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.
UNPOWERED
4 WIRE
Use the wiring label located on the front
TRANSMITTER
panel that has a matching I/O part number.
Either channel can support any of the sensor
LITTLE DIPPER 2
types listed.
BRN
ORN
For 3-wire or 4-wire transmitters that require
RED
in excess of 1.5w, use an external power
BLK
supply. Or install an auxiliary power board
and connect power wires to the Auxiliary
PYXIS ST-500
VDC power terminal block. For 3-wire
transmitters, a jumper wire between COM(-)
GRN
on the input board terminal block and PWR-
WHT
on the Auxiliary Power terminal block is
RED
required.
BLK
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.
