The Zelio Logic 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. For use with Zelio Logic Modules.

• A real-time clock built in with a 10 year back up time @ 25°C.

• 6 Outputs & 8 Inputs (No display).

• Low power consumption with a generous supply voltage of 24 V dc. The base unit should be chosen such that the supply voltage matches the base unit it will be used with.

• 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.

• IP20 & IP40 protected (protection of water sprays and solid objects up to 1 mm e.g. tools, wires).

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

This Schneider Electric Zelio Logic SR3 Discrete I/O Extension Module Smart Relays uses a supply voltage of 24 volts alternating current, has 10 inputs / outputs contact with screw-clamp terminals. This Discrete I/O Extension Module Smart Relays provides Zelio Logic relays with additional inputs and outputs. It has a compact form-factor, allowing installation on DIN rail. Simple ladder programming, adapted for non-specialists. Discovery package, coming with Zelio Soft programming software, the simplest way to learn and use this relay. Built-in EEPROM flash memory for data backup up to 10 years, easy-to-recover after a power shortage or incident. More I/O than SR2 model, for larger applications. The main application of this module is industry and building/service sector. This product is certified by C-Tick, GL, UL, CSA and GOST. It meets EN/IEC 61000-4-2 L3, EN/IEC 61000-4-5, EN/IEC 61000-4-6 L3 and EN/IEC 60068-2-6 Fc standards. Easy to use, Zelio Logic provides a real alternative solutions based on cabled logic or specific cards.

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.
