FISHER 38B5786X132 – Genuine Emerson OEM Single-Acting Direct Relay for DVC6200 & DVC6000 Positioners

The FISHER 38B5786X132 is an authentic OEM pneumatic relay assembly, engineered by Emerson as a critical performance component for the Fisher FIELDVUE™ DVC6200 and DVC6000 series digital valve controllers. Designed as a single-acting, direct-acting relay (Relay C), it serves as the pneumatic "muscle" that bridges the precision of digital control with the physical power required to drive spring-return diaphragm and cylinder actuators .

Far from a generic accessory, the 38B5786X132 is the factory-specified internal relay that threads directly into the DVC6200 housing. It receives a low-flow pilot signal from the I/P converter and proportionally amplifies it into a high-volume output (3-15 psi standard range), enabling rapid stroking and precise throttling of control valves in critical, high-cycle applications .

Product Type & Classification: A Note on Accuracy

Across the industrial supply sector, the FISHER 38B5786X132 is occasionally generalized as a "mounting kit" or "adapter bracket" . This is technically incorrect for the X132 suffix. Based on verified technical specifications and OEM parts matrices, the 38B5786X132 is definitively a PNEUMATIC RELAY ASSEMBLY. It includes the shroud, relay seal, and mounting screws, functioning as the active amplification stage inside the positioner. It is not a passive mechanical bracket .

This distinction is vital for procurement and maintenance accuracy. If you require a mechanical mounting kit for actuator-positioner integration, Fisher utilizes different 38B… prefix numbers tailored to specific yoke sizes.

Maintenance & Reliability Insights

The 38B5786X132 is a wear item in high-cycle applications (e.g., surge control, batch reactors). Emerson recommends proactive replacement when:

Valve stroking time increases by >25% from baseline.
Air bleed rate exceeds specification (typically >0.5 SCFM).
Step response tests show overshoot or excessive settling time.
ValveLink™ diagnostics flag "Relay/Diaphragm Degradation."

Ensure the precision and reliability of your critical control valves with genuine OEM components.
