This section contains an illustration to assist you in wiring the following types of devices:
-
4-wire configuration
-
3-wire configuration
-
2-wire configuration
The diagram below shows an example of wiring for 2-wire devices:
The diagram below shows an example of wiring for 3- and 4-wire devices:
A 1-row busbar is used to provide PE for the 4-wire sensor. No busbar would be required if only 2- and/or 3-wire sensors were used.
The following diagram shows the field-side input circuitry.
