Key Features and Engineering Advantages

• High-Density Monitoring: Two independent channels in a single slot maximize rack usage without sacrificing the individual configuration flexibility of each vibration loop.

• API 670 Compliance: Fully meets the American Petroleum Institute's standards for machinery protection, ensuring the highest level of reliability for critical plant assets.

• Buffered Diagnostics: Integrated front-panel buffered outputs allow for detailed diagnostic "deep dives" using portable analyzers without the risk of accidentally tripping the machine.

• Programmable Protection: Supports highly customizable alarm setpoints for both "Alert" (maintenance warning) and "Danger" (automatic shutdown) levels.

• Universal Input Support: Compatible with both eddy-current proximity probes and seismic velocity transducers, making it adaptable to a wide range of machinery types.
