The XPS Excitation Power-Saver Switch is a special feature on selected Spectrum 4000 Current Loop data loggers that minimizes power consumption and extends the life of external battery-powered 4-20mA transducer circuits.
The XPS was developed for remote two-wire 4-20mA transducer monitoring applications where no line power source is available. The switch allows users to connect one or more transducers to their data logger, power them with an external battery, and have the circuit last for an extended period of time without premature draining of the battery.
An internal software-controlled switch, the XPS features a user-adjustable transducer warm-up time to ensure stable and accurate transducer operation.
