Overview
The ABB CL-LDD.K display module (part number 1SVR440839R4400) is a dedicated display accessory for ABB’s CL range industrial control relays. This display module features a backlit 132×64 pixel graphic display with keypad, providing clear, readable operator feedback in control cabinets and switchgear environments. The module operates at 24 V DC rated voltage and integrates seamlessly with CL logic relay base modules to create complete automation visualization systems.
Key Features
- Backlit 132×64 pixel graphic display with integrated keypad for operator interaction
- Rated operational voltage: 24 V DC
- Compact dimensions: 86.5 mm width × 21.5 mm depth × 86.5 mm height; Weight: 0.13 kg
- IP65 rating for protection in harsh industrial environments
- Designed as part of the CL range expandable logic relay system
- Compliant with EU Directive 2011/65/EU (RoHS)
Technical Specifications
The CL-LDD.K is engineered for installation on CL logic relay base modules. Certifications include CE Declaration of Conformity (1SVD982004-0001), CSA Certificate (CSA_1875990), and DNV GL Certificate (DNV_GL_TAA000018Z). The graphic display delivers crisp rendering of process data, alarms, and operator prompts, with the integrated keypad enabling parameter adjustment and system navigation without external terminals.
Typical Applications
- Industrial automation and process control systems requiring real-time operator feedback
- Manufacturing machine HMI (Human-Machine Interface) applications
- HVAC and building automation visualization modules
- Safety relay and logic control system monitoring
- Switchgear cabinet and control panel operator interfaces
- Distributed automation nodes in networked CL-NET systems
Compatibility & Replacements
The ABB CL-LDD.K is part of the CL range modular system and mounts directly to compatible CL base modules (CL-LDC.LDC2, CL-LDC.LAC2, CL-LDC.LNDC2, CL-LDC.LNAC2). A variant without keypad (CL-LDD.XK, 1SVR440839R4500) is available for applications requiring display-only operation. Remote display modules with extended cable lengths (CL-LDC.S..) are also available for installations requiring separation of display from the logic base unit. Always verify base module power supply voltage compatibility (AC or DC) before ordering.
