This Schneider Electric Zelio Logic SR3 compact smart relay / programmable controller uses a supply voltage of 24 volts direct current, has 10 inputs / outputs with screw-clamp terminals. It has an integrated clock and LCD display. This compact smart relays / programmable controller is ideal for management, remote control or monitoring of simple automation systems. It is suitable for both industrial and commercial applications. It has compact form-factor, allowing installation on DIN rail. It also offers simple programming, display and diagnosing of malfunctions display and navigation buttons. 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. Simple to select, install and program, Zelio Logic is suitable for all your applications. Flexible, it offers you the choice of 2 ranges, compact or modular, extendable and 2 programming languages (FBD or LADDER). Easy to use, Zelio Logic provides a real alternative to solutions based on cabled logic or specific cards.
