TC-RPA001 Honeywell ControlNet Repeater Adapter for Non-Hazardous Locations
The Honeywell TC-RPA001 is a ControlNet repeater adapter. It extends ControlNet segments in non-hazardous areas. The unit supports two fiber modules. It uses a 24Vdc nominal supply. The external bus follows ControlNet International Version 1.5. The communication rate reaches 5M bit/s. Galvanic isolation separates the TTL bus, the power supply, and ControlNet. This design protects signal integrity in dense industrial networks. The adapter suits legacy ControlNet systems that need reliable segment extension.

Installation Guide
- Mount the adapter on a stable panel. Keep airflow clear around the housing.
- Connect 20 to 35Vdc to the power terminals. Observe polarity.
- Use Belden 3092A cable for ControlNet links.
- Keep wire size at 12 AWG or smaller. Limit insulation to 1.2mm.
- Verify isolation between TTL bus, power, and ControlNet before power-up.
- Confirm the 5M bit/s rate matches the network plan.
Commissioning and Maintenance
Start with a visual check of terminals and fiber modules. Apply 24Vdc nominal power. Watch for stable current draw within 230 to 400mA. Run a segment test at 5M bit/s. The galvanic isolation limits ground-loop faults. Routine maintenance needs little effort. Inspect fiber connectors for dust. Re-tighten power terminals at planned intervals. The wide -20°C to 70°C range reduces seasonal service calls.
Compatibility Notes
The adapter follows ControlNet International Version 1.5. It works with standard ControlNet cable such as Belden 3092A. The external bus is intrinsically safe rated per the source data. Use it only in non-hazardous locations. The internal TTL bus is vendor-specific. Match fiber modules to the network plan. Confirm host controller firmware supports the repeater role.
Certifications and Standards
- CE Conformity (Europe)
- EMC per DIN EN 50081-2 and DIN EN 50082-2
- NAMUR NE 21 EMC guidance
- Climatic conditions per DIN IEC 721
- Marked for all applicable directives
Diagnostic Capability
The adapter supports segment-level checks at 5M bit/s. Isolation barriers help isolate ground faults. Stable current draw within 230 to 400mA signals healthy power. Technicians can verify bus health with standard ControlNet tools. This shortens fault finding in legacy lines.
Typical Applications
