Schneider TSX3722AC | Robust PLC | Modicon Premium Controller

The Schneider TSX3722AC delivers reliable control for demanding industrial automation environments. This robust PLC features a built-in power supply for simplified system integration. It supports 256 discrete I/O and 32 analog I/O channels for medium-scale applications. Weighing only 1.2 kg, the Schneider TSX3722AC mounts directly into a Premium rack. Its dimensions measure 187.9 mm x 151.5 mm x 160 mm.

Processing Power and Memory Architecture

The Schneider TSX3722AC executes 70 instructions per millisecond for efficient real-time control. This controller includes 128 KB of flash memory for program and data storage. It also features 32 KB of internal RAM for fast variable access. Moreover, the Schneider TSX3722AC supports up to 4 communication modules for network expansion. Consequently, you can build distributed control systems with multiple remote I/O drops.

Built-in Communication and Energy Storage

The Schneider TSX3722AC features a built-in multi-standard serial port for programming. This port supports Modbus, Uni-Telway, and character mode protocols for flexible connectivity. The controller also includes a Mini DIN connector for terminal or HMI connections. Importantly, the Schneider TSX3722AC contains a lithium battery for SRAM data backup. This battery provides energy storage for up to 1,000 hours without external power. Therefore, your program remains safe during extended power outages.

Installation and Application Details

The Schneider TSX3722AC mounts directly into the leftmost slot of any Premium rack. This controller includes its own power supply, so it needs no external power module. You need PL7 Pro software version 4.3 or higher for programming. The Schneider TSX3722AC suits harsh environments like metalworking, mining, and outdoor installations. Its robust design withstands high vibration and shock levels. Thus, this controller delivers dependable performance where standard PLCs often fail. Replace the lithium battery every 5 years under normal operating conditions.
