Notes:
Identify P/N 191918 I/O Board and connect wires to the terminal blocks directly below the I/O slot that the board is in.
Use the wiring label located on the front panel that has a matching I/O part number.
Either channel can support any of the sensor types listed.
Each analog output is internally powered, 15 VDC, fully isolated.
To program the analog input, go to the Inputs menu, enter the menu for the I/O slot# and channel# (for example S21). Scroll to
