Type Terminal Name Description
Power
supply
+10 V-GND +10 V power supply
Provides +10 V power supply to an external unit. Max. output current:
10 mA.
Generally used to supply an external potentiometer of 1 to 5 kΩ
+24 V-COM +24 V power supply
Provide +24 V power supply to an external unit. Generally used for
power supply for DI/DO terminals and external sensors.
Max. output current: 200 mA

OP
Input terminal for
external power
supply
Connected to +24 V by default.
When DI1 to DI5 need to be driven by external signals, OP must
be disconnected from + 24 V and connected to an external power
supply.
Analog
inputs
AI1-GND Analog input 1
Voltage range of inputs: 0 to 10 VDC
Input impedance: 22 kΩ
AI2-GND Analog input 2
Either a voltage or a current input, determined by jumper J9
Input voltage range: 0 to 10 VDC
Input current range: 0 to 20 mA
Input impedance: 22 kΩ (voltage input), 500 Ω or 250 Ω (current
input) decided byJ10
