RS232 RS485 Modbus Wireless Transceiver 433MHz 37dbm E90-DTU(433C37) 10km Half Duplex High Speed Continuous Modbus IOT Wireless Transceiver Module - CDBAIRUI, 0302010700000014

• Infinite packet length, support uninterrupted transmission, Modbus adaptation. Tailored for Modbus, all direct replacement of RS485 cable. All aluminum alloy shell, compact size, easy installation, good heat dissipation. Perfect shielding design, good  electromagnetic compatibility, strong anti - interference ability. Simple and efficient power supply design, support power supply device or line pressure mode, support 10~28V  power supply. 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. Transmission power up to 5w, and multi-level adjustable, all technical indicators up to the European industrial  standards. Ultra-low power consumption, the standby current is only 47mA (power saving mode and sleep mode power  consumption is lower), the emission current 1.0A. Temperature compensators are adopted to make the frequency stability better than +1.5PPM. Operation temperature range: -40°C ~ +85°C, applicable for various harsh environment, it is industrial grade. Power reverse connection protection, over-connection protection, antenna surge protection and other multiple  protection functions, greatly increasing the reliability of the station. Powerful software functions, all parameters can be set through programming: such as power, frequency, air speed, address ID, etc
