Mono-function, plug-in, delay on release, miniature time relays 60 s covering 2 individual time ranges. These economical timers are often used to switch on an exhaust fan and keep it running for a certain period of time after disconnection of power supply.

The relay operates immediately after power supply is applied. When power supply is interrupted, the time period starts and at the end of the set time the relay releases. If power supply is reapplied before the relay releases, the time is reset and the relay remains on. 121/B 128 monitor that power supply is applied. If power supply is interrupted, the relay starts e.g. an alarm (battery driven) after the time period has expired. Please note B 128 and B 121 should not be operated by pulses shorter than 500 ms.
