minimum of 250 ohms resistance in the loop.

To connect external power to the 4–20 mA loop, connect -DC to Terminal 1 and +DC to
Terminal 2.

NOTE

To connect any of the other output options (pulse output and/or digital input/output), consult
the comprehensive product manual.

Transmitter to Sensor Wiring

A single dedicated conduit run for the coil drive and electrode cables is needed between a
sensor and a remote transmitter. Bundled cables in a single conduit are likely to create
interference and noise problems in your system. Use one set of cables per conduit run.
