E64-DTU (433NW20) - Wireless Data Transmitter

E64-DTU (433NW20) - Wireless Data Transmitter

E64-DTU (433NW20) is suitable for low-power, main-multiple slave star networks. Its biggest feature is that it
supports up to 31 slave data to be sent to the host at the same time, and supports WOR working mode of slave, withaminimum receiving power consumption of about 3mA. Data reliability and correctness are guaranteed by strict datachecking and automatic retransmission mechanism between master and slave.

The E64-DTU ((433NW20) module supports both host and slave modes. In the host mode, the module listensandreceives data from multiple slave machines. In slave mode, the user can set the module to work in WORmode or sendmode. WOR mode allows the host to initiate data wake-up to the slave, while sending mode only allows the slavetoinitiate data to the host.

The maximum transmission power of E64- (433NW20) module is 100mW, using command transmissionmode, operating at 425~ 451.3mhz. The module USES UART serial port to communicate with user MCU, and its workingvoltage 

Features:

• All core components are originally imported; our transceiver modems have much advanced functions with smaller sizeand lower cost.
• The top TX power is 100mW, all technical parameters meet European industrial standards.
• Temperature compensators are adopted to make the frequency stability better than ±1.5PPM.
• Operation temperature range: -40℃ ～+85℃, applicable for various harsh environment, it is real industrial gradeproducts.
• Aluminum alloy case, compact size, great heat dispersion; good shielding, prime electromagnetic compatibilityandstrong anti-interference.
• Power reverse & overload protection and antenna surge protection functions significantly improve the reliability.
• Parameters can be configured by programming, such as TX power, frequency point, air data rate, address andsoon.
• Ultra-low power consumption, standby current is only 14mA (even lower under power-saving and sleep modes), TXcurrent ≤0.13A.
• Embedded watch-dog and precise time layout, modem will restart automatically upon abnormal situation andworkwith previous parameters.
• The transceivers adopt original SEMTECH SX1278 chip, customers highly comment the products becauseof thesuper reliability.
