EZ700 basic unit
EZ is an electronic control relay with logic functions, timer,
counter and time switch functions. It is also a control and input
device in one that can perform many different tasks in
domestic applications as well as in machine building and plant
construction.
Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the EZ display. For
example, you can:
• Connect make and break contacts in series and in parallel
• Connect output relays and markers,
• Use outputs as relays, impulse relays or latching relays
• Use multi-function timing relays with different functions
• Use up and down counters,
• Count high-speed counter pulses
• Measure frequencies
• Process analog inputs, EZ-AB, EZ-DA, EZ-DC, (EZ512..:
two analog inputs, EZ700: four analog inputs)
• Display any texts with variables, enter setpoints
• Use year time switches, 7-day time switches, EZ…-..-.C(X),
• Count operating hours (four retentive operating hours
counters integrated)
• Track the flow of current in the circuit diagram
• Load, save and password-protect circuit diagrams
