Communication
terminal
A: 485+; B: 485-
+10V, GND
Analogue power
supply
Analogue input use +10V power supply, max. output current is 100mA
•
Change to +5V by setting jumper on CN15
GND is isolated to COM
AI1, AI2
Anglogue input
AI1, AI2 input voltage: 0 - 10V (input impedance: 22kΩ)
AI2 input current: 0 - 20mA (input impedance: 500Ω)
•
AI2 can select voltage/current; AI2 = current: input impedance is selectable;
AO1, AO2
Anglogue output
Output voltage/current signal: 0 - 10V/0 - 20mA
Programmable output
GND
Anglogue ground
DI1 - DI6
Digital input
Programmable bipolar optional input signal, compatible with DC/AC input
signal.
Input voltage: 15VDC - 56VDC, compatible with 24VDC/36VDC/48VDC
