Zelio Logic smart relays
Compact and modular smart relays
“Zelio Soft” programming software
FBD language allows graphical programming based on the use of predefined
function blocks.
This language provides the use of 23 pre-programmed functions for counting, time
delay, timing, definition of switching threshold (temperature regulation for example),
generation of impulses, time programming, multiplexing, display, etc.
Timer. Function BH.
