1SVR730010R3200 ABB CT-MBS.22S Multifunction Timer 2C/O

Why Choose the ABB CT-MBS.22S Multifunction Timer?

The ABB CT-MBS.22S is a versatile multifunction electronic time relay from the ABB CT-S timer range, designed to provide flexible timing and switching functions for industrial control and automation systems. It combines ten selectable timing functions with two changeover relay outputs, allowing a single compact device to handle a wide variety of control requirements.

The CT-MBS.22S provides 10 time ranges from 0.05 s to 300 h and operates from a rated control supply of 24–48 V DC or 24–240 V AC. A volt-free control input can be used to initiate timing, while a remote potentiometer can be connected for fine adjustment of the selected time delay.

The timer features 2 c/o (SPDT) relay contacts rated at 250 V / 4 A, with the second changeover contact selectable as an instantaneous contact. Its 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-MBS.22S provides a broad selection of timing functions within a single control device, allowing one timer to handle applications ranging from conventional ON-delay and OFF-delay operation through to impulse, flasher, pulse-forming and star-delta timing sequences. This flexibility can simplify control panel design where different timing requirements need to be accommodated.

Its AC/DC control supply compatibility, volt-free control input and two changeover relay outputs make the CT-MBS.22S suitable for integrating timing functions into industrial automation equipment. The optional remote potentiometer provides additional flexibility where timing needs to be adjusted away from the timer itself.

Typical Applications

• Industrial automation and control panels.
• Machine sequencing and timed control.
• Motor control and star-delta starting sequences.
• Flashing and signalling applications.
• Timed switching and pulse generation.
• Conveyor and production machinery control.
• Process automation and equipment sequencing.
• Applications requiring adjustable ON/OFF timing.
