- Communication Interface: Emerson system backplane/bus connection
Functional Features:
- Reliable Discrete Outputs: Built for consistent on/off actuation of field devices in demanding industrial environments
- Backplane Integration: Module logic is powered via the Emerson system backplane; field power is supplied externally for the outputs
- Status and Diagnostics: Channel and module status indication helps technicians pinpoint wiring issues quickly
- Channel Isolation Strategy: Designed to reduce cross-channel interference so a fault on one output does not propagate to adjacent channels
- Cabinet-Friendly Form Factor: Fits standard Emerson carriers and terminal bases, simplifying spares management and upgrades
- Serviceability: Supports online maintenance with minimal cabinet rework, reducing downtime during replacements
Application Scenarios:
- Power generation (boiler auxiliaries, dampers, fans, purge systems)
- Oil and gas (wellhead control, compressor skids, shutdown valves via solenoids)
- Chemicals and refining (pump starts, interlocks, alarm beacons)
- Water and wastewater (blower control, gate actuators, dosing skids)
- Pharmaceuticals and food and beverage (packaging lines, conveyors, reject gates)
- OEM machinery panels where Emerson controllers are specified
Material Composition:
- Industrial-grade electronic components with safety-rated output switching architecture
- Multi-layer PCB with discrete output driver circuitry
- Robust modular housing compatible with Emerson carrier and terminal base systems
Structural Features:
- Compact plug-in module footprint for Emerson I/O bases
- Standard cabinet depth compatibility
- Front-panel status and channel health LEDs
- Backplane connector for power and signal integration
- Terminal block assembly for field wiring connections
Working Principle:
The CE4002S1T2B5 receives control commands from the DeltaV controller through the system backplane. The onboard 32-bit RISC processor interprets these commands and drives the discrete output channels accordingly. Each output channel switches the externally supplied field power to activate or deactivate connected field devices. Channel isolation prevents fault propagation between outputs, and status LEDs provide real-time indication of channel states for rapid diagnostics.
Installation Requirements:
- Install in a clean, dry, ventilated control cabinet
- Maintain ambient temperature within 0°C to 55°C range
- Seat the module on its designated Emerson terminal base or carrier
- Ensure locking tabs are fully engaged
- Use appropriately rated conductors for field wiring
- Separate high-voltage and inductive load wiring from signal wiring to limit noise
- Provide a stable DC supply for outputs with fusing or breakers sized to the load
Usage Precautions:
- Interposing relays are recommended for large inductive devices
- Bond cabinet ground properly
- Consider transient suppression (flyback diodes or RC snubbers) for inductive loads to extend contact and module life
- Periodically tighten terminal screws and verify LED/channel status
- Review controller diagnostics on a routine basis
- The unit contains no user-serviceable parts and shall not be disassembled
