DAC8864BT is a BTL certified logic controller that meets the BACnet B-AAC level of advanced programmable and independent operation. It is often used to monitor and control the mechanical and electrical equipment in the building, such as large air-conditioning boxes, water pumps, fans, and exhaust cabinets. . Waiting for equipment. It uses a 32-bit microprocessor to manufacture super powerful functions and superior performance, with a communication rate of up to 76,800 BPS and a transmission distance of up to 1,200 meters. DAC8864BT has programmable control functions, and supports BACnet standard objects such as calendars, timetables, notification types, and alarm event registration; it has physical digital input points (BI), analog input points (AI), digital output points (BO) and Analog output point (AO); It has an EIMnet communication port that can be connected to 12 EIM series expansion modules, allowing you to flexibly combine to meet the point needs of different occasions; It has an LCD screen touch panel, which is convenient for users to set, operate, and Monitor and check equipment operating status and information. DAC8864BT adopts the international BACnet communication protocol standard, which can be integrated, interconnected and mutually controlled with any brand of BACnet monitoring system. It is definitely the best equipment for you to build a monitoring system.
