EMERSON KJ3204X1-BA1 (Digital) Output Module
EMERSON KJ3204X1-BA1
1. Overview
KJ3204X1‑BA1 is a discrete (digital) output module for the Emerson DeltaV control system, belonging to the Series 2 family. Each card provides 32 independent digital outputs and is equipped with a terminal block, suitable for the on-off control of field devices (such as valves, relays, indicator lights, etc.). This module is commonly used in process automation systems for oil, chemical, electric power, pharmaceutical and other industries, and can achieve high-speed and reliable discrete signal output in the DeltaV DCS environment.
2. Key Specifications

| Power Supply | 24 V DC (powered by DeltaV system) |
| Terminal Block | 32-channel terminal block for easy on-site wiring |
| Operating Temperature | –20 °C ~ +55 °C (industrial grade) |
| Protection Level | IP20 (for indoor installation) |
| Compatible Platforms | DeltaV Series 2 controllers (e.g., VE4000, VE4001 series) |
| Certifications | CE, UL, IEC 61508 (functional safety) |
| Dimensions | Standard 2-U rack card (approximately 88 mm × 88 mm) |
| Weight | ≈ 0.8 kg |
3. Product Features
- 32-channel High-density Output: A single installation can meet the needs of large-scale discrete control.
- Modular Design: Multiple cards can be flexibly combined on the same rack to achieve expansions of 64, 96, 128 channels, etc.
- Quick Terminal Wiring: The terminal block adopts screw-type crimping, making on-site wiring simple and reliable.
- Reliability: Uses industrial-grade components and complies with the IEC 61508 functional safety standard, suitable for critical processes.
- Full Compatibility with DeltaV: Supports DeltaV configuration tools (DeltaV Config, DeltaV Explorer) to achieve unified engineering management.
- Diagnostic Function: The module performs self-tests and reports fault status through the DeltaV system, facilitating maintenance.
4. Structure and Composition
- Card Body: A metal rack card with a built-in 32-channel relay output drive circuit.
- Terminal Block: Located at the front of the card body, providing 32 screw crimp terminals.
- Power Interface: A 24 V DC power socket, shared by power supply and signals.
- Indicator Lights: Status indicator lights (power, fault, communication) are located on the side of the card body.
- Connection Cable: A high-speed digital interface for communication with the backplane bus (VE4000/VE4001).
5. Typical Application Fields
| Industry | Specific Applications |
|---|---|
| Oil & Gas | Wellhead valves, pump station switches, emergency shutdown circuits |
| Chemical | Reactor valves, cooling systems, alarm lights |
| Electric Power | Generator set switching, power distribution cabinet relays, protection circuits |
| Pharmaceutical | Cleanroom valves, batch control, warning lights |
| Water Treatment | Pump station start-stop, valve control, leakage alarms |
| Food & Beverage | Production line valves, packaging equipment control, quality alarms |
6. Installation and Maintenance Points
Pre-installation Inspection
- Confirm that the rack space meets the dimensions of the 2-U card.
- Check whether the power supply voltage (24 V DC) and grounding comply with specifications.
Mechanical Installation
- Insert the card into the corresponding slot of the VE4000/VE4001 backplane, ensuring that the card body is clipped in place.
- Use screws to fix the terminal block to prevent loosening due to vibration.
Electrical Wiring
- Crimp the on-site relay wires to the corresponding terminals according to the terminal block markings (1-32).
- For 24 V DC and 120 V AC outputs, use the corresponding terminal strips respectively (the module provides optional configurations).
System Configuration
- Add the module in DeltaV Config and assign an I/O address.
- Set the output logic (normally open/normally closed, delay, pulse, etc.).
Commissioning and Verification
- Check the module status lights through DeltaV Explorer to confirm no faults.
- Use the manual mode to test outputs channel by channel and verify the closing/opening of relays.
Daily Maintenance
- Regularly check the terminal crimping to prevent loosening or corrosion.
- Monitor the module self-test report and replace faulty cards in a timely manner.
- In high-temperature or humid environments, it is recommended to install protective covers or ventilation devices.
