Wi-IO 100 series is an advanced and versatile four-in-one IO card designed for applications in Building Management System and Industrial Automation projects. The unit can monitor digital input and analog input (0-10V/4-20mA). It is also capable of controlling digital output (dry contact) and analog output (0-10V/4-20mA). It has a standard serial communication (Modbus protocol over RS485) for interfacing with PLC/HMI, Gateway, and SCADA software.
