The Emerson KL3003X1-LS1 DI 24VDC Dry Contact CHARM provides robust digital input capabilities for DeltaV distributed control systems, enabling reliable monitoring of discrete field devices including limit switches, pushbuttons, relay contacts, and proximity sensors. Engineered for industrial process automation, this low-side digital input module delivers dependable status detection in demanding manufacturing, oil & gas, chemical, and power generation environments.
Core Technical Specifications
- Input Type: 24VDC dry contact, low-side switching
- Signal Detection: Contact closure and opening detection
- CHARM Bus Power: +6.3VDC at 32mA
- Field Circuit Power: +24VDC at 10mA
- Terminal Block Key: 2C for proper CHARM identification
- Operating Temperature: -40°C to +70°C ambient
- System Compatibility: DeltaV v11.3.1+ with SD Plus, SX, SQ, MQ, MX, PK controllers
Environmental Ruggedness
Built to withstand harsh industrial conditions:
- Temperature Range: -40°C to +70°C for extreme climate installations
- Humidity Tolerance: 5% to 95% non-condensing for high-moisture environments
- Shock Resistance: 10g ½ sine wave for 11ms
- Vibration Resistance: 1mm peak-to-peak (2-13.2 Hz); 0.7g (13.2-150 Hz)
- Airborne Contaminants: ISA-S71.04-1985 Class G3 protection with conformal coating
Industrial Process Applications
Safety Interlock Monitoring: Monitor emergency stop buttons, safety gate switches, and guard door contacts in automated machinery and production lines. The dry contact input ensures fail-safe operation by detecting contact opening even during power loss conditions, critical for personnel safety systems.
Valve Position Feedback: Acquire limit switch signals from motor-operated valves (MOVs) and actuators to confirm fully open, fully closed, and intermediate positions. Dual limit switch monitoring enables precise valve sequencing in batch processes and prevents equipment damage from over-travel.
Pump & Motor Status Detection: Interface with auxiliary contacts from motor starters, circuit breakers, and overload relays to monitor running status, trip conditions, and fault states. Real-time status feedback enables automated restart sequences and reduces downtime in critical pumping applications.
Level Switch Monitoring: Connect to float switches, capacitance probes, and vibrating fork level detectors for high/low level alarms in tanks, vessels, and sumps. Multiple level switch inputs provide redundant protection against overfill and dry-run conditions.
Pressure & Temperature Switch Inputs: Monitor mechanical pressure switches and bimetallic temperature switches for backup protection and alarm generation. These hardwired safety inputs operate independently of transmitter electronics, providing defense-in-depth for critical process parameters.
Dry Contact Input Advantages
Low-side dry contact configuration offers distinct benefits:
- Universal Compatibility: Accepts signals from any voltage-free contact including relay outputs, switch contacts, and proximity sensor outputs
- Electrical Isolation: Dry contact operation eliminates ground loop issues and common mode voltage problems in multi-point installations
- Fail-Safe Operation: Contact opening detection ensures alarm generation even during field wiring failures or power loss
- Simple Wiring: Two-wire connection simplifies installation and reduces commissioning time compared to wet contact inputs
- Low Power Consumption: Minimal field circuit power (10mA) enables long cable runs without voltage drop concerns
Installation & System Integration
Designed for efficient deployment in DeltaV I/O architectures:
- Mounts on standard CHARM Baseplate with DIN rail installation
- Terminal Block Key 2C ensures correct CHARM type identification
- Auto-keying feature sets terminal block keys upon initial CHARM installation
- No user-serviceable parts - maintenance-free operation
- No calibration required - ready for immediate service
- Factory-tested for reliable long-term operation
Hazardous Area Installation Guidelines
Certified for classified location deployment:
- Refer to Document 12P5403 - DeltaV Electronic Marshalling Digital Automation System (CHARM I/O Subsystem) Zone 2 Installation Instructions
- Additional guidance in DeltaV S-series and CHARMs Hardware Installation Manual
- CHARM removal/insertion not allowed with system power energized unless area is non-hazardous
- All energy-limited nodes require I/O loop assessment before hot-swap operations
CHARM Compatibility & Keying
Intelligent keying system prevents installation errors:
- Terminal block keys auto-set upon initial CHARM installation to match module type
- To change CHARM type: remove terminal block and unlock/reset keys manually
- Keying system ensures only compatible CHARMs can be inserted into configured terminal blocks
- Prevents accidental insertion of wrong module type during maintenance activities
