I/O System
Products Overview
A Distributed Fieldbus I/O System is a networked setup in industrial automation that distributes input and output (I/O) modules across a facility. Unlike traditional centralized systems, this architecture uses fieldbus communication to connect remote I/O modules to a central control system. It offers scalability, flexibility, and reduced wiring, leading to cost savings and simplified installation. This system enhances reliability by minimizing single points of failure and can be tailored to diverse industrial environments and applications.
Bus couplers
TB20 bus coupler
PROFINET PROFIBUS-DP EtherNet/IP EtherCAT DeviceNet Slave Modbus/TCP CANopen |
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module. Note: Individual modules cannot be combined with the IO systems of other manufacturers.

Function Modules
Counter, 32 Bit
5 V (RS422), 4 MHz 24 V, 500 kHz |
Counters are used to detect pulses that are faster than a controller’s cycles, i.e., signals that the controller will be unable to detect properly and that therefore need to be pre-processed.
