ABB 1SVR730020R0200

The CT-MVS.21S is an advanced electronic time relay designed for diverse applications within the CT-S timer range. It supports a variety of timing functions including Impulse OFF, Impulse ON, OFF-Delay, ON-Delay, and Star-Delta. With a time range spanning from 0.05 seconds to 300 hours, this relay is adaptable to numerous timing requirements.

Operating at a rated control supply voltage of 24 to 240 V AC/DC, the device features a dual changeover (2 c/o) output capable of handling a rated operational voltage of 250 V and current ratings up to 4 A in AC-12 conditions. The control input allows for voltage-related triggering, enhancing its functionality.

The CT-MVS.21S also includes a provision for connecting a remote potentiometer, facilitating precise adjustments of the time delay. A noteworthy feature is the option to configure one of the c/o contacts as an instantaneous contact. Additionally, a transparent cover can be securely sealed to prevent unauthorized modifications.

Designed with screw connection technology, it employs double-chamber cage connection terminals for enhanced reliability. The relay has a compact profile with dimensions of 22.5 mm width, 85.6 mm height, and 103.7 mm depth, making it suitable for DIN rail mounting.

This relay meets various standards including IEC/EN 61812-1 and UL 508, ensuring compliance with industry requirements. The device operates effectively in ambient temperatures ranging from -40 to +60 °C and can function at altitudes up to 2000 m withou...
