Thomas-Conrad TC6142 ARC-CARD Network Interface Card

Description:

The Thomas-Conrad TC6142 ARC-CARD Network Card is used to provide ARCNET connectivity for IBM PC/XT-compatible industrial and commercial computer systems. Commonly installed in factory automation controllers, process control computers, manufacturing workstations, and legacy industrial networks, this 8-bit ISA adapter supports 2.5 Mbps ARCNET communication over 93-ohm RG62/U coaxial cable. Maintenance teams and system integrators use this network card for repair, retrofit, expansion, and replacement of legacy ARCNET-based control systems.

Applications:

The Thomas-Conrad TC6142 is designed for legacy ARCNET local area networks used in industrial automation, SCADA systems, machine control, laboratory equipment, manufacturing facilities, and process control environments. It enables reliable deterministic network communications between industrial computers and controllers, making it suitable for maintaining existing ARCNET infrastructure where ISA-based networking hardware is required.
