lectrical Characteristics
Power requirements
:
+3.3V~35VDC
Output signals
:
collector output of built-in pull-up resistor. Darlington drive, low level is
valid.
MAX voltage
:
supply voltage
Input signals
:
opto-isolator. low level is valid.
MAX current
:
50mA
Tip
:
To avoid the damage to interface, supply voltage can not exceed power requirement.
To avoid damage to interface, please connect cable after instrument is powered off.
Output signal can control signal and small pwer relay
(
instrument internal has integrated
reverse energy release diode
)
. Don
’
t use internal power source for large power relay.

In above figure
:
JP204 and JP205 is factory configuration 1-2 short circuit, trigger signal is
rising edge trigger.
If trigger signal is falling edge trigger, please short circuit 2-3 for JP204 and JP205, external
VCC floats.
