I/O Wiring – Model 2400S PROFIBUS-DP and 
DeviceNet Transmitters
4.1
Overview
This chapter describes how to wire I/O for Model 2400S PROFIBUS-DP and DeviceNet transmitters.
Note: To wire I/O for Model 2400S Analog transmitters, see Chapter 3.
It is the user’s responsibility to verify that the specific installation meets the local and national safety 
requirements and electrical codes.
4.2
Moisture protection
When rotating or wiring the transmitter, guard against condensation or excessive moisture inside the 
transmitter housing. Be sure that the conduit openings are completely sealed after all installation and 
wiring procedures have been performed.
CAUTION
Condensation or excessive moisture entering the transmitter could damage 
the transmitter and result in measurement error or flowmeter failure.
To reduce the risk of measurement error or flowmeter failure:
Do not mount the sensor so that the conduit openings on the transmitter point 
upward.
Ensure the integrity of gaskets and O-rings.
Grease the O-rings every time the transmitter housing is opened and closed.
Install drip legs on conduit or cable.
Seal the conduit openings.
Fully tighten all covers.
