Zelio Logic Smart Relays – Compact. Zelio Logic Smart Relays are designed for use in small automated systems and are utilized in industrial and commercial applications. The relays come with 10 or 26 I/O depending on the model and can have up to 40 extended I/O. Programming and Software: Simple programming can be done independently using the buttons on the front of the relay or on a PC using Zelio Soft software. Programming with a PC can be done either using LADDER language or in Function Block Diagram (FBD) language. Memory: The Zelio Logic Smart Relays feature memory buffering that allows programs to be copied to other Smart Relays. The memory enables the storage of a backup copy of the program before the product is replaced, and for relays without a display or buttons, the copy program is automatically transferred upon power-up. LCD display with backlighting, DIN rail or panel mounting, includes real-time clock, 4 analog output channels, 10 ms cycle time, 10 years buffering (EEPROM memory), screw terminal connections, protection class IP20.
