The module integrates 32-bit MCU and special network chip, with simple hardware and easy to use Users can carry out secondary development, the use of network tools or self-programmed host computer software can realize the basic control The circuit board provides 8 LED indicators, indicating the opening and closing of the corresponding channel,The module automatically adapts to 10M/100M network Parameter: Input voltage:DC24V Maximum module current consumption: Less than 250mA Network speed: Less than 10M Operating temperature: -45-85 Attention. 1. The input voltage should match the operating voltage of the relay, such as selecting the relay as 5V, then the input power supply voltage should also be 5V. 2. It is not recommended to share a power supply with the input even if the output is DC.
