Honeywell TC-RPFM01 ControlNet Fiber Module

The Honeywell TC-RPFM01, also cataloged as the TC-RPFM01 Fiber Media Converters, operates as a dedicated hardware component for high-speed optical ControlNet media conversion within Experion PKS controller networks.

Hardware Specifications

Galvanic Isolation & FOUNDATION Fieldbus / DCS Interface

The TC-RPFM01 module executes physical media conversion between standard electrical ControlNet signaling and optical light pulses across 62.5/125 micron multimode fiber at a 1300 nm wavelength. Galvanic separation per DIN EN 50 020 isolates the internal 30-pin TTL bus logic from external network circuits. This suppresses electrical noise transmission and common-mode potential shifts across distributed control architectures, protecting downstream DCS controllers and field bus interface gateways operating alongside FOUNDATION Fieldbus networks.

Frequently Asked Questions

Q: What optical power budget is available for field cable planning with the TC-RPFM01?

A: The module provides an optical power budget of 13.3 dB, supporting 1300 nm multimode fiber link distances up to 3 km.

Q: How is backplane power delivered to the TC-RPFM01 optical interface?

A: The module operates from an internal 5 VDC supply rail, drawing up to 4 A via the integrated 30-pin TTL bus connectors.

Q: What fiber optic connector style is required for field termination?

A: Field connections require standard ST connectors with either plastic or ceramic ferrules mated to 62.5/125 micron cable pairs.

Field Installation Guidelines

1. Mate the 30-pin male/female TTL bus connectors directly onto the mounting chassis header until firmly seated.
2. Clean optical ST connector ends using lint-free wipes and inspect fiber faces prior to insertion.
3. Connect 62.5/125 micron multimode fiber pairs to the ST optical ports, observing strict transmit and receive channel orientation.
4. Secure fiber patch cables within cabinet cable channels to prevent bending radii from exceeding manufacturer minimum limits.
