Product Description
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 a display and a clock, and checks program memory on each power-up. Zelio Logic controller makes automation easy. It offers 4 relay outputs with normally opened contact and 8 discrete inputs. Rated at 12V DC, draws up to 120mA and 1.5W without extension, with IP20/IP40 protection. It weighs 0.25kg. Complies with EN/IEC standards for EMC and environmental resilience, including surge, electrostatic discharge, vibration, and power immunity tests. It is delivered in 1 package (PCE type). It is mounted on a 35mm DIN rail. Simple to select, install and program, Zelio Logic is suitable for all your applications. Easy to use, Zelio Logic offers a genuine alternative to solutions based on cabled logic or specialized cards.
Key Features
- Simple ladder programming adapted for non-specialists
- EEPROM backs up data for 10 years, recoverable after power loss
- Integrated LCD display for clear monitoring and navigation
- Simplifies automation without complex cabling
