Electrical connectionsTable 11-1:
Type Description
Input/output connections Three pairs of wiring terminals for transmitter outputs. Screw
connectors accept one or two solid conductors, 14 to 12 AWG
(2.5 to 4.0 mm
2
); or one or two stranded conductors, 22 to
14 AWG (0.34 to 2.5 mm
2
).
Power connections One pair of wiring terminals accepts AC or DC power.
One internal ground lug for power-supply ground wiring.
Screw connectors accept one or two solid conductors, 14 to
12 AWG (2.5 to 4.0 mm
2
); or one or two stranded conductors, 22
to 14 AWG (0.34 to 2.5 mm
2
).
Digital communications main-
tenance connections
Two clips for temporary connection to the service port.
Core processor connection The transmitter has two pairs of terminals for the 4-wire connec-
tion to the sensor-mounted core processor:
• One pair is used for the RS-485 connection to the core pro-
cessor
• One pair is used to supply power to the core processor
Plug terminals accept solid or stranded conductors, 24 to
12 AWG (0.40 to 3.5 mm
2
).
