T3
Test time
Relate to Setup
Test time = Charge time + Test Time
+ Discharge Time
T4
Delay output of sorting results
1ms
T5
Wait time after triggered
0s
Period Comparison Mode
After a complete period test Charge --> Test --> Discharge --> Stop is finished, then compare the
measured results with the preset limit reference.
This mode is safer because there is no voltage output at the test end after testing.
12.4 Wiring Method
Power Supply
Built-in isloation power supply, external power is no need, but common ground ISO-COM is
a must.
ISO-COM: P19~P21
Output Signal
Optoelectronic isolation with drive core, leakage open circuit output
The maximum of load voltage is 30V, it is commended to use 24V.
The maximum of output current: 50 mA
Note: When using the osiclloscope or multimeter to confirm the ouput level, the output signal
should pull up to power (count KΩ) and then to start measurement.
Input Signal
Optoelectronic isolation, low level valid.
The maximum of current: 50 mA
