CTF – Time relay with forcibly guided contacts

The CTF time relays are designed for safety-critical railway applications and provide reliable, hardware-based time control wherever PLC solutions are too complex and SIL relays are not required. They enable precise timing functions in control and signalling circuits and feature reliable contact technology with clear feedback on the switching status, supported by positively driven contacts for fault diagnosis. Thanks to their compact design, narrow mounting width and a wide time range from 40 ms to 80 h, they are also suitable for space-constrained applications.
