Internal power: 5V Max 1A.
Use internal power supply and connect to the following pins.
:
VCC
(
5V
)
:34 and 35 short circuit
Electrical parameters
Power requirements: +3.3V~24VDC
Output signal: collector output with built-in pull resistance. Optocoupler isolation. Low level
effective.
Maximum voltage: supply voltage.
Input signal: optocoupler isolation. Low level effective.
Maximum current: 50mA
Note: to avoid damaging the interface, the power supply voltage should not exceed the
power requirements.
To avoid damage to the interface, please connect after the instrument is closed.
If the output signal user is used to control the relay, the output terminal driven by
Darlington can drive the low-power relay and the signal relay.
Reverse diode has been integrated inside the instrument.

Figure: JP204 and JP205 factory configuration is 1-2 short. The trigger signal is triggered
by rising edge.
If the trigger signal is triggered by a falling edge, set both JP204 and JP205 to 2-3 short
connections, and the external VCC can float.
