Overview
EZD is an electronic HMI unit and control relay with the
following features:
• Logic functions,
• Timing relay and counter functions,
• Time switch functions,
• Arithmetic functions,
• PID controllers,
• Operator and display functions.
EZD is a display, HMI, control and input device in one. With
EZD you can create solutions for domestic applications as
well as for tasks in machine and plant construction. EZD is a
modular and flexible device.
The integral EZ-NET network enables the connection of up to
eight EZ-NET stations to form a single control system. Each
EZ-NET station can contain a program. This allows the design
of systems using high-speed controllers with decentralized
intelligence.
In Terminal mode, the EZD can be used to control any device
in the network and display data from it, regardless of whether
it is an EZ800 or an EZD. In this mode, the EZD makes its
keypad and display available to the other device for use.
Two devices, EZD with EZ800 or EZD, can be connected
simply via the serial interfaces.
Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the EZD display. For
example, you can:
• connect make and break contacts in series and in parallel
• switch output relays and auxiliary contacts,
• define outputs as coils, impulse relays, rising or falling
edge-triggered relays or as latching relays,
• select timing relays with different functions:
– on-delayed,
– on-delayed with random switching,
– off-delayed,
