24 +24V
Internal 24V+ of the controller (do not connect any circuit)
25 GND 0V
Wiring mode of output signal:
The output is collector open circuit. If the external load is inductance load, e.g. relay, a freewheeling diode should
be connected, as shown below:
EXTCOM or DOUTnGND
EXTCOM terminal is connected to negative end of internal power supply, and output signal is connected to
respective terminal.
The power voltage should be lower than 24V and shouldn’t exceed 30V. Do not connect the anode and
cathode reversely or short circuit the load, or else the module will be damaged.
