BELDEN 9844 4 PAIR MODBUS DMX
Belden 9844 is a high-capacity, four-pair shielded twisted pair cable engineered for complex RS-485, Modbus, and industrial data communication networks. By grouping four individual 24 AWG pairs under a single, robust, dual-layer shield, it provides an efficient solution for consolidating multiple control signals into a single cable run.
Product Description
Belden 9844 offers the highest pair-count in this specific series, making it the ideal choice for dense wiring environments where space is at a premium and multiple channels of information must be processed simultaneously.
Key Technical Specifications
Conductor Construction: Four pairs of 24 AWG (7x32) stranded tinned copper conductors. The stranded construction facilitates easier handling and routing in tight control cabinets or through conduit systems.
Dielectric/Insulation: Polyethylene (PE) insulation is utilized to maintain low capacitance, ensuring that the 120-Ohm characteristic impedance remains stable across all four pairs, which is vital for long-distance RS-485 data integrity.
Dual-Shielding Architecture:
Beldfoil® Shield: 100% coverage aluminum/polyester foil provides comprehensive protection against high-frequency electromagnetic interference.
Tinned Copper Braid: 90% coverage tinned copper braid provides essential low-frequency interference shielding and contributes to the overall mechanical strength and durability of the cable.
Outer Jacket: Durable, flame-retardant PVC (CM rated) jacket designed to withstand typical industrial environmental stress.
Primary Applications
High-Density Industrial Control: Ideal for systems requiring four distinct serial data paths, such as complex Modbus multi-drop networks or centralized PLC/SCADA architecture.
Advanced Lighting and Stage Control: Frequently used in professional DMX512 setups that require routing multiple DMX universes through a single infrastructure.
Building Automation: Excellent for centralized control systems where multiple sensor or actuator loops are bundled to minimize cabling complexity.
