Notes:
Identify P/N 191914 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.
For 3-wire or 4-wire transmitters that require in
excess of 1.5w, use an external power supply. Or
install an auxiliary power board and connect
power wires to the Auxiliary VDC power terminal
block. For 3-wire transmitters, a jumper wire
between COM(-) on the input board terminal
block and PWR- on the Auxiliary Power terminal
block is required.
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 Transmitter
and select the type of transmitter from the list.
