Effectively manage your light-duty industrial equipment with this logic module from Schneider Electric. It translates input signals from sensors and actuators to output functions on your machinery, making operation easy without the need for human intervention. This control unit’s thermoplastic housing is durable and resistant to impact, so you can use it in harsh conditions. It also serves as an insulator to protect you from electric shocks. The energy-efficient unit consumes just 100mA (milliamperes) of supply current and is lightweight at 220g, making it easy to handle.

• Quick and simple DIN rail mounting saves time and effort
• Can read both analogue and digital input signals for versatility
• 4kV rated impulse withstand voltage to withstand sudden power surges for electrical safety
• Programme memory checks at startup to ensure reliable performance
• Mechanical durability of 10,000,000 cycles for a long service life

• Construction industry
• Food production plants
• Small machine control panels

Yes, it is. The front panel of this logic module has an IP40 (ingress protection) rating that indicates resistance to dust and objects larger than 1mm in size.

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.
