I/O modules
Efficient and secure signal transport

Efficient automation starts with reliable signal processing. The I/O modules from Balluff enable seamless connection of sensors and actuators to control systems and thus ensure optimized machine and system performance.
I/O modules from Balluff connect binary and analog sensors and actuators to the control level via a bus. The use of the modules significantly reduces the number of cables.
I/O modules also offer additional functions for signal pre-processing and extended diagnostic options. Different designs and connection technologies enable solutions for a wide range of applications, even under extreme environmental conditions.
