Product Overview
The Emerson SE4002S1T2B3 DeltaV S-series Discrete Output Card is an industrial I/O module used to transmit digital control commands from the DeltaV automation system to field devices.
In process control applications, discrete outputs are commonly used for executing simple but critical equipment actions, such as switching relays, controlling solenoid valves, activating alarms, and operating auxiliary devices. The SE4002S1T2B3 provides the interface between DeltaV control logic and external equipment, allowing automated strategies to directly influence field operations.
As a member of the DeltaV S-series I/O platform, this output card is installed within a modular DeltaV architecture and works with controllers, carriers, terminal blocks, and engineering software. It helps organize signal communication between the control system and field layer while supporting efficient system maintenance.
For troubleshooting, engineers generally check the complete control chain, including controller logic, I/O configuration, module diagnostics, field wiring, and the connected device, rather than focusing only on the output card.

Working Principle
The SE4002S1T2B3 works by receiving digital output commands from the DeltaV controller and converting those commands into electrical signals for external devices.
The signal process is:
Control Strategy → DeltaV Controller → SE4002S1T2B3 Output Card → Terminal Connection → Field Device
When the controller determines that a device action is required, it sends a digital command to the output card. The module changes the corresponding output channel state, allowing the connected equipment to respond.
Typical operations include:
- Energizing or de-energizing control circuits
- Activating solenoid valves
- Switching relays
- Controlling discrete actuators
- Triggering external status devices
The output card serves as the connection point between software-based automation decisions and physical equipment actions.
Role in a DeltaV Automation System
The Emerson SE4002S1T2B3 operates as the execution interface between DeltaV control logic and field equipment.
A typical system structure is:
Operator Station / Engineering Station → DeltaV Controller → Discrete Output Card → Field Device
The controller processes operating conditions and generates commands, while the output module delivers those commands to external devices.
In process industries, reliable digital output execution is essential because field equipment operation often depends on precise and timely control signals.
Industrial Applications
The Emerson SE4002S1T2B3 DeltaV S-series Discrete Output Card is commonly used in applications requiring digital equipment control.
| Application | Typical Use |
|---|---|
| Oil & Gas Facilities | Controlling valves and auxiliary equipment |
| Chemical Plants | Managing discrete process operations |
| Power Generation | Executing equipment switching commands |
| Water Treatment Systems | Operating pumps and control devices |
| Manufacturing Lines | Controlling machine functions |
| Process Automation Systems | Performing ON/OFF control tasks |
The specific application depends on the DeltaV system design and connected field devices.
Installation and Maintenance
Proper installation and system configuration are important for reliable operation.
Recommended maintenance procedures include:
- Confirm module model before installation
- Verify S-series carrier compatibility
- Check terminal wiring connections
- Confirm output channel assignments
- Review DeltaV I/O configuration
- Monitor module diagnostics
- Inspect installation environment
- Test field device response
- Record replacement information
When replacing an output module, engineers should verify the configuration and ensure the new card matches the original control strategy.

Technical FAQs
What role does the SE4002S1T2B3 play in a DeltaV control loop?
The module acts as the output execution point, transferring controller decisions to physical field devices.
What types of equipment can receive signals from this discrete output card?
Compatible applications include digital control devices such as relays, actuators, solenoid valves, and other ON/OFF equipment.
What should be checked if a field device does not react to an output command?
Engineers should inspect the control logic, module status, output configuration, wiring path, power supply, and field device condition.
Why is channel assignment verification necessary after module replacement?
Incorrect channel mapping can cause commands to be sent to the wrong equipment, so configuration verification is required before operation.
