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.

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.

4.3 I/O wiring for Model 2400S PROFIBUS-DP transmitters

To connect the I/O wiring for a 2400S PROFIBUS-DP transmitter:

1. Remove the user interface cover and user interface module. See Section 2.4 for instructions.

2. Wire the transmitter to the PROFIBUS-DP segment according to the diagram in Figure 4-1.
Follow all local safety regulations.

3. Replace the user interface module and user interface cover.

Note: It is not necessary to open the power compartment to wire the outputs. Do not open the power
compartment unless you are also wiring the power supply.

Note: The PROFIBUS cable shield is required to be grounded at both ends. At the 2400S, ground the
cable shield in an appropriate cable gland. If an optional PROFIBUS-DP Eurofast M12 connector is
used, the cable shield is grounded via the threads of the connector.

WARNING

Hazardous voltage can cause severe injury or death.

To avoid the risk of hazardous voltage, shut off the power before wiring the
transmitter outputs.
