Description
Schneider Electric SR3B261B Zelio Logic Modular Smart Relay is a range of smart relays for simple automation systems with 10 to 40 I/O. The compact smart relay offers a real alternative to solutions based on hardwired logic or specific cards. It comes with a screen and a clock. Checks program memory at each power-up and from 0 to 240 with ladder programming number or control scheme lines.
Zelio Logic is easy to use and represents a real alternative to solutions based on hardwired logic or special cards. It offers 10 normally open contact relay outputs and 16 discrete inputs. It is a smart relay with a nominal supply voltage of 24V, a maximum supply current of 280mA (without extension), and a power consumption of 7.5VA without extension. It is a product with protection classes IP20 and IP40. It weighs 0.4 kg.
Schneider Electric SR3B261B Zelio Logic Modular Smart Relay complies with EN/IEC 61000-4-5, EN/IEC 61000-4-11, EN/IEC 61000-4-2 Level 3, EN/IEC 61000-4-6 Level 3, EN/IEC 60068-2 - 6 Fc, EN/IEC 60068-2-27 Ea, EN/IEC 61000-4-4 Level 3, EN/IEC 61000-4-3 and EN/IEC 61000-4-12. Easy to select, install, and program, Zelio Logic is suitable for all applications. It offers the flexibility to choose between 2 series, compact or modular, expandable, and 2 programming languages (FBD or LADDER). Zelio Logic is easy to use and offers a real alternative to solutions based on hardwired logic or specific cards.
