Introduces the features and application scenarios of Zelio Logic smart relays
Zelio Logic smart relays are compact, modular devices designed for small automated systems in industrial and commercial applications, such as packaging machines, textile equipment, agricultural machinery, barriers, lighting, and HVAC control. They support up to 20 I/O in compact form and can be expanded to 40 I/O with optional I/O extensions and Modbus communication modules.
The manual describes programming via the relay's buttons in ladder language or through the PC‑based Zelio Soft software (ladder or function‑block diagram). It also covers hardware specifications, power supply options, input/output characteristics, environmental ratings, and certification details, providing all information needed for installation, configuration, and maintenance.
