Fieldbus node BMX60

Product overview

Fieldbus torque interface module for rotary torque sensors. Measures torque (TMC), torque (frequency), rotational speed and angle. Includes CASMA filter and real-time power calculation. Integrated web server for parameterization. DIN-rail mounting with protective class IP20.

Connectivity

• OT (real-time fieldbus) support: Profinet, EtherCAT, Ethernet/IP, CANopen 2.0, Analog output (V/mA)
• IT support: MQTT, openDAQ, REST API

Key features

• Accuracy class: 0.01
• Measurements: torque (TMC), torque (frequency), rotational speed, angle, encoder inputs
• Channel capability: 1st channel frequencies up to 1 MHz (TMC support); 2nd channel two-track encoder with/without zero signal
• Sample and streaming rate: 40 kS/s per signal

Advantages

• Precise measurement: accuracy class 0.01 and dual-range linearization for full/partial-range measurement
• High dynamics: supports high measurement rates on the fieldbus side (up to 2 kHz)
• Fast deployment: integrated web server for configuration and diagnosis, signal line writer
• Simple configuration: parameterization without additional software
• Flexible networking: simultaneous transmission of torque and speed to separate OT and IT networks
• Torque input: TMC (Torque Measurement Communication) digital interface and frequency input
• Speed input: supports integrated speed measurement from HBK torque transducers and external speed sensors

Engineering benefits

Reduces hardware requirements, integration effort and system complexity while providing deterministic real-time performance and high-resolution data for analysis and monitoring. Supports efficient, future-proof system design.

Conclusion

The BMX60 is a compact DIN-rail solution for torque measurement applications combining precise measurement, deterministic fieldbus performance and wide OT/IT connectivity.
