Terminal Description
+10, GND +10V power supply
Analogue input use +10V power supply, max. output current is 100mA
GND is isolated to COM
AI1, AI2 Anglogue input
AI1 input voltage: 0 - 10V (input impedance: 34kΩ)
AI2 input voltage: -10V - 10V (input impedance: 34kΩ)
AI2 input current: 0 - 20mA (input impedance: 500Ω)
• AI2, AI3 can select voltage/current
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
Input voltage: 0 - 30VDC
DI1 - DI5 input impedance: 4.7kW, DI6 input impedance: 1.6kΩ
• DI6 can be selectable for high-frequency input, max-frequency
50kHz
P24, COM Digital power supply
Digital input use +24V as supply, max. output current is 200mA
COM is isolated to CME
SEL
Digital input common
terminal
SEL and P24 are connected by default (factory setting)
• Disconnect SEL and P24 when use external power to drive DI
DO1, CME Digital output
Programmable optocoupler isolation
• DO1, DO2 open collector output, output voltage: 0 - 30VDC, max.
output current 50mA
• DO2 can be selectable for high-frequency output, max-frequency
50kHz
CME is isolated to COM, shortly connected to COM by default
• Disconnect CME and COM when they are isolating output
DO2, COM Digital output
