DT400 is an advanced controller designed for speed regulation of electronic fans installed on finned heat exchangers. DT400 has been specifically developed for mission critical applications such as datacenters and power generation.
Based on a modern platform equipped with a latest-generation processor, it allows local FW updates through the integrated USB port or remotely via GR IIoT gateways.
Features two isolated MODBUS RTU RS485 interfaces, two serial interfaces for expansions, one micro USB port and an optional LAN port with integrated MODBUS TCP/IP or SNMP protocol. A wide range of communication protocol converters is also available (BACnet, Konnex, Ethernet, Ethernet IP, Profibus, Profinet and many others).
The integrated Bluetooth connection and the free HyCo application allow monitoring and configuration of the DT400 controller from Android mobile devices.
Thanks to carefully designed control algorithms, DT400 enables efficient fan group management by reducing energy consumption and increasing efficiency.
Thanks to expansion modules, it can increase its I/O equipment. Specialized expansion modules are also available for managing modern adiabatic systems.
Equipped with a user interface consisting of 6 keys and a color graphic display with 320x240 pixel LED backlight. Thanks to a dedicated serial line, it is possible to add a second remote user interface.
Easily adapts to a wide variety of operating conditions, allowing configuration and programming of analog and digital I/Os.
Natively integrates a Plug & Play connection to GR IIoT gateways to transmit process data to the HyCloud platform, enabling monitoring and support of the heat exchanger anywhere in the world.
