3RP2527 time relay - two-wire time relay
The two-wire time relay is connected in series with the load. Timing begins after application
of the control supply voltage. The semiconductor output then becomes conducting, and the
load is under power.
4 time ranges can be set with the time range selector switch:
● 0.05 s - 1 s
● 0.2 s - 4 s
● 1.5 s - 30 s
● 12 s - 240 s
Note
The desired operating time is set precisely with the operating time adjustment switch.
Note
Rated operational current, residual current in the case of a non-switched output, and voltage
drop in the case of a switched output must be taken into account. You can find the values in
the technical specifications (Page 83).
