HT500 environmental data acquisition unit, also known as the auxiliary control panel, environmental data processing unit, a smart collector. Is the base for the communications industry and the power industry and other internal power substation, environmental, security and other monitoring and control of the design and production of a product. Environmental data acquisition unit is RFID, sensors and a variety of power or electrical equipment for networking, to provide users with the environment, video, security, fire alarm and fire protection, heating, ventilation, lighting and air conditioning, fans, pumps and other intelligent terminal equipment control . Particularly suitable for applications in base stations, substations, railway room, bank vaults and other places need to focus on monitoring. HT500 environmental data acquisition unit features: 1, to achieve power, UPS and other power equipment, as well as a host of monitoring and management of Fire: The serial data and network data conversion between IP packet, thus completing the remote management, serial port expansion, the traditional serial device networking, serial devices communicate with each other and other functions. 2, can access eight-way switch (2U device HT502 expanded to 24 channels), to achieve the electronic fence, flooding, infrared, smoke, burglar alarm monitoring and other functions. 3, can access 6 analog to realize temperature, humidity, wind speed, level, SF6 and other analog access. Supports 8-channel relay (2U device HT502 expanded to 24 channels) output, to achieve the lights, fans, pumps and other equipment control functions. 4, through the air conditioning remote control (connected to RS485 interface), to achieve the air conditioning on, off, cooling, heating, ventilation and temperature control and other functions. 5, all the way to achieve access management, and on this basis to achieve patrol, patrol and attendance management. 6, can be carried out remotely via the network to the server configuration parameters. 7, the serial has 15KV ESD surge protection, network port has 2500V isolation protection. 8, all input and output ports are equipped with optocoupler isolation, with 500W lightning protection. 9, remote management, remote firmware upgrades.
