Description
The 3500/20 125744-02 Standard Rack Interface Module serves as the primary interface to Bently Nevada™ 3500 racks, providing front panel RS232 or RS422 serial communications at 38.4 k baud (serial) and 14.4 k baud (internal modem). The 3500/20 125744-02 Standard Rack Interface Module consumes 4.75 W typical power and includes front panel OK, TX/RX, TM, and CONFIG OK LEDs for rapid operational monitoring. Equipped with a 5A I/O module OK relay at 24 Vdc/120 Vac (120 W / 600 VA), the 3500/20 125744-02 Standard Rack Interface Module supports Trip Multiply, Alarm Inhibit, and Rack Reset system contacts. Cable length reaches 30 m for RS232, 1200 m for RS422, and 3 m for external data manager connections. Operating at 0°C to +50°C and storing at -40°C to +85°C with 95% non-condensing humidity, the 3500/20 125744-02 Standard Rack Interface Module integrates with TDXnet, TDIX, and DDIX communication processors for static and dynamic data collection. For TMR configurations, the 3500/20 125744-02 Standard Rack Interface Module performs monitor channel comparisons, continually validating outputs from three redundant monitors. Designed for automated machinery monitoring, the 3500/20 125744-02 Standard Rack Interface Module enables reliable data acquisition, configuration, and event tracking in industrial automation systems.
Applications
Connect 3500 Rack Data to PLC and SCADA Systems
The 3500/20 125744-02 Standard Rack Interface Module transmits data at 38.4 k baud (RS232) or 14.4 k baud (internal modem), providing real-time static and dynamic signals to PLCs or SCADA systems. Its RS422 communication supports distances up to 1200 m, enabling integration with remote industrial automation systems.
Collect and Compare Redundant Monitor Outputs
In TMR configurations, the 3500/20 125744-02 Standard Rack Interface Module continuously compares outputs from three redundant monitors. By detecting deviations beyond a configured percentage, it flags errors in under 13 seconds and logs events for predictive maintenance scheduling.
Control Rack Functions Remotely Using System Contacts
The 3500/20 125744-02 Standard Rack Interface Module manages Trip Multiply, Alarm Inhibit, and Rack Reset actions via 5A I/O module OK relays at 24 Vdc/120 Vac. These numeric ratings ensure reliable remote control of rack functions without additional relays.
Extend Data Acquisition to External Communication Processors
With support for TDXnet, TDIX, and DDIX processors and 3 m maximum external cable length, the 3500/20 125744-02 Standard Rack Interface Module enables automated collection of machinery vibration and temperature data for real-time condition monitoring.

Competitive Advantage
High-Speed Data Transmission
The 3500/20 125744-02 Standard Rack Interface Module supports 38.4 k baud (RS232) and 14.4 k baud (modem) data rates, ensuring fast and accurate delivery of static and dynamic measurements from the 3500 rack.
Long-Range Industrial Connectivity
With RS422 support up to 1200 m, the 3500/20 125744-02 Standard Rack Interface Module enables reliable communication between the rack and remote processors, reducing signal loss over extended distances.
Rapid Error Detection in Redundant Systems
By performing continuous monitor channel comparisons, the 3500/20 125744-02 Standard Rack Interface Module detects deviations among three monitors in TMR setups, supporting maintenance actions before machinery failure occurs.
Robust Electrical Control
The 3500/20 125744-02 Standard Rack Interface Module features 5A I/O module OK relays rated at 24 Vdc/120 Vac (120 W / 600 VA), allowing direct control of rack alarms and reset operations without external relays.
Simplified Installation and Operation
Slot 1 placement in the 3500 rack, front panel LEDs, and address switches make the 3500/20 125744-02 Standard Rack Interface Module quick to install and configure, with numeric status indicators for rapid operational assessment.
