MKS AIO Module Pin-outs

Picture

I/O Connector (Pinout signal mapping)
Analog inputs are represented by AI1_P, AI1_N, AI2_P… and Analog outputs are represented by AO1_P, AO1_N, AO2_P…

Voltage Pinout
Pin A1 starts on the top left of the connector shown in the picture, B1 starts at top right.

Current pinout
Same pinout as above except for AO1_N, AO2_N, AO3_N and AO4_N connects to AGround

±15V input connector

The -15V from the 3 pin connector gets routed to pins A17 and B17. The +15V from the 3 pin connector gets routed to pins A15 and B15.
The AGround from the 3 pin connector gets routed to A14, B14, A16 and B16.
This input is optional in case the user needs to power upto 2 devices that need ±15V.

Note- One ±15V power supply can power upto 2 devices that need this voltage, as long as the 2 devices pull less than 1.1A overall. Any devices or devices that pull more than 1.1A overall cannot be powered using the 3 pin connector and will require it's own dedicated power supply.
