The RXKA 1 relay is a universal low cost programmable timer that provides pick-up, drop-out or pulse timing functions.
The timer is used in relay applications where reliability demands are high but setting accuracy down to the millisecond is not of the issue. The timing repeatability is good and is suitable for most power system protection, logic and signalling functions, where only one change-over contact may be required.
For high demanding and short time precision applications e.g. breaker failure relaying and where two change-over contacts are needed we recommend the RXKL 1 timer. The wide range of settings permits RXKA 1 to be used as a replacement for many other types of timers.
