VSV301 600-034 Vibration Monitoring Module
Description:
VSV301 is one of members of distributed monitoring system. As a monitoring module, VSV301 can protect the machinery with the trending and limit exceedance checks. It is can be mounted on machinery, compatible with the VSB300 terminal base. VSV301 is designed for condition monitoring and machinery protection applications, can be worked in hazardous locations.

VSV301 module delivers robust alarm and logic management capabilities, with each of its processed outputs equipped with 4 configurable alarms—each adjustable independently for hysteresis and time delay. To support comprehensive alarm and status aggregation, the VSV301 incorporates AND, OR, and majority voting logic functions, encompassing 4 basic and 2 advanced logical operations for flexible combination of alarm and status data. 

For discrete signal handling, the VSV301 features 4 dedicated discrete signal inputs, pre-assigned to functions including trip multiply, alarm bypass, and alarm reset, with 1 spare input reserved for flexible customization. Furthermore, the VSV301 is fitted with 2 local analogue outputs that support dual configurable modes: either as 4–20 mA DC current loop outputs or ±5V processed AC outputs, complemented by 2 local SPDT relay outputs to meet diverse on-site control and signal transmission requirements.

Features:
▪  2 individually configurable dynamic input channels with up to 19 kHz bandwidth for > accelerometers, proximity probes > dynamic pressure sensors > process sensors (current loop or voltage based) 
▪  1 auxiliary input channel for tachometer or quasistatic measurements
▪  Synchronous sampling across all input channels
▪  Synchronization accuracy (among modules within the same measurement block) better than 1 µs
▪  Real-time waveform and full-spectrum analysis supporting up to 1600-line FFT calculations per second
▪  Up to 20 processed output signals available per module

Q&A:
1. What's the operting temperature of VSV301?
The operating temperature is -20 to 70°C (-4 to 158°F), same as the terminal base VSB300.
2. What is the VSV301 monitoring module used for?
The VSV301 monitoring module is designed for monitoring, protecting, analyzing, and diagnosing critical rotating assets—including gas turbines, steam turbines, hydro turbines, and other similar rotating machinery.
