Data sheet MCX15B Programmable controller MCX15B is fitted with or without graphic LCD display. It is an electronic controller that stands on the top of the MCX range, thanks to the large number of its inputs and outputs. It holds all the typical functionalities of MCX controllers: • programmability • connection to the CANbus local network • up to two Modbus RS485 opto-insulated serial • interface Furthermore it is available in two models, powered at 110 / 230 V AC or 24 V AC • 10 analog and 18 digital inputs • 6 analog and 15 digital outputs • Power supply 24 V AC / 20/60 V DC and 110 V / 230 V AC • Remote access to data through CANbus connection for additional display (LCD available) and keyboard • RTC clock for managing weekly time programs and data logging information • Up to two Modbus RS485 opto-insulated serial interface • Available with graphic LCD display for showing the desired information and without display • Dimensions 16 DIN modules
