Product Overview

The TC-RPA002 (Part Number 97226074) is an authoritative modular repeater adapter designed for Honeywell Experion PKS and TDC 3000 systems. This module acts as the mechanical and electrical foundation for ControlNet signal extension, providing the interface required to host up to four additional repeater modules. Operating at a deterministic 5 Mbits/s data rate, the TC-RPA002 is a mechanical necessity for complex network topologies that exceed standard distance limitations or require media conversion (such as copper to fiber). Its rugged Class 2 (CL2) rated design and wide operating temperature range ensure trustworthy communication across large-scale industrial sites, including refineries and power generation facilities.

Detailed Technical Specifications

Installation and Engineering Application

• Network Extension: The TC-RPA002 is a mechanical necessity for ControlNet segments that require signal boosting. By adding repeater modules to this adapter, engineers can significantly extend the physical distance of the trunkline without losing data integrity.

• Module Mounting: The adapter supports up to four plug-in modules. Ensure that each repeater module is firmly seated and that the revision levels (e.g., C02) are compatible across the segment to maintain an authoritative network heartbeat.

• Power Distribution: Supply the unit with a stable 24VDC source. The unit is rated for up to 0.7A for internal operations, but the 7A CL2 rating must be respected when calculating the total load of the repeater stack to prevent thermal issues.

• Environmental Deployment: With a temperature rating up to +70 °C, the TC-RPA002 can be installed in remote field enclosures. For outdoor locations, ensure the enclosure provides adequate IP-rated protection to prevent moisture ingress.

• Media Conversion: When used with fiber optic repeater modules, the TC-RPA002 facilitates high-speed copper-to-fiber translation, which is the required expertise for linking disparate plant areas through high-EMI environments.

Technical FAQ

What is the primary function of the TC-RPA002 compared to a standard gateway?

Unlike a gateway that translates protocols, the TC-RPA002 is a physical layer repeater adapter. It maintains the deterministic 5 Mbits/s ControlNet signal while providing the infrastructure to extend the physical reach of the network or change the media type.

Can I mix different types of repeater modules on one adapter?

Yes. The TC-RPA002 is designed to host a variety of repeater modules, allowing for mixed-media segments (e.g., two copper ports and two fiber ports) on the same 24VDC powered base.

What does the Rev C02 indicate?

Revision C02 represents an updated hardware baseline with improved signal-to-noise ratios and internal power regulation compared to earlier revisions. It is recommended for new installations to ensure maximum trustworthiness in the communication backbone.
