Run your simple automation systems successfully with this logic module from Schneider Electric. It's a smart relay that provides a viable alternative to cable logic or specific card control systems. The module supports FBD (function block diagram) and Ladder logic coding, which can be simply followed via free software. It’s compact and easily fitted to any DIN rail or conveniently screwed to a panel. This versatile device is suitable for automation control across a range of industrial and commercial applications.

• Can be programmed via operating panel interface or a connected PC
• Operates safely within a wide temperature range from -20°C to +55°C
• Compatible with common programming languages – Ladder logic, FBD, SFC

• Control of small production and assembly equipment
• Automation of HVAC (heating, ventilation and air conditioning) and lighting systems
• Monitoring of shutters, rollers and access control

Function Block Diagram (FBD) is a coding language for programmable logic controller designthat's able to read function between input and output variables. A function is described as a set of elementary blocks. Input and output variables are connected to blocks via connection lines.

Schneider Electric now offers a new generation of expandable intelligent relays, offering substantial advantages in flexibility and functionality. Zelio Logic 2 Smart Relay is the optimum solution to control tasks such as automating small machines within industry, lighting, HVAC and access control within buildings.

With the small footprint, simple programming, powerful control functions and the possibility of changing or modifying the program in case of changed application requirements, it offers great savings in space and price compared to other options.

Choose between two new series - Compact and Modular. The Compact series is not expandable and is available with the following I/O block sizes: 10 I/O, 12 I/O and 20 I/O.
The Modular series is available with 10 and 26 I/O basic units and is expandable up to 40 I/O with the latter. Apart from this flexibility both new series are programmable using FBD, ladder and Grafcet SFC programming languages.
User friendly design for easy programming and operation, either directly from the module using the navigation buttons or via Windows based software.
