4-20 mA Output Connections
Connect the Ch. 1 and Ch. 2 4-20 mA current loop output to the J25 Phoenix connector terminals. Refer to
Similar to flow element connector TB1 the J25 connector is a detachable plug that plugs into the header socket on the board. The
connector plug accepts 28-16 AWG (
0.14 mm
2
- 1.5 mm
2
) wire (refer to
for wire size vs. length info).
Ch. 1 is dedicated to HART (see
above for connection details). Connect the instrument’s second 4-20 mA output (Ch.
2, J25-3) as required for your application. Use any RTN terminal (e.g., J25-4 through J25-6) for the 2
nd
channel current loop return.
The 3
rd
channel 4-20 mA current loop output is provided by connector J8 on the auxiliary board. This connector is also a detachable plug
that accepts 28-16 AWG (
0.14 mm
2
- 1.5 mm
2
) wire. Connect the 3
rd
analog output to the aux. board J8 as shown in
Figure 24 – Ch. 3 4-20 mA Output, J8 (Aux. Board)
