E90-DTU is a wireless data transceiver with the function of digital data processing, digital modulation and demodulation, FEC, balanced soft decision, etc.. Wireless data transceiver provides transparent RS232 / RS485 interface, different with the analog FM transceiver plus MODEM analog digital transceiver.
Wireless data transceiver working as a communication medium,as well as the fiber, microwave, the same line, has a certain scope of application: it provides some special conditions in the private network monitoring signal real-time, reliable data transmission,with the features of low cost, convenient installation and maintenance,diffraction ability, flexible network structure, range of coverage,suitable for the occassion of dot and scatter, complex geographical environment, connecting with PLC,RTU, rain gauge, level gauge and other data terminals.
All
the core components are imported originally, compared with the current
im-ports of digital transceiver, we are the most advanced, most cost
effective and the smallest one.
Transmission power is optional: 0.5 - 5W, all technical indicators have met the European industry standards.
Use temperature compensation circuit, the frequency stability is better than $1.5PPM.
With operating temperature range: -40 °C - +70 C, adapting to a variety of harshworking environment.
All
with aluminum alloy shell, compact, easy installation, good heat
dissipation;perfect shielding design, good electromagnetic compatibility
and strong anti-in-terference ability.
Power reverse protection,
over-protection, antenna surge protection and other multiple protection
functions, greatly increase the reliability of the transceiver.
Powerful software features, all parameters can be programmed to set: such as power, frequency, air data rate, address ID, etc.
Ultra-low
power consumption, standby current is 50mA (the power consumption of
power saving mode and sleep mode is lower), the transmitting current ≤
1.2A(5W).
With watchdog and accurate time layout, in the event of
an exception, the module will automatically restart and continue to
follow the previous parameters to oper-ate.
