JFET output (D1 – D4):
Connector pin D is internally connected via the drain-source
path of a JFET (self-conducting type) to the negative potential
of output 1. V
voltage level (V
JFET should not exceed 2.5 mA. The JFET is protected by a
0.5 W Zener diode of 8.2 V against external overvoltages.
NPN output (D5 – D8):
Connector pin D is internally connected via the collector-
emitter path of a NPN transistor to the negative potential of
output 1. V

Threshold tolerances and hysteresis:
If V
and rectifier is measured. Consequently, this voltage differs
from the voltage at the connector pins by the voltage drop V
across input filter and rectifier. The threshold level of the D1
and D8 options is adjusted in the factory at nominal output
