The Zelio Logic SR2/SR3 series by Schneider Electric provides an alternative to solutions based on cable logic or specific cards. This range is compact, with Modbus or Ethernet communication extension modules compatible with the device. Signal the device remotely, or on-site, you can control the module on your terms.

• Easily programmable interface, safe programming allows you to run coherence testing, simulations and monitoring modes to ensure complete control over your devices.

• A real-time clock built in

• 6 to 10 outputs & 4 to 10 inputs (depending on model) allowing you versatility in the number of stand-alone devices you need to input/output to.

• Low power consumption with a generous supply voltage ranging from 12 V dc up to 24 V dc (see specifications for model specific voltage).

• DIN Rail or panel mounting with screw terminals depending on your need.

• Cost-effective in reducing space needed with the compact models vs. other basic modules.

• Intuitive programming with Zelio Soft 2 software using function block diagram (FBD): this has 32 pre-programmed functions, 7 Grafcet functions, 6 logic functions.

OR

contact language (LADDER): 12 pre-programmed functions.

• LCD backlight display for easier accessibility in darker areas.

• 10 years back-up (EEPROM memory)

Logic modules are useful for when you need to perform a process without human intervention, therefore the list is not limited. Logic Modules may even be connected to other Logic Modules for example. Below you’ll find some typical applications:

• Control systems for smaller machinery/replacement of controls

• Lighting management

• Heating and air conditioning controls

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.
