Bently Nevada 135489-02 3500/42 Internal Barrier I/O Module

Bently Nevada 135489-02 3500/42 Internal Barrier I/O ModuleConfigured for intrinsically safe transducer interfacing within Bently Nevada 3500 Series Machinery Protection Systems, the Bently Nevada 135489 02 (3500 42 Internal Barrier I O Module) provides direct physical electrical execution. The hardware operates as a four channel isolated interface that restricts electrical energy routing into hazardous areas while conditioning incoming sensor signals. Paired directly with the 3500 42M Proximitor Seismic

Feature Details Manufacturer Yokogawa Electric Corporation Model Number AAI543-S00 Product Type Analog Output Module Series CENTUM VP / CS 3000 (FIO Subsystem) Number of Channels 16

Predictive maintenance strategies

With integrated dual Ethernet and serial interfaces

This passive component mounts onto the leftmost edge of a 1769 backplane assembly to close the 5 VDC communication bus loop and suppress signal voltage reflections

Mixed Logic Compatibility: Supports 5V RS422 differential signals and 24V HTL levels

allowing for deterministic response times required for safety-critical interlocks

Total Power Output: 48 W (Typical)

Signal Separation: Maintain physical separation between the low-voltage 4-20 mA / VDC transceiver signal lines and high-voltage AC power or discrete inductive switching lines within the wire ducting

to ensure consistent noise attenuation

operates as a dedicated hardware component for fail-safe speed monitoring within gas

Q: What sensors are supported

It features universal conditioning circuitry compatible with passive magnetic pickups (MPU)
