The Bently Nevada 135489-01 Internal Barrier I/O Module is designed to provide intrinsic safety and seamless integration with the 3500 Machinery Protection System. This module supports four proximity or accelerometer channels and features internal terminations, offering both performance and protection in hazardous environments.

Unlike external barriers, the internal barrier design ensures there is no performance degradation, allowing for accurate monitoring and reliable data collection. The 135489-01 module complies with international safety standards, removing the need for individual certification and simplifying system deployment.

Ideal for use in areas requiring explosion protection, this module is fully compatible with hazardous-area approved Bently Nevada transducer systems. It allows you to upgrade standard 3500 monitors by simply replacing the I/O module—no system redesign required.
