Signal Connections
The J7 and J8 terminal blocks are provided for signal connections. These terminal blocks have 3.5 mm pitch spacing and accept 28 AWG
(min.) to 14 AWG (max.) wires. Observe signal wire routing as described in
4-20 mA Analog Outputs
The instrument is provided with a 4-20 mA current loop as an integral part of the HART signal output and a second 4-20 mA current loop
for general purpose use. Refer to
for the HART loop and general purpose 4-20 mA loop
connector pin assignments. By default Channel 1 (HART) is assigned flow and Channel 2 (general purpose) is assigned temperature. See
also
V Menu: Configure Outputs (4-20 mA and Source/Sink Outputs)
for details on setting up the analog outputs.
