The new CTF series, a range of 2-pole time relays with forcibly guided contacts for safety-critical control and signalling circuits in railway and industrial applications. The new CTF series has been developed for applications where a reliable timing function with unambiguous switching states is required. As a hardware-based alternative to PLC timing functions and SIL relays, it enables a cost-effective and straightforward system design. © ComatReleco AGHardware-Based Timing Function With Clear Switching StatesThe CTF series supports timing functions in safety-critical control and signalling circuits in the railway and industrial sectors.
