Schneider Electric ACX-4-0000000 Controller

The Schneider Electric Andover Continuum ACX-5740 Controller (ACX-4-0000000) is an Ethernet-based access controller in Schneider Electric’s ACX 57xx family, designed to manage building access across an Andover Continuum network with up to eight card readers. It provides 12 digital inputs and 4 digital outputs for door control and peripheral interfacing, and houses SDRAM 128 MB and FLASH 32 MB for configuration data and event logs, with an internal NiMH battery (3.6 V, 800 mAh) to preserve the real-time clock and memory during power interruptions. Power is drawn from AC up to 90 VA or from DC up to 50 W, and the unit operates from 0 to 50°C with 10–90% relative humidity (non-condensing); its enclosure measures 210 mm wide by 241 mm long by 57 mm high. The ACX-5740 designation reflects its eight-reader capacity and security-oriented capabilities within the Andover Continuum platform, making it suitable for scalable, networked access control in commercial or institutional buildings.
