HONEYWELL 51304511-200 NIM Modem Communication Board

HONEYWELL 51304511-200 is a NIM Modem communication board designed for Honeywell TDC3000 DCS system. It serves as the core modem sub-board of the Network Interface Module, responsible for data encoding and decoding between the NIM unit and UCN universal control network.

This board supports Honeywell proprietary UCN communication protocol and provides stable high-speed data transmission for controllers and field devices on the UCN bus. It is widely used as spare replacement parts for maintenance and retrofit of legacy TDC3000 distributed control systems in petrochemical and power plants.
