Honeywell 51304718-200 Local Control Network Interface Card

Product Description

Honeywell 51304718-200 is the LCN Local Control Network Interface Card for Honeywell TDC3000 DCS system, the core communication board of TDC3000 distributed control system. As the interface unit for LCN token ring network, it connects operator stations, history modules and universal stations to the LCN control network to realize high-speed data exchange between system nodes. It supports A/B dual network redundant configuration with bumpless automatic switchover during faults to guarantee stable DCS network communication. Widely used in legacy TDC3000 distributed control systems in thermal power, chemical and refinery industries. It is an essential spare part for industrial plant overhaul and equipment maintenance.
