Interfacing and System Integration - 4-20mA Current Loop

This range of noise processors and noise warning signs have a standard 4-20mA current loop output that maps to the measured sound level. 4-20mA current loop is a common method used by industrial process control systems (SCADA, PLC, etc) to monitor analog signals. The main advantage of current loop over a DC output is that the signal is not affected by voltage drops due to resistance in the cabling. With the devices listed here, the minimum signal (4mA) and maximum signal (20mA) can be mapped to sound levels, ensuring the measurements cover the range that you are interested in.
