contact can be used for switching control signals, providing feedback functions or controlling external devices according to programmed timing requirements.

The ABB CT-ARE supports a wide control supply voltage range, including 24 V AC/DC and 220–240 V AC. This flexibility allows the same relay model to be integrated into different industrial electrical systems without requiring multiple versions for different supply conditions. :contentReference[oaicite:3]{index=3}
