VSE903 is decentralised diagnostic electronics for continuous vibration monitoring. Its IP67 housing supports installation outside conventional control cabinets. Four dynamic sensor inputs support simultaneous vibration acquisition. Ethernet TCP/IP communication enables network-based diagnostics. Standard M12 connections simplify field installation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VSE903 brings vibration diagnostics closer to the machine. Four dynamic inputs accept signals from vibration sensors. Additional process inputs support pulse and 4…20 mA signals. The controller can operate in demanding industrial environments. Its IP67 housing supports decentralised installation.
Dynamic inputs support 0…10 mA, IEPE and 4…20 mA signals. The dynamic measurement path provides 16-bit resolution. Sampling reaches 100 kSamples/s. Two process inputs support additional machine information. This enables combined vibration and process monitoring.
VSE903 provides Ethernet communication using TCP/IP. M12 connections provide robust field-level connectivity. The unit can communicate with higher-level diagnostic systems. VES004 is used for parameter setting. Historical data is retained internally.
