is active with both methods.
The voltage of the "No" contact is maximized at 15 V by a Zener-diode. Make sure that the voltage
caused by the resistance of the circuit breaker and the injected current from the TRIP+ module
does not reach 10 V. In case of PSTP+ modules, this voltage is 8 V (PSTP+/4201) and 13 V
(PSTP+/2101).
Our TRIP+ modules are made to switch DC circuits.
Using reversed polarity or AC voltage can
cause the damage of the internal circuits.
2.1.1 3-wire TRIP+ wiring methods
Figure 2-1 3-wire TRIP+ wiring
It is possible to use parallel connected TRIP+ modules. In this case the negative contacts must
be common.
