Zelio Logic is a solution for managing simple automation systems with flexibility and simplicity. It includes basic and expansion types to meet different scales and requirements. The basic type is suitable for systems with 10 to 20 input/output points, while the expansion type supports up to 40 input/output points with higher performance and flexibility. Programming and parameter setting can be done using Zelio Soft software, enabling fast and efficient operation. Zelio Logic is widely used in industrial and building applications, including mechanical automation systems, lighting management, access control, heating and air conditioning system management, etc.
The Zelio Logic controller family from Schneider Electric provides compact, easy‑to‑use automation solutions. The basic SR2 models offer 10, 12 or 20 input/output points, while the SR3 expanded models start with 10 or 26 points and can be extended to 40 I/O points using optional modules.
The controllers can be programmed with the Zelio Soft PC software using ladder (LADDER) or function‑block (FBD) languages, or directly on the device via its front‑panel keys. Optional communication modules add Modbus and other interfaces, and a range of expansion modules increase I/O capacity. This manual is written in Chinese.
