Why Choose the ABB CT-VWC.12 Time Relay?
The ABB CT-VWC.12 is a compact and reliable electronic impulse-ON time relay designed for precise timing and sequencing in industrial control and automation systems. As part of the established ABB CT-C timer relay range, it provides a defined output pulse when the control signal is applied, making it suitable for machinery, control panels and electrical automation applications.
This single-function timer relay provides seven selectable time ranges from 0.05 s to 100 h, allowing the required impulse duration to be configured for a wide range of control applications. Its compact design, front-mounted adjustment controls and clear operating characteristics simplify installation, commissioning and operation.
With a rated control supply voltage of 24–48 V DC or 24–240 V AC and one changeover relay output, the CT-VWC.12 provides flexible switching capability for industrial control circuits. Its compact 17.5 mm wide housing is well suited to installations where control panel space is limited.
