Feature

●E90-DTU (433C33) is a data transmission station that adopts extremely advanced ultra-narrow band modulation technology. On the original basis, power amplifier (PA) and low noise amplifier (LNA) are built in, so that the maximum transmitting power reaches 0.5w and the receiving sensitivity is also improved to a certain extent. Compared with the products without power amplifier and low noise amplifier, the overall communication stability is greatly improved.
●Different from the traditional data transmission station, E90-DTU (433C33) is specially developed for Modbus application scenarios. The feature of unlimited packet length can replace the communication cable, making it the most convenient choice for Modbus wireless upgrade. The station works in 433MHz frequency band, with communication distance up to 4km
●Wireless digital radio as a medium of communication, as well as optical fiber, microwave, open wire, there is a certain scope of application: it provides some special conditions, private network monitoring signals in real-time and reliable data transmission, low cost, easy installation and maintenance, diffraction capability is strong, flexible network structure, the coverage is far characteristic.
●Ultra-low power consumption, the standby current is only 31mA (power saving mode and sleep mode power consumption is lower), the emission current 0.9A. Built-in watchdog, and accurate time layout, once an exception, the module will automatically restart, and can continue to work in accordance with the previous parameter Settings
●Warranty: We have 1 year warranty. If you need user manual or any problems contact with us free.
