OPT-B4-V 256P Vacon Inverter IO Signal Card I/O Expansion Board
The Vacon OPT-B4-V 256P is a dedicated PROFIBUS DP communication option module designed for seamless integration of Vacon 100 and Vacon 20 AC drives into PROFIBUS-based industrial automation networks. Developed by Vacon (now part of Danfoss Drives), this compact plug-in module enables real-time control, parameter access, and diagnostic data exchange between the drive and higher-level PLC or DCS systems—enhancing process efficiency, reducing wiring complexity, and supporting Industry 4.0 connectivity in applications such as pumps, fans, conveyors, mixers, and extruders.
Engineered for reliability and easy installation, the OPT-B4-V 256P supports standard PROFIBUS DP protocols with 9-pin D-sub connector, automatic baud rate detection (up to 12 Mbps), and full cyclic I/O data exchange—making it an essential component for machine builders and system integrators deploying Vacon drives in PROFIBUS-controlled environments across water treatment, HVAC, material handling, and process industries.
