Use AWG 26~16; The RED wire
indicates that it comes from
external current source
→
Connect to VIN1 or VIN2
Use AWG 26~16; The BLACK
wire indicates that it comes
from external GND
→
Connect to GND
Serial Resistor value depends
on current source
→
Connect in between
VIN1/VIN2 and GND
For example: Application
current source 4mA to 20mA,
recommend using 450ohm
resistor

Isolated Analog INPUT Setup
The 2CH isolated analog input supports external analog signals ranging from 0 to 10V. The two
options for connecting are as follows:
Analog Input with External Voltage Source
Analog Input with External Current Source
Use AWG 26~16; The RED
wire indicates that it comes
from external voltage source
→
Connect to VIN1 or VIN2
Use AWG 26~16; The BLACK
wire indicates that it comes
external GND
→
Connect to GND
