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