Clock generator from the SB-Line series. The function and time range selection is set on the front using rotary switches. The displays for the time elapsed, switching status and operating voltage enable constant monitoring of the functional status. Function description: after the operating voltage is applied, the output relay is activated for the set time - on - and remains in the idle state for the set time - off. The output relay clocks with this pulse-pause ratio until the operating voltage is switched off. Separately adjustable pulse and pause times, optionally pulse or pause start. Approvals: UL and CSA
