CTF Time relays

The CTF Time relays provide reliable, hardware-based timing control wherever PLC solutions are too complex and SIL relays are not required.

The CTF series relays are positively driven, multifunctional time-delay relays without a microprocessor. They were developed for safety-critical applications. Gold-plated contacts ensure reliable switching behavior at low and medium currents. The relays are available with two normally open contacts or one normally closed contact and one normally open contact, and with various timing functions, time intervals, and rated voltages. Custom configurations are available upon request.
