Information
This product is part of the Zelio Logic range, an offer of smart relays for simple automation systems from 10 to 40 I/Os. The compact smart relay provides a real alternative to solutions based on cabled logic or specific cards. It comes with display and clock. Checks program memory on each power up and 0 to 240 with ladder programming number or control scheme lines. Easy to use, Zelio Logic provides a real alternative to solutions based on cabled logic or specific cards It offers 10 relay outputs with normally opened contact and 16 discrete inputs. It is a smart relay with a rated supply voltage of 24V, a maximum supply current of 280mA (without extension) and a power consumption of 7.5VA without extension. It is an IP20 and IP40 rated product. It weighs 0.4kg. This product meets 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 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.
