NOTE: Never connect the loop wiring to the test terminals.

ANALOG MODE

In the analog mode of operation, the electrical connections are
made in the typical two-wire, four to 20-milliampere configura-
tion as shown in Figure 2-4. Both a + (positive) and -
(negative)
the signal leads.
NOTE: Insure that the temperature rating of the wire is suitable for
the environment.
The signal terminals located in the electronics housing accept
wire sizes up to 14 AWG. The signal wiring supplies all power
to the transmitter. The power supply limits are 12 to 53 VDC
(12 to 42 VDC for certified application) across the transmitter
inputs. Refer to Figure
