Honeywell TC-RPA001 ControlNet Repeater Adapter

Honeywell TC-RPA001 Non-Hazardous Location Repeater

Product Introduction

The Honeywell TC-RPA001 serves as a ControlNet repeater adapter for standard industrial environments. This unit works in non-hazardous locations where explosion protection is not required. It accepts two fiber modules for network extension or redundancy. You can use this adapter to extend ControlNet segments over long distances. The TC-RPA001 provides reliable signal regeneration and electrical isolation.

Additionally, this device offers galvanic isolation between the TTL bus, power supply, and ControlNet bus. Therefore, it eliminates ground loops and reduces noise interference. The communication rate reaches 5M bit/s, which matches standard ControlNet timing requirements. For factory automation and process control, the TC-RPA001 delivers stable performance.

Technical Specifications

Power Requirements

The input voltage range spans from 20 to 35Vdc, with 24Vdc nominal. Voltage ripple must stay within 10% of the nominal value. Power consumption ranges from 230 to 400mA depending on load conditions. Power dissipation is TBD by Honeywell. One power supply unit load is required for proper operation.

Communication Rate and Bus Interfaces

Communication runs at 5M bit/s, fully compatible with ControlNet International Version 1.5. The internal TTL bus uses a vendor-specific protocol. The external ControlNet bus meets standard ControlNet specifications. Both buses work together seamlessly through the TC-RPA001.

Fiber Module Capacity

The Honeywell TC-RPA001 holds up to two fiber modules. Each module supports fiber optic cables for long-distance communication. You can install one module for a single link or two modules for redundant paths. This flexibility makes the TC-RPA001 suitable for ring or daisy-chain topologies.

Galvanic Isolation

Isolation follows DIN EN 50020 requirements. Three independent isolation barriers exist:

• TTL bus isolated from power supply

• TTL bus isolated from ControlNet

• ControlNet isolated from power supply

As a result, electrical noise on one bus does not affect the others. This feature protects connected controllers and I/O modules.

Mechanical and Environmental Ratings

Operating Conditions

Ambient temperature operates from –20°C to 70°C (–4°F to 158°F). Storage temperature ranges from –20°C to 100°C (–4°F to 212°F). Maximum relative humidity is 95%, non-condensing. These ratings make the TC-RPA001 suitable for most industrial control cabinets.

Mechanical Strength

Shock resistance reaches 15g peak for 11ms duration. Vibration test complies with IEC 68-2-6 at 2g from 10Hz to 500Hz. Therefore, the device withstands typical factory floor vibrations. Protection class is not specified, so install it inside an enclosure for best results.

Physical Dimensions

Weight equals 0.226 kg (0.50 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 copper maximum. Insulation diameter must not exceed 0.0469in (1.2mm). Use Belden 3092A cable for ControlNet connections. Refer to the ControlNet specification guide for detailed cable planning.

Standards and Compliance

The Honeywell TC-RPA001 conforms to climatic conditions per DIN IEC 721. EMC compliance meets DIN EN 50081-2, DIN EN 50082-2, and NAMUR NE 21. CE conformity is confirmed for Europe. The device is marked for all applicable directives. Unlike the hazardous-location version (TC-PBFO01), the TC-RPA001 carries no ATEX certification.

Installation Guidelines

First, disconnect all power before handling the TC-RPA001. Mount the device on a DIN rail inside a control cabinet. Ensure adequate ventilation around the unit. Next, connect the 24Vdc power supply to the +V and –V terminals. Verify the voltage stays between 20V and 35Vdc. Then, attach the ControlNet cable (Belden 3092A) to the external bus port.

For fiber optic connections, insert the fiber modules into the two available slots. Push each module firmly until it clicks. Secure the fiber cables with the module's locking mechanism. Finally, power up the system and check the status LEDs. The TC-RPA001 requires no software configuration for basic operation.

Frequently Asked Questions (FAQ)

1. Can I use the TC-RPA001 in a hazardous location?
No, the Honeywell TC-RPA001 is only rated for non-hazardous locations. For explosive atmospheres, use the TC-PBFO01 model instead. The TC-RPA001 lacks intrinsic safety barriers and ATEX certification.

2. What is the maximum cable length between two repeaters?
ControlNet specifications allow up to 1000 meters (3280 feet) per segment using Belden 3092A cable. The TC-RPA001 regenerates the signal, so you can extend networks far beyond this limit by chaining multiple repeaters.

3. Do I need to configure the TC-RPA001 with software?
No, the TC-RPA001 is a plug-and-play device. It requires no IP addresses, switches, or programming. Simply connect power and the ControlNet cables, and it works immediately.

4. How do I know if the device is working properly?
The Honeywell TC-RPA001 has built-in status LEDs. A green power LED indicates correct voltage. Blinking activity LEDs show data transmission on each fiber port. No LEDs or red lights suggest a power or wiring issue.

5. Can I mix fiber modules from different manufacturers?
Honeywell recommends using only Honeywell-approved fiber modules with the TC-RPA001. Third-party modules may not meet the electrical or optical specifications. Using non-approved modules could cause communication errors or damage the repeater.
