zero voltage switching. Supply and output are galvanically isolated. On pulse - without control switch.
Versions available for DIN rail or 11-pole plug-in mounting. A jumper must be connected between 5 and 7 (B1 and B2).
When supply voltage is connected, the output is energized and the
timing period starts. The output is de-energized when the preset
time has elapsed.

When supply voltage is connected and the pause period has
elapsed, the output is energized. The output remains energized
