CT-MXS.22S 1SVR730030R3300

The CT‑MXS.22S is a multifunction electronic time relay in ABB's CT‑S timer series. It combines multiple timing functions in a compact unit for industrial applications. It supports five different timing functions and offers adjustable time ranges from 0.05 seconds up to 300 hours. The relay can be triggered via a voltage-related control input and allows connection of two remote potentiometers for precise time adjustments.
