ABB 1SVR630010R0200 Multifunction Time Relay CT-MFS.21

ABB CT-MFS.21 is a multifunction electronic time relay from the CT-S timer family with two changeover contacts (2 c/o) and a rated control supply of 24–240 V AC/DC. It provides ten timing functions across ten ranges from 0.05 s to 300 h, enabling everything from short delays to long sequencing in automation tasks. The device accepts volt-free control inputs (two inputs for start/pause timing) and supports remote adjustment via a potentiometer connected to Z1–Z2 (50 kΩ); the second contact can be configured as an instantaneous contact, and a sealable transparent cover is available as an accessory to prevent unauthorized changes. Supply is compatible with 24–240 V, and the AC frequency range is 47–63 Hz, while each output contact is rated for up to 250 V and 4 A. The official ABB order code is 1SVR 630 010 R0200. This makes CT-MFS.21 well suited for industrial control and timing applications that require flexible timing functions, reliable volt-free triggering, and simple delay/sequencing of auxiliary circuits.
