The logic relay is an electronic control relay with logic
functions, timer, counter and time switch functions. It is also
a control and input device rolled into one. With the logic
relay you can create solutions for domestic applications as
well as for tasks in machine and plant construction.
Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the CL display.
