Zelio Logic 2 is a programmable relay that can be used for applications that need greater flexibility than a simple relay, but are too small or simple for the smallest PLC. Designed to accept and control outputs just like a relay, the logic is set up or altered via simple keystrokes on the front of the unit or by utilizing the user-friendly ZelioSoft software. Zelio Logic’s small size and ease of programming provides a competitive alternative to traditional relays, timers, and counters. Read more...

TWIDO is an ultra-compact controller especially designed for small control systems, providing the ideal solution for both simple stand-alone applications and compact machines. With small footprint bases and slim expansion modules, Twido packs more functionality into a smaller footprint and panel size can be significantly reduced. By adding expansions, Twido can accommodate more than 200 discrete and analog I/O. Read more...
