3503EC1 series intelligent modules have a small external volume, and the products adopt the rail snap-in mounting method, which is convenient for intensive installation. Multi-protection, isolation design, strong anti-interference ability, high reliability. Series modules can be set up to four input channels, each channel can be programmed for thermocouple, RTD, current, voltage, resistance and other different specifications, with various types of sensors, transmitters.

The communication interface of 3503EC1 adopts Modbus-RTU mode, which is highly versatile; it can be connected to an external display board through the interface of the instrument panel, which is convenient for debugging. Small external volume, the product adopts the rail snap-in mounting mode, which is convenient for intensive installation. Multiple protection, isolation design, strong anti-interference ability and reliability.

3503EC1 series intelligent module can be one way signal input and two way signal output. Small external volume, the product adopts the rail snap-in mounting method, which is convenient for intensive installation. Multi-protection, isolation design, anti-interference ability, high reliability. 3503EC1 input signals include various types of mV, RTD, thermocouple signals, can provide transmitter power supply to the field of two-wire transmitter to return to the current signal, convenient for on-site debugging. The first output signal is PID control signal output, which can be selected as standard current output or relay output; the second signal is variable transmission or RS485 communication output. The communication interface of the instrument adopts Modbus-RTU mode, which is versatile and convenient to use.
