Why Choose the ABB CT-MXS.22S Multifunction Timer?
The ABB CT-MXS.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 5 selectable timing functions with two changeover relay outputs, making it suitable for applications requiring adjustable and repeatable time delays.
The CT-MXS.22S provides 2 x 10 selectable time ranges from 0.05 s to 300 h, allowing separate time settings to be configured for the relevant timing functions. It operates from a rated control supply of 24–48 V DC / 24–240 V AC and uses a voltage-related, non-floating control input for triggering the timing sequence.
The timer features 2 c/o (SPDT) relay contacts rated at 250 V / 4 A. Two remote potentiometers can be connected for fine adjustment of the time delays, while front-mounted controls provide precise local adjustment. The compact 22.5 mm wide housing uses screw connection technology with double-chamber cage terminals and is designed for DIN rail installation.

Flexible Timing for Industrial Automation
The ABB CT-MXS.22S provides five configurable timing functions within a single compact control device. Its asymmetrical ON- and OFF-delay, impulse, pulse generator and ON/OFF functions allow engineers to configure the timer for different machine sequencing and control requirements without changing the basic control hardware.
Two independent time ranges and two remote potentiometer connections provide additional flexibility where timing needs to be adjusted or controlled externally. The two changeover relay outputs allow the CT-MXS.22S to interface with contactors, control circuits, signalling equipment and other industrial automation components.
Typical Applications
- Industrial automation and control panels.
- Machine sequencing and timed control.
- Motor control applications.
- Conveyor and production machinery control.
- Timed switching and pulse generation.
- Flashing and signalling circuits.
- Process automation and equipment sequencing.
- Control systems requiring separate adjustable timing ranges.
- Applications requiring remote adjustment of time delays.
