 5 Terminal assignment 2-wire, 4-20 mA HART, 4...20mA
A Without integrated overvoltage protection
B With integrated overvoltage protection
1 Connection current output 2
2 Connection current output 1
3 Supply voltage for current output 1 (e.g. RN221N); Observe terminal voltage
4 Cable screen; observe cable specification
5 HART communication resistor (≥250 Ω): Observe maximum load
6 Connection for Commubox FXA195 or FieldXpert SFX350/SFX370 (via VIATOR Bluetooth modem)
7 Analog display device ; observe maximum load
8 Analog display device ; observe maximum load
9 Supply voltage for current output 2 (e.g. RN221N); Obeserve terminal voltage
10 Overvoltage protection module
11 Current output 2: Terminals 3 and 4
12 Terminal for the potential equalization line
13 Cable entry for current output 1
14 Cable entry for current output 2
This version is also suited for single-channel operation. In this case, current output 1 (terminals
1 and 2) must be used.
