Engineering Advantages
-
Precision Voltage Regulation: The RH926KQ offers an adjustable output range between 23V and 25V DC. This flexibility allows engineers to compensate for voltage drops across long cable runs, ensuring that distant field instruments receive exactly 24V DC for optimal performance.
-
Extended Reach Integration: Each RH926KQ comes equipped with an 84-inch (~2.13 meter) integrated cable. This generous length simplifies routing within high-density control cabinets and allows for versatile placement away from heat-generating components.
-
Superior Noise Suppression: The module employs high-efficiency regulation circuitry that filters out electrical ripple and noise. This clean power output protects sensitive digital communication signals on the fieldbus from interference, reducing error rates in data transmission.
-
Industrial-Grade Resilience: Engineered for harsh process areas, the RH926KQ resists dust and moisture ingress. Its rugged housing withstands the vibrations typical of industrial machinery environments, ensuring continuous power delivery where standard power supplies fail.
-
Simplified Fieldbus Distribution: This module streamlines the power architecture of a DCS node by consolidating power distribution for multiple fieldbus devices. This reduction in individual power wiring points minimizes potential failure locations and simplifies troubleshooting.
FAQs
Can I adjust the output voltage of the RH926KQ in the field?
Yes. The RH926KQ allows for fine-tuning of the output voltage between 23V and 25V DC. This feature helps you maintain a steady 24V at the instrument terminals regardless of the resistance encountered in long fieldbus segments.
Is this module compatible with non-Foxboro fieldbus devices?
While Foxboro designed the RH926KQ for the I/A Series, it provides a standard regulated 24V DC output suitable for any fieldbus device (transmitters, sensors, etc.) that requires a stable 24V power source within its current rating.
What is the benefit of the integrated 84-inch cable?
The pre-installed 84-inch cable reduces the need for additional terminal connections and custom wiring during installation. It provides enough length to reach remote segments of a control rack while maintaining the factory-sealed integrity of the power connection.
How do I know this unit is brand new?
Every Foxboro RH926KQ we ship is 100% brand new and original. Each module arrives in its original manufacturer packaging with a full factory-tested report and a 12-month warranty, guaranteeing it has never been deployed or refurbished.
