DIN mount analog input modules are designed for systems based on the Modbus RTU protocol. The modules convert analog input signals to digital data and transmit via RS485 to a controller, which may be a computer or other processor-based equipment. It provides data acquisition from a wide variety of sensors and performs all signal conditioning, scaling, linearization and conversion to either linearized ASCII data values or Modbus percent of full-scale binary values. It can measure temperature, load cells, bridges, voltage, current, frequency, as well as digital inputs and digital outputs.
