TC-PMFO01 Honeywell ControlNet Fiber Module for Hazardous Locations
The TC-PMFO01 is a Honeywell ControlNet fiber module built for hazardous locations. It links ControlNet networks over 62.5/125 micron fiber optic cable. The module supports one fiber module plus one repeater adapter module. Power comes through the repeater adapter module. It fits CENELEC II (1) 2G EEx ia/ib IIB/IIC T4 areas. The ST termination accepts plastic or ceramic connectors. The 1300nm wavelength delivers a 13.3dB power budget. Transmission reaches up to 3km (9,842ft) at a 5M bit/s communication rate. Galvanic isolation separates the TTL bus from ControlNet. Use it for long-distance links, noisy plants, and hazardous zones.

Installation Guide
- Mount the module in a IP54 or better housing for field use.
- Keep the ambient temperature between –20°C and 70°C.
- Fit the module into the repeater adapter module. Power comes through that adapter.
- Plug the 30-pin male bus connector into the output side.
- Plug the 30-pin female bus connector into the input side.
- Clean the ST connectors before you attach the fiber cable.
- Check the 13.3dB power budget against total link loss.
- Keep fiber bends wide. Do not twist or pinch the cable.
Commissioning and Maintenance
- Verify link status on the ControlNet segment after power-up.
- Measure optical receive power with a fiber meter.
- Re-seat ST connectors if the link drops.
- Inspect connectors for dust during routine service.
- Keep spare adapters on site for fast swap-out.
- Log link margin values to track aging.
Compatibility
- Works with ControlNet networks on 62.5/125 micron fiber.
- Accepts ST plastic or ceramic connectors.
- Pairs with one repeater adapter module for power.
- Fits Honeywell ControlNet systems that use this fiber module family.
Diagnostics
- Link status shows on the host ControlNet segment.
- Optical power readings reveal cable or connector loss.
- A 13.3dB budget check spots weak links early.
- Galvanic isolation blocks ground loops between TTL bus and ControlNet.
Typical Applications
- Long ControlNet runs in hazardous process areas.
- Fiber links across high-voltage or noisy plant sections.
- Repeater links between distant ControlNet segments.
- Chemical, oil and gas, and power plants with ATEX zones.
