2.7 Pulse Outputs
The terminal block provides two photocoupler outputs:
Screw clamp 1:
Emitter of photocoupler 1 (PP 1-)
Screw clamp 2:
Collector of photocoupler (PP 1+)
Screw clamp 3:
Emitter of photocoupler 2 (PP 2-)
Screw clamp 4:
Collector of photocoupler 2 (PP 2+)
Screw clamp 5:
ground earth
The DCF600HS generates a PPS (pulse per second, PP 1) and a PPM (pulse per minute, PP 2). This pulses
have a duration of 200 ms and are generated after the clock has synchronized first. The pulse output is elec-
trically insulated by a photocoupler.
In case of DCF77 reception failure the pulse generator is active even for the next 12 hours. After that pe-
riod the generator will be disabled.
