Programmable multi-channel stand-alone data acquisition systems

Programmable multi-channel systems include sophisticated devices that offer up to 30 or more input channels including both analog and digital measurements, programming capability that allows measurements at a wide range of time intervals, on-board data processing, and outputs that can control external devices. These systems are often used for whole-building monitoring, especially projects focused on mechanical system performance and electric loads when most sensors can be placed in a mechanical room and cabled to the data acquisition system. These systems will often support communication from remote sites via telephone modem, cell phone, or internet.
