Emerson SE4302T01 KL3002X1-BA1 24V DC High Side CHARM – Functions & Applications
1. Key Functions
The Emerson SE4302T01 (KL3002X1-BA1) is a 24V DC High Side CHARM (Configurable Hardware Module) designed for DeltaV distributed control systems (DCS).
Its primary functions include:
High-Side Switching (Digital Output Control):
Provides 24V DC switching for actuators, solenoids, relays, and other field devices.
Supports high-side (source) switching, meaning it supplies +24V to the load (vs. low-side sinking).
Configurable I/O Flexibility:
Acts as a CHARM I/O module, allowing field-configurable digital outputs (DO) without rewiring.
Hot-swappable design for easy maintenance and replacement.
Protection & Diagnostics:
Includes short-circuit protection, overload detection, and open-load detection for safety.
LED indicators for real-time status monitoring (fault, power, communication).
Integration with DeltaV DCS:
Works seamlessly with DeltaV S-series I/O subsystems for process automation.
Supports FOUNDATION Fieldbus, HART, and PROFIBUS PA protocols (via DeltaV controllers).
2. Industrial Applications
The SE4302T01 High Side CHARM is widely used in industries requiring reliable digital output control:
Oil & Gas / Petrochemical:
Controls solenoid valves, shutdown systems, and emergency actuators in refineries.
Used in ESD (Emergency Shutdown) and safety instrumented systems (SIS).
Power Generation:
Manages turbine control valves, fuel shutoff systems, and boiler controls.
Pharmaceutical & Food Processing:
Automates batch processing, filling systems, and packaging machinery.
Water & Wastewater Treatment:
Operates pump control, chemical dosing valves, and filtration systems.
Manufacturing & Automotive:
Controls robotic arms, conveyor systems, and assembly line actuators.
3. Key Advantages
✔ Hot-swappable – Reduces downtime during maintenance.
✔ Field-configurable – No need for rewiring when changing I/O types.
✔ High reliability – Built-in diagnostics and fault protection.
✔ Seamless DeltaV integration – Works with Emerson’s DCS for process automation.
This module is ideal for critical control applications requiring robust, high-side switching in harsh industrial environments.
