Bently Nevada 2201/03-01 (PWA1000784-01R) is a 4-channel vibration monitoring module manufactured by Bently Nevada, a subsidiary of GE. Specifically designed for the Allen‑Bradley PLC‑5 system, it enables continuous condition monitoring of critical rotating machinery. The module can acquire four vibration and displacement signals simultaneously and features two-level alarms (alert and danger). It serves as a core component for predictive maintenance of industrial equipment.
Product Advantages
Native Compatibility with PLC-5It can be directly installed into Allen-Bradley PLC-5 racks without additional gateways, cutting integration costs and reducing communication latency.
Four Independently Programmable ChannelsA single module supports four monitoring points and mixed measurement of vibration, displacement, eccentricity and other parameters, saving rack space.
Industrial-grade High ReliabilityDesigned for wide temperature operation and strong electromagnetic interference resistance to withstand harsh working conditions. Its MTBF exceeds 100,000 hours.
Simplified MaintenanceConfiguration is completed via software instead of traditional jumpers. It supports remote parameter setting and fault diagnosis to minimize downtime.
High-precision MeasurementFull-scale accuracy reaches ±0.5%. Matched with Bently Nevada 3300 series sensors, it delivers excellent signal stability.

FAQ
Q: What are the core differences between 2201/03-01 and 3300/03-02?A: The 2201/03-01 is engineered exclusively for PLC-5 and can be mounted directly into the rack, delivering high cost performance. The 3300/03-02 is a standalone system with more comprehensive functions, yet it requires an additional rack and entails higher costs.
Q: Is it compatible with non-Bently sensors?A: It works with third-party sensors that output standard 4~20 mA / 0~10 VDC signals. For optimal accuracy and stability, Bently 3300 series sensors are recommended.
Q: What is PWA1000784-01R?A: PWA1000784-01R refers to the circuit board part number of 2201/03-01, which indicates genuine original products. Please verify this number during procurement to avoid refurbished units.
Q: The OK indicator flashes. How to troubleshoot?
- Check the sensor wiring for short circuits or open circuits.
- Verify parameter settings for range mismatch.
- Measure the supply voltage to ensure it is not lower than 5 VDC.
Q: No data displayed on the channel?
- Confirm the sensor is powered normally.
- Check if the input terminal wiring is securely connected.
- Reboot the module and re-download configuration parameters.
Q: Alarms are triggered frequently. How to optimize?
- Appropriately raise the alert threshold to prevent false alarms.
- Check the mounting gap of eddy current probes (standard range: 0.5~1.5 mm).
- Set the filter frequency to 1 to 2 times the equipment rotational speed.
Q: How to back up and restore parameters?A: Connect to the module via 2201 Config Tool and save parameters to a file using the backup function. When replacing the module, simply restore the saved file without reconfiguring manually.
