1SVR730021R2300 ABB CT-MVS.23S Multifunction Timer 2C/O

Why Choose the ABB CT-MVS.23S Multifunction Timer?

The ABB CT-MVS.23S 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.23S provides 10 time ranges from 0.05 s to 300 h and operates from a rated control supply of 380–440 V AC. Its voltage-related, non-floating control input can be used to start, stop or pause timing, or to select the required timing function depending on the application.

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 designed for DIN rail installation in industrial control panels.

Flexible Timing for Industrial Automation

The ABB CT-MVS.23S 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, pulse-forming, accumulative and ON/OFF timing functions. This flexibility makes it suitable for control systems where different timing sequences may be required.

Its 380–440 V AC control supply and voltage-related control input allow the CT-MVS.23S to integrate into suitable industrial control circuits. The two changeover relay outputs provide flexible switching for machinery, process equipment and automated control systems.

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 adjustable timing with a 380–440 V AC control supply.
