Description
Zelio Logic, Modular smart relay, 26 I/O, 24v DC, clock, display
This Zelio Logic SR3 compact smart relay / programmable controller uses a supply voltage of 24V direct current. It has 26 inputs / outputs with screw-clamp terminals. It has compact design, allowing installation on DIN rail. It also offers simple programming, display and diagnosing of malfunctions display and navigation buttons. Its simple ladder programming makes it adapted for non-specialists.
Features:
• 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
• More I/O than SR2 model, for larger applications
