Overview
The TU 709F/710F terminal block functions as a base for the CI 741F PROFIBUS communication interface. Designed for handling 24 V I/O signals, it ensures reliable power distribution and grounding in industrial automation systems. The terminal block features a spring-type design for secure connections, making it highly durable and resistant to vibration. It is ideal for use in control panels and machinery where robust electrical connections are required.
