Product Overview

The Emerson SE4022 is a DeltaV™ S-Series Profibus DP Interface Card. This card integrates Profibus DP device signals directly into control logic. It reduces wiring costs by using a native bus interface. The design eliminates data mapping for simpler integration. You can mix bus technologies to meet your application requirements.

Technical Specifications

The Emerson SE4022 has one physical port. It supports up to 64 Profibus DP devices per card. The card includes a switchable termination resistor for network configuration.

Key technical parameters include:

• Number of Ports: 1

• Number of Devices: 64

• Storage Temperature: -40°C to 85°C

• Operating Temperature: -40°C to 70°C

• Relative Humidity: 5% to 95% (non-condensing)

• Protection Rating: IP 20

• Conformal Coating: Yes (Class G3 compliant)

The card withstands 10 g shock for 11 ms (½-sine wave). Vibration tolerance is 1 mm peak-to-peak from 5 to 13.2 Hz. From 13.2 to 150 Hz, it handles 0.7 g.

Redundant Master Operation

The SE4022 supports redundant Profibus DP master configurations. Redundancy ensures continuous communication if one master fails. The system automatically switches to the backup master without process interruption.

Redundant mode baud rate and distance specifications:

• 19.2 Kbit/sec: 1200m per segment

• 93.75 Kbit/sec: 1200m per segment

• 187.5 Kbit/sec: 1000m per segment

• 500 Kbit/sec: 400m per segment

• 1500 Kbit/sec: 200m per segment

Note that 9.6 Kbit/sec distance is not applicable for redundant mode.

Simplex Master Operation

The SE4022 also works as a simplex (non-redundant) master. This mode offers the same baud rate options with different distance limits.

Simplex mode baud rate and distance specifications:

• 9.6 Kbit/sec: 1200m per segment

• 19.2 Kbit/sec: 1200m per segment

• 93.75 Kbit/sec: 1200m per segment

• 187.5 Kbit/sec: 1000m per segment

• 500 Kbit/sec: 400m per segment

• 1500 Kbit/sec: 200m per segment

Choose simplex mode for lower cost applications without redundancy requirements.

Certifications and Hazardous Area Approvals

The Emerson SE4022 holds multiple international certifications. It meets CE and EMC standards per EN 61326-1. FM and CSA approvals cover North American installations.

Hazardous area certifications include:

• FM (USA): Class I, Division 2, Groups A, B, C, D, T4

• cFM (Canada): Class I, Division 2, Groups A, B, C, D, T4

• ATEX: II 3G Ex ec IIC T4 Gc

• IEC-Ex: II 3G Ex ec IIC T4 Gc

Marine certifications include ABS and DNV (IACS E10). The card has a G3 conformal coating for harsh environments.

Installation Guidelines

Follow these steps for proper installation:

1. Mount the SE4022 in a DeltaV S-Series I/O carrier.

2. Set the switchable termination based on your network position.

3. Connect the Profibus DP cable to the single port.

4. For redundant mode, install two SE4022 cards in parallel.

5. Configure baud rate based on your cable length (see tables).

6. Assign up to 64 devices per card in your DeltaV logic.

Do not exceed the maximum segment lengths for your chosen baud rate. Use certified Profibus DP cables for reliable communication. Keep the card within -40°C to 70°C operating range.
