ALIEM module

8 (16 single-ended) analog inputs and 4 digital inputs converter 
 

ALIEM module is an analogue/digital interface between a wide range of sensors and devices and the master unit through RS232/485 Modbus-RTU protocol. Typically one or more ALIEM modules are used to increase the number of inputs in the Alpha-Log data logger, but it can be used as indipendent device to inter-face sensors to third-part devices with RS232/485 Modbus input requirement. ALIEM has been explicitly designed for environmental/meteorological applications. Robust, well protected from electrical disturbes and reliable, ALIEM makes measurements possible even in the most severe environments, while the 18-bit A/D converter ensures accurate and reliable data in classic meteorological, hydrological and air quality applications and, more generally, in any environmental application.
