Honeywell 620-0081 Data Hiway Interface Module

The Honeywell 620-0081 Data Hiway Interface Module is a communication interface module designed to connect IPC 620 programmable controllers to Honeywell Data Hiway networks used in TDC 2000 and TDC 3000 distributed control systems. It provides protocol conversion and network access between PLC-based control platforms and higher-level DCS infrastructure while supporting redundant communication paths for improved system availability.

Product Specifications

Data Hiway Communication Function

The 620-0081 serves as the communication bridge between IPC 620 controllers and Honeywell Data Hiway networks. Through this interface, controller data, status information, alarms, and process variables can be exchanged with supervisory systems operating within TDC architectures.

The module enables PLC-based control applications to participate in larger distributed control environments without requiring changes to the native controller operation.

Network Architecture Support

The interface supports the proprietary Honeywell Data Hiway communication protocol used throughout TDC 2000 and TDC 3000 systems. This allows process information generated by IPC 620 controllers to be shared with operator stations, historical databases, and other networked control resources.

By providing protocol-level integration, the module extends the visibility of PLC-controlled processes into the plant-wide control network.

Redundant Communication Paths

Two BNC coaxial connections are provided to support redundant A and B communication channels. This arrangement allows communication to continue in the event of a cable or network path fault, depending on the overall network architecture.

Redundant network connectivity is particularly valuable in critical process applications where sustained controller-to-DCS communications are required.

Communication Performance

The module supports data transmission at 250 kbps over standard Honeywell coaxial network infrastructure. With suitable line drivers and network amplification equipment, communication distances can extend to 6,100 m (20,000 ft).

These capabilities allow deployment across large industrial facilities where controllers may be located significant distances from central control rooms.

Installation Characteristics

The 620-0081 is supplied as a single-slot plug-in card for IPC 620 system chassis installations. Operating power is supplied from a 24 VDC source, with a maximum power consumption of 10.5 W.

Its compact form factor allows integration into existing controller racks without requiring dedicated external communication hardware.

Environmental Specifications

The module is rated for operation between 0 deg C and 60 deg C and can be stored between -40 deg C and +85 deg C. Relative humidity ratings of 5% to 95% non-condensing support installation in typical industrial control environments when mounted within suitable enclosures.
