"This Schneider Electric Zelio Logic SR2B compact smart relay / programmable controller uses a supply voltage of 12 volts direct current, has 12 inputs / outputs with screw-clamp terminals, has an integrated clock and LCD display. This compact programmable relay 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. This product meets EN/IEC 61000-4-11, EN/IEC 60068-2-6 Fc, EN/IEC 61000-4-12, EN/IEC 61000-4-2 level 3, EN/IEC 61000-4-5, EN/IEC 61000-4-3, EN/IEC 61000-4-4 level 3, EN/IEC 60068-2-27 Ea and EN/IEC 61000-4-6 level 3 standards. 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."
