Honeywell PBA455971-002 Ethernet Module

Honeywell PBA455971-002 Ethernet Module The Honeywell PBA455971-002, also cataloged as the PBA455971-003 LAN controller, serves as the primary industrial network interface card utilized to execute TCP/IP communication across Honeywell Multibus and PC/AT system platforms. Hardware Specifications Parameter Specification Model PBA455971-002 / -003 Brand Honeywell Origin USA Weight 330 g to 450 g (0.73 lbs to 1.0 lbs) Dimensions Standard NIC form factor Operating Temp -25 deg C to +60 deg C Storage Temp -40 deg C to +70 deg C Bus Interface Intel Multibus (IEEE-796), PC/AT Data Rate 10/100 Mbps Ethernet Protocol Support TCP/IP, legacy protocols Profinet / EtherNet/IP Deterministic Networks The module supports deterministic Ethernet communication at 10/100 Mbps, ensuring compatibility with legacy Honeywell controllers and modern supervisory systems. Integration with Intel Multibus architecture allows direct backplane bus communication velocity licensing, while PC/AT compatibility extends usability across hybrid installations. Deterministic packet handling ensures predictable latency for industrial control loops. Frequently Asked Questions Q: Can the PBA455971-002 be installed in both Multibus and PC/AT systems? A: Yes, the card is designed for dual compatibility, supporting IEEE-796 Multibus and PC/AT slots. Q: What is the recommended procedure for firmware flash compatibility? A: Firmware is fixed; compatibility is maintained through hardware design. No field flash upgrades are supported. Q: Does the module support redundant Ethernet links? A: Redundancy is achieved at the system level; the card itself provides single-port Ethernet connectivity. Field Installation Guidelines Insert the module into the designated Multibus or PC/AT slot with firm mechanical engagement. Ensure shielded Ethernet cabling is grounded at a single point to minimize cross-talk. Maintain separation between Ethernet cabling and high-voltage wiring. Observe ambient temperature limits; ventilation is required for operation up to 60 deg C. Verify link LEDs during commissioning to confirm communication status.
