Why Choose the ABB CT-MFS.21P Multifunction Timer Relay?
The ABB CT-MFS.21P is a compact and versatile multifunction electronic timer relay designed for precise timing and switching control in industrial automation, electrical control and machine systems. As part of the ABB CT-S timer relay range, it provides 10 selectable timing functions, 10 time ranges and two changeover outputs for flexible control applications.
The CT-MFS.21P provides 10 timing functions with selectable ranges from 0.05 s to 300 h. Two control inputs support volt-free triggering, while the second changeover contact can be selected as an instantaneous contact. A remote potentiometer can also be connected for fine adjustment of the time delay.
With a rated control supply voltage of 24–240 V AC/DC and 2 C/O (SPDT) output contacts rated at 250 V / 4 A, the CT-MFS.21P provides flexible timing and switching control in industrial automation and control panels. Its compact 22.5 mm housing with maintenance-free push-in terminals is designed for straightforward DIN-rail installation.
