Honeywell TC-PBFO01 ControlNet Repeater Adapter

Honeywell TC-PBFO01 Hazardous Location Repeater

Product Introduction

The Honeywell TC-PBFO01 serves as a dedicated ControlNet repeater adapter for hazardous environments. This unit operates with intrinsically safe power supply channels. It accepts two fiber module modules for flexible network expansion. You can use this adapter in areas with explosive gas risks. The TC-PBFO01 meets strict CENELEC and ATEX standards. Many industries rely on this model for safe and stable ControlNet communication.

Additionally, this device provides galvanic isolation between the TTL bus, power supply, and ControlNet. Therefore, signal integrity remains high even in noisy industrial settings. The communication rate reaches 5M bit/s, which supports real-time control data. For hazardous locations, the TC-PBFO01 delivers both safety and performance.

Technical Specifications

Electrical Parameters

The intrinsically safe power supply channel has an input voltage rating (Ui) of 9.5Vdc. Its input current (Ii) is limited to 1A. Inductance (Li) is negligible, while capacitance (Ci) stays at 120nF. Power consumption equals one power supply unit load. Total power dissipation reaches 8W.

For the internal TTL bus, the output voltage (Uo) is 5.4Vdc. Output current (Io) reaches 201mA, and output power (Po) is 1.09W. The allowable external inductance (Lo) is ≤0.45mH, with capacitance (Co) up to 71μF. Meanwhile, the external ControlNet bus also provides Uo = 5.4Vdc and Io = 201mA. This bus uses AC coupling with a high-pass filter at 900kHz.

Communication and Isolation

Communication runs at 5M bit/s, matching standard ControlNet requirements. Galvanic isolation follows DIN EN 50020 specifications. Isolation exists between TTL bus and power supply, TTL bus and ControlNet, and ControlNet and power supply. Therefore, ground loops and surges are minimized.

Fiber Module Capacity

The TC-PBFO01 holds up to two fiber module modules. This design allows redundant or extended fiber optic links. As a result, network reliability improves in remote or spread-out installations.

Mechanical and Environmental Ratings

Operating Conditions

Ambient temperature range spans from –20°C to 70°C (–4°F to 158°F). Storage temperature tolerates –20°C to 100°C (–4°F to 212°F). Maximum relative humidity is 95%, non-condensing. Pollution gas test meets Level G3 per ISA-S71.04-1985.

Shock resistance handles 15g peak for 11ms duration. Vibration test complies with IEC 68-2-6 at 2g from 10Hz to 500Hz. Protection class is IP20. For field installation, a separate housing with IP54 or better protection is required.

Physical Dimensions

Weight equals 0.319 kg (0.70 lb). Dimensions are 92 x 94 x 87 mm (3.6 x 3.7 x 3.4 inches). Wire size for power terminals accepts 12 AWG (4mm²) stranded maximum. Insulation diameter must not exceed 0.0469in (1.2mm). Use ControlNet cable type Belden 3092A. Refer to Honeywell's Experion Controller Specification for additional cable details.

Standards and Certifications

The Honeywell TC-PBFO01 conforms to DIN EN 50014:1992, DIN EN 50020:1994, and DIN EN 50284:1997. Climatic conditions follow DIN IEC 721. EMC compliance meets DIN EN 50081-2, DIN EN 50082-2, and NAMUR NE 21. CE conformity is TBD. CENELEC classification: II (1) 2G EEx ia/ib IIB/IIC T4. Agency certification includes DMT 99 ATEX E 036 X. This adapter is marked for all applicable directives.

Installation Guidelines

First, ensure the power supply is disconnected before wiring. Use only intrinsically safe circuits for the (+V, –V) channel. Next, secure the TC-PBFO01 inside an IP54 or better enclosure. Mount the device on a DIN rail or using the provided mounting holes. Then, connect the ControlNet cable (Belden 3092A) to the external bus port. Keep cable lengths within ControlNet specifications.

For fiber modules, insert them into the two available slots. Tighten the locking screws gently. After wiring, verify all connections. Apply power and check the status indicators. The TC-PBFO01 requires proper grounding to maintain intrinsic safety. Do not mix non-intrinsically safe circuits with these terminals.

Frequently Asked Questions (FAQ)

1. Can I use the TC-PBFO01 with standard ControlNet cables?
Yes, but Honeywell recommends Belden 3092A cable for full compliance. Other ControlNet-certified cables may work if they meet the 5M bit/s rate and impedance requirements.

2. What happens if I exceed the intrinsic safety values?
Exceeding Ui (9.5Vdc) or Ii (1A) will break the intrinsic safety barrier. This action creates an explosion risk in hazardous locations. Always verify your power supply matches the TC-PBFO01 specifications.

3. Do I need both fiber modules to operate the device?
No, the Honeywell TC-PBFO01 works with one fiber module. However, adding a second module provides redundancy or supports dual fiber optic links. For critical applications, we strongly recommend using two modules.

4. Is the device compatible with non-hazardous area installations?
Yes, you can also install the TC-PBFO01 in safe areas. But its advanced safety features make it more expensive than non-rated repeaters. Therefore, use it only where hazardous location certification is required.

5. How do I clean or maintain the TC-PBFO01 in the field?
Turn off power first. Wipe the housing with a dry, anti-static cloth. Do not use solvents or compressed air near fiber ports. Check cable connections every six months for corrosion or looseness.
