Main Function Description

The REXROTH VT-VSPA2-1-20/V0/T1 is engineered as a centralized, intelligent pneumatic control node. Its core function is to house and control up to 20 individual pneumatic valve cartridges, each acting as a switch for a compressed air line to a specific actuator. The integrated electronic controller, defined by the /T1 option, manages all valves. It communicates with the machine’s master PLC over a high-speed industrial network (specified by the option code), receiving commands to energize or de-energize specific solenoids.

This design eliminates the need for individual valve wiring back to the main cabinet, as all valves are connected via a single fieldbus cable and a single air supply manifold. The terminal provides real-time feedback on valve status and diagnostic information (like coil faults) back to the PLC. Setup and parameterization are performed using Rexroth’s IndraWorks engineering software, allowing for easy configuration of valve functions and diagnostic parameters. The robust construction ensures leak-free operation and resilience in industrial environments with dust and moisture.
