This Schneider Electric Zelio Logic SR3 Discrete I/O Extension Module Smart Relays uses a supply voltage of 24 volts alternating current, has 6 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 60068-2-27 Ea, EN/IEC 61000-4-5, EN/IEC 61000-4-12 and EN/IEC 61000-4-4 L3 standards. Easy to use, Zelio Logic provides a real alternative solutions based on cabled logic or specific cards.
