The Schneider TSX3721AC serves as the base unit inside Modicon TSX Nano and Micro automation platforms. Engineers select this unit when compact control tasks demand an integrated power and processing platform. Consequently, the base delivers reliable logic execution across continuous plant operations.
Physical Dimensions and Weight Data
Cabinet space often limits how technicians arrange controller hardware inside compact enclosures. Therefore, this base keeps a slim profile while supporting full integrated functionality. It weighs roughly 0.6 kg and measures 110 mm in height. Additionally, its width spans 75 mm with a depth of 90 mm.
Interfaces and Connectivity Features
Reliable control depends on secure terminations at every input and output point. The unit provides screw terminals that accept wires up to 2.5 mm². Furthermore, front-panel LEDs let technicians verify channel and fault status instantly. The base mounts directly onto DIN rail without additional brackets.
Component Count and Energy Storage
Internal architecture shapes both diagnostic coverage and service life. This base carries more than 200 discrete components across its integrated stages. Moreover, a lithium battery retains configuration data for up to 90 days. This storage protects non-volatile memory whenever plant power drops.
