  • The main function of this product is to centralized measurement convert multi-channel standard DC transmission signal into digital signal output, can measure 8 channels of current and 4 channels of voltage input signals. Multi - channel DC intelligent transmitter can be widely used in a variety of industrial control and measurement systems, and mainly measure the 4 ~ 20mA or 0 ~ 10V output signal of a variety of pressure, temperature, flow and power transducer. Output communication interface is RS485 or RS232, wide range of power supply DC 9 ~ 30V, using the standard MODBUS-RTU communication protocol.
