Output Wiring – Model 1700/2700 Intrinsically Safe Transmitters

5.3Safe area output wiring

The following notes and diagrams are designed to be used as a guide for wiring the Model 1700 or Model 2700 outputs for safe area applications.

5.3.1Safe area mA output wiring

The following 4–20 mA wiring diagrams are examples of proper basic wiring for the Model 1700 mA output or Model 2700 primary and secondary mA outputs.

Note: This diagram shows the Model 2700, which has a secondary mA output. If you are using the Model 1700, the secondary mA output does not exist.
