S3101 is a high quality and low cost analog data acquisition module. S3101 has total 12 channels input, each input has lightning and surge protection.  Output use RS485 BUS with surge protection, to reduce interference by serial port communication, the output isolated by high speed opto-couplers. The modules are slave devices that can be easily controlled via the RS485 serial interface using the industry standard Modbus protocol.
