MTL RELCOM F802 Redundant Fieldbus Power System – RELCOM Fieldbus Power Series
In a continuous process plant—whether it’s an oil refinery, chemical reactor, or offshore platform—a single point of power failure on a FOUNDATION Fieldbus H1 segment can cascade into unplanned shutdowns, lost production, and costly emergency maintenance. Without a dedicated redundant power conditioner, every field device on that segment becomes vulnerable: flow transmitters go blind, control valves freeze in position, and operators lose visibility at the worst possible moment. The MTL RELCOM F802 exists precisely to eliminate that risk.
The RELCOM F802 is MTL Instruments’ dual-redundant fieldbus power conditioner engineered for FOUNDATION Fieldbus H1 and PROFIBUS PA segments. Within the globally trusted RELCOM series—MTL’s dedicated line of fieldbus infrastructure components—the F802 occupies the critical tier of high-availability power supply, delivering seamless active redundancy that meets the stringent demands of SIL-rated process control environments. It is deployed across refineries, LNG terminals, pharmaceutical plants, and water treatment facilities on every continent.

Key Features & Benefits
- True Active Redundancy: Both power modules operate simultaneously; if one fails, the other sustains the segment without interruption or manual switchover.
- Signal Integrity Protection: High-impedance design prevents power supply noise from corrupting fieldbus communication signals.
- Hot-Swap Capability: Failed modules can be replaced under live conditions, eliminating the need for segment shutdown during maintenance.
- Compact DIN Rail Form Factor: Optimized for marshalling cabinet and junction box integration in space-constrained installations.
- Wide Industrial Compatibility: Supports all major FOUNDATION Fieldbus H1 and PROFIBUS PA field devices from leading vendors (Emerson, Yokogawa, ABB, Endress+Hauser, etc.).
- Reduced Lifecycle Cost: Eliminates segment downtime events, dramatically reducing the total cost of ownership versus non-redundant alternatives.
Industry & Equipment Applications
- Oil & Gas: Upstream wellhead control, midstream pipeline monitoring, downstream refinery DCS integration

Frequently Asked Questions
Q: What is the difference between the MTL F802 and a standard (non-redundant) fieldbus power supply?
A: The F802 uses two active power modules operating in parallel. If one module fails, the other continues to power the segment without any interruption. A standard single-module supply would cause a complete segment outage on failure.
Q: Is the RELCOM F802 compatible with PROFIBUS PA as well as FOUNDATION Fieldbus H1?
A: Yes. The F802 is designed to comply with IEC 61158-2 physical layer requirements, which are shared by both FOUNDATION Fieldbus H1 and PROFIBUS PA protocols.
Q: Can I replace a failed module while the segment is live?
A: Yes. The hot-swap design allows module replacement under energized conditions, provided your site safety procedures permit live work on the cabinet.
Q: What DCS systems has the F802 been validated with?
A: The F802 has been used with Emerson DeltaV, Honeywell Experion PKS, Yokogawa CENTUM VP, and ABB 800xA, among others. Contact us for specific compatibility documentation.
Q: How do I request a datasheet or certificate of conformity?
A: Email [email protected] with your order reference or inquiry number and we will provide the full documentation package.
