Why Choose the ABB CT-MVS.22S Multifunction Timer?
The ABB CT-MVS.22S is a multifunction electronic time relay from the ABB CT-S timer range, designed to provide flexible timing and switching functions for industrial automation and control systems. It combines 10 selectable timing functions with two changeover relay outputs, providing a versatile solution for a wide range of timed control applications.
The CT-MVS.22S provides 10 time ranges from 0.05 s to 300 h and operates from a rated control supply of 24–48 V DC / 24–240 V AC. Its voltage-related, non-floating control input allows the selected timing function to be triggered as required by the control circuit.
The timer features 2 c/o (SPDT) relay contacts rated at 250 V / 4 A. Its compact 22.5 mm wide housing uses screw connection technology with double-chamber cage terminals and is suitable for DIN rail installation in industrial control panels.

Flexible Timing for Industrial Automation
The ABB CT-MVS.22S provides multiple timing functions within a single compact control device, allowing it to handle conventional ON-delay and OFF-delay operation alongside impulse, flasher, star-delta and pulse-generator timing functions. This flexibility makes it suitable for control systems where different timing sequences may be required.
Its wide AC/DC control supply range and voltage-related control input allow the CT-MVS.22S to integrate into a variety of industrial control circuits. The two changeover relay outputs provide additional switching flexibility for machinery, process equipment and automated control systems, while the second output can be configured for instantaneous operation where required.
Typical Applications
- Industrial automation and control panels.
- Machine sequencing and timed control.
- Motor control and star-delta starting sequences.
- Flashing and signalling circuits.
- Timed switching and pulse generation.
- Conveyor and production machinery control.
- Process automation and equipment sequencing.
- Industrial machinery control systems.
- Applications requiring multiple relay outputs and adjustable timing.
