Bus couplers

The TB20 can be connected to many fieldbus systems. In this way, the I/O level can be standardised despite different PLC manufacturers and customer requirements. Depending on the fieldbus, the bus coupler can be conveniently parameterised via the free TB20 toolbox.


 Input/Output Modules

The modules for the TB20 are delivered as an "all-in-one" solution.
No headaches about which front connector or which base module is necessary. The module has the matching accessories already pre-assembled. After a click on the top-hat rail, the wiring begins.

Function Modules

Whenever something needs to be weighed, counted very quickly or SSI encoders need to be recorded, it requires suitable function modules for evaluation for the PLC. Energy meters enable energy data measurement of your plants and systems with the TB20.

System Modules

Operation with different power supply units or segmentation of the power supply can be realised with power supply/isolation modules. High-feature potential distributors monitor the supply of transmitters or 3-wire sensors and alarm the PLC in the event of a fault.

Accessories and Spare Parts

Mit vor konfektionierten Frontsteckern in verschiedenen Leitungslängen ist die Verkabelung des Systems spielend einfach. Die TB20 Toolbox unterstützt den Import der Beschriftung von anderen Planungstools. So können Sie spielend einfach die perforierten Beschriftungsbögen für Ihren Aufbau verwenden.
