In the logic module market, the PLC logic relay system is the first to combine logic, interface, and field connection levels in a single solution. This means that you can switch and control I/O signals using a single compact system. You can combine the new PLC logic module with the corresponding plug-in relays as required. The modular structure opens up a wealth of applications.

Your advantages

• High availability, thanks to plug-in switching elements

• Flexible combinations: install different relay types in the system according to switching requirements

• Tailor-made configuration: define each relay channel individually as an input or output

• Convenient and tool-free wiring with push-in connection

• Easy implementation of projects, thanks to intuitive software

The system at a glance

You can flexibly extend the system, thanks to the wide choice of different modules. In addition to the basic module, extension modules are also available for more complex tasks. Eight freely-selectable PLC-INTERFACE terminal blocks are available for each logic module. Acquire and switch up to 48 I/O signals with one basic module and two extension modules.

Components of the relay logic system

1) Basic module

PLC logic processes 16 I/O signals with just one basic module, with a design width of just 50 mm.

2) Extension modules

The basic module and the extension module are connected via integrated connectors - no tools required.

3) Memory module

Save programs or easily copy them to other devices.

4) Relay modules

Channel-specific configuration is possible thanks to the modular design with the widest variety of relay terminal blocks.

LOGIC+ software

Configuration is quick and easy with the intuitive LOGIC+ programming software. Ladder (LD) and function block diagrams (FBD) can be created by selecting the relevant functions and their connection using drag & drop. In doing so, the following function blocks are available to the user:

 Basic functions: AND, OR, NOT, XOR

 Mathematical functions: add, divide, multiply, subtract, generate absolute value

 Positive and negative edge detection

 RS and SR flip-flops

 Switch-on and switch-off delay, pulse encoder, pulse stretching, weekly clock timer

 Up and down counter

 Analog and digital comparators

 Special functions, e.g., solar altitude calculations are available for download

The clear separation in the program editor, toolbox, hardware view, and signaling window are particularly user friendly. What’s more, the entire program can be simulated and tested both online and offline. Numerous examples of use make it easy to get familiarized with the software.
