Process Variable Transmitters includes DIN rail mount, works with any voltage output sensor and 4-20 mA & 0-20 mA output sensors, fault detection, buffered transducer output and filter option. They are compatible with several types of inputs and provide a 4-20 mA output proportional to the overall measurement. Each unit processes the signal to determine overall amplitude and outputs a 4-20 mA dc current that is proportional to 100%.
