Industrial Grade Rail-Type 16 Channel DI/DO/AI/AO LoRa Transmission Equipment

A LoRa transparent transmission device with an IP40 protection level. It is a wireless relay device specially used to transmit up to 16 DI/DO AI/AO signals through LoRa. This wireless gateway uses an industrial-grade high-performance 32-bit communication processor and uses an embedded OS real-time operating system as the software support platform. It can be installed in 35mm rail-mounted and wall-mounted installations to meet the needs of different application sites.

● ISM 430M-490M free frequency band, no need to apply for frequency usage fees, the default is 490M, avoiding the 433M congested frequency band;

● 16 channels of DI/DO/AI/AO, supports up to 16 channels, every 2 channels are a unit, DI/DO/AI/AO can be configured arbitrarily, such as 4 channels DI+4 channels DO+4 channels AI+4 channels AO, or 8-channel DI+8-channel AI, each channel has indicator light status indication;

● Analog input supports 12-bit resolution output, 2‰ accuracy, supports 2-wire, 3-wire, and 4-wire sensor access; supports 0-20mA, 4-20mA, 0-5V, 0-10V, -5V-+5V 5 An analog input signal.

● Provide supporting PC-side test software to facilitate debugging, parameter configuration, and modification;

● Device A detects AI/DI data and transmits it to device B through LoRa transmission. The AO/DO status of device B is consistent;

● Dual DC power supply (5.08 terminal block): It can be powered by DC9-70V or AC7-55V wide range power supply. The power supply has automatic polarity detection function. There is no need to distinguish between positive and negative poles during installation; supports internal isolation, redundant dual power input; anti-reverse protection

● The power supply supports overload protection; complies with industrial level four electromagnetic compatibility requirements; super lightning protection function: anti-lightning strike, resistant to induced high voltage, anti-surge, etc.;
