Product Details
The Foxboro RH926KQ, also cataloged as the RH926KQ Power Supply Output Cable Assembly, operates as a dedicated hardware component for 24 VDC power distribution within Foxboro I/A Series DCS networks. Spanning a length of 84 inches (2.13 meters), this industrial-grade multi-conductor assembly routes primary DC power outputs directly from system power supply units to target baseplate backplanes and field enclosure components.

DCS Process Control and Channel Isolation
The Foxboro RH926KQ cable delivers low-impedance 24 VDC auxiliary power to DCS baseplates and field termination assemblies while preserving signal integrity across connected analog subsystems. Heavy-duty conductor shielding minimizes high-frequency noise injection onto parallel control buses, supporting uncorrupted signal conditioning for 4-20 mA HART loop protocol instruments and fieldbus interface cards. Physical spacing within the industrial jacket prevents potential cross-talk and common-mode noise coupling between power distribution rails and sensitive channel-to-channel isolation circuitry in adjacent I/O modules.
Frequently Asked Questions
Q: Can the RH926KQ power cable be disconnected while the system baseplate is actively powered?
A: Disconnecting the RH926KQ cable under load removes the primary 24 VDC supply rail, causing an immediate shutdown of modules residing on that baseplate segment unless a redundant power assembly is connected.
Q: What insulation standards apply to the RH926KQ cable for industrial enclosure routing?
A: The high-durability polymer insulation is rated for 24 VDC continuous operation and provides thermal and flame-retardant resistance suitable for standard control cabinet wiring runs.
Field Installation Guidelines
- Verify that the primary power supply source is de-energized prior to connecting or disconnecting the RH926KQ assembly.
- Route the 84-inch cable along cabinet wire ducts, avoiding sharp metal edges and maintaining recommended minimum bend radii to prevent conductor strain.
- Align keyed cable connectors with the mating power output headers on the Foxboro power supply unit and baseplate backplane.
- Secure locking latches or retention screws on both terminal ends to prevent connection loosening from industrial vibration.

Tech & Buying Guide
Master Acceptance Testing: Understanding FAT and SAT in Industrial Control Systems
Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) serve as critical quality assurance gateways in complex industrial control systems. Both procedures verify that programmable logic controllers (PLCs), distributed control systems (DCS), and associated field devices meet strict functional specifications. However, executing these tests effectively requires clear delineation between off-site staging and final field commissioning.
Industrial Networking Essentials: Demystifying Hubs, Switches, and Routers in Control Systems
Industrial automation relies heavily on robust networking infrastructure to connect programmable logic controllers (PLCs), distributed control systems (DCS), and human-machine interfaces (HMIs). Modern factory automation environments generate vast amounts of real-time operational data across deterministic networks. Understanding the structural differences between hubs, switches, and routers ensures optimal traffic segmentation, minimizes latency, and maintains high network availability.
Safety Relays in Industrial Automation: Fundamentals, Design Standards, and Fail-Safe Architecture
Safety relays form the bedrock of functional safety in modern factory automation, preventing catastrophic equipment failure and protecting plant personnel. While standard electromechanical relays handle basic load switching, they lack the redundant diagnostics required for high-risk industrial environments. Modern industrial automation platforms—including programmable logic controllers (PLCs) and distributed control systems (DCS)—rely on specialized safety relays to monitor field devices and isolate hazards instantly.
