Product Description ADS-DM801/821 Universal Input Signal Isolator is a universal input signal isolator that can support multiple input signals, including thermocouples, thermal resistors, DC current/voltage inputs, and more. These input signals can be selected through parameter settings. The input, output, feeder, and power supply of the isolator are isolated from each other, ensuring the safety and stability of the signal. In the standard configuration, the ADS-DM801/821 Universal Input Signal Isolator provides feeder functionality. Specifically, the standard configuration of the 801 model has one output port, while the standard configuration of the 821 model has two output ports, which are also isolated from each other. The power range of this isolator is 10VDC to 30VDC, and the power consumption is less than 4.8W. This means that it can operate at low power consumption and is suitable for various power supply environments. In summary, ADS-DM801/821 Universal Input Signal Isolator is a powerful and flexible universal input signal isolator that can meet the needs of different application scenarios.
