Time relays

The RXKL 1 relay is a universal timer that provides on-delay or pulse timing functions. The same timer is suitable for operation on all common DC battery voltages in the 24 - 250 V range as well as AC voltages 24 - 240 V 50 to 60 Hz, which makes it easy to specify and use also as a universal spare part for existing applications.

The timer is used in relay applications where reliability demands are high as well as where very high setting accuracy is needed.

The timer is suitable for most power system protection, logic and signalling functions as well as for high demanding and short time precision applications, e.g. breaker failure relaying and where two change-over contacts are needed. The wide setting-range permits RXKL 1 to be used as a replacement for many other types of timers. The wiring-configuration is pin-compatible with earlier types, e.g. RXKN 1, RXKB 1 and RXKE 1. The relay can also replace the RXKP 2 AC timer in function except the instantaneous start-indication contact.

• Continuous, one-shot or flashing function
• Timing range 20 ms - 99 hours
• Operation for AC 24 - 240 V and DC 24 - 250 V with the same relay
• High accuracy using microprocessor technology and digital setting

RXKM 2H is used where high operating requirements are necessary, such as in protection systems, automation control equipment, industrial processes, and control and signal systems. With the wide time setting ranges together with large operative ranges for DC as well as AC supply voltages, RXKM 2H can replace most other types of time relays.

RXKM 2H is a DC or AC voltage operated, high-precision, digital on-delay and off-delay time relay utilising a microprocessor for the time functions. The relay has built-in electromechanical output relays providing one instantaneous and two delayed medium-duty change-over contacts.
