5.4. Connecting to passive current transmitter

The DT4220 E is a modern type of process indicator family. The
old type (DT4220) and this new type have same functions and
same options but the input signal connecting are not compatible.

The following figure shows the wiring plan:
The instrument is connected to passive current transmitter via TS
(transmitter supply) option.

Wiring plan

1. Pull out the terminal so you can make connection easier.
2. Loosen terminal screws.
3. Insert the wire ends into the open terminals according to the wiring
plan.
4. Screw the terminal in.
5. Check the hold of the wires in terminals by pulling on
them firmly.
6. Push in the terminal.

Remark

If the instrument does not have the TS option, you need to use an
external power supply for passive transmitter.
