TC-RPFM01 Honeywell ControlNet Fiber Module

Overview

The Honeywell TC-RPFM01, also cataloged as the TC-RPFM01 ControlNet Fiber Module, provides fiber-optic communication for ControlNet networks in non-hazardous locations. It supports a 5 Mbit/s communication rate over 62.5/125 micron fiber, with ST connectors, a 1300 nm optical wavelength, and a specified optical power budget of 13.3 dB. The module operates with a separate Repeater Adapter module, which supplies its power.

Hardware Specifications

ControlNet Fiber-Optic Communication

The TC-RPFM01 converts the supported ControlNet communication path to a fiber-optic link through its associated repeater hardware. The specified optical interface uses 62.5/125 micron fiber and ST termination at 1300 nm.

The maximum stated transmission distance is 3 km, subject to the installed optical link meeting the module’s optical power budget of 13.3 dB. Actual link performance depends on fiber attenuation, connector losses, splices, and the connected network equipment.

The module uses a vendor-specific 30-pin TTL bus interface. Its power consumption and dissipation are assigned to the Repeater Adapter module, so a separate module-level power figure cannot be established from the supplied specifications.

Frequently Asked Questions

Q: What is the maximum fiber-optic transmission distance of the TC-RPFM01?

A: The specified maximum distance is 3 km (9,842 ft). The installed fiber link must remain within the 13.3 dB optical power budget.

Q: Does the TC-RPFM01 require a separate power supply connection?

A: The module receives power through the Repeater Adapter module. Its power consumption and power dissipation are included with that adapter.

Q: Which fiber type and connectors does the TC-RPFM01 support?

A: The specified fiber type is 62.5/125 micron, with ST termination using plastic or ceramic connectors. The optical wavelength is 1300 nm.

Field Installation Guidelines

• Confirm that the installation location is non-hazardous and that the module is compatible with the intended ControlNet repeater configuration.
• Install the TC-RPFM01 with its designated Repeater Adapter module and verify the mechanical fit and 30-pin bus connections before energizing the assembly.
• Inspect fiber ends and ST connectors for contamination or damage. Clean and connect them using appropriate fiber-optic handling procedures.
• Route fiber-optic cables separately from sources of mechanical stress. Observe the cable manufacturer’s minimum bend radius and pulling-force limits.
• Check the optical link budget against the installed fiber length, connector losses, and any splice losses before commissioning.
• Keep the operating environment within -20 to 70 deg C and below 95% relative humidity, non-condensing.
• Verify ControlNet communication after installation. Do not infer hot-swap support or a specific redundancy switching time from the supplied specifications.
