Channel 1
I/O Board Part Number
Notes:
Identify P/N 191913 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.
