The Honeywell XC5010C is a computer module designed for building management control and monitoring systems. The unit utilizes a Toshiba TMP93CS41F 16-bit microprocessor and operates within the Excel 500/600 control system architecture. It provides freely programmable direct digital control (DDC) functions and energy management features for medium-sized facilities such as offices, schools, and hospitals. The device features an open LONWORKS bus interface using an FTT-10A Free Topology Transceiver with a Neuron chip 3120, along with a C-bus communication port, an RS 232 port for MMI, modem, or terminal adapters, and a gold capacitor data buffer supporting a 72-hour memory backup.
