Product Overview & Description
The 3500/42M 140734‑02 + 128229‑01 module is a dual-card configuration in a rack-mounted machinery protection system designed to monitor proximity (displacement) and seismic (vibration) signals. The 140734‑02 front card performs signal conditioning from proximity and seismic transducers, measuring parameters such as radial vibration, axial displacement, differential expansion, eccentricity, acceleration, velocity, shaft absolute position, and circular acceptance region. The 128229‑01 rear card provides an internal I/O interface with built‑in terminations for straightforward field wiring, alongside configurable user-programmable alarms based on the conditioned signals.
This module is engineered for industrial robustness—supporting rack integration, high accuracy, and simplified installation, making it well-suited for protecting rotating machinery like turbines, compressors, pumps, and motors in critical environments.

Applications
This module is ideal for industrial real-time monitoring of rotating machinery such as turbines, generators, compressors, and pumps. It tracks displacement, vibration, velocity, and acceleration through proximity and seismic sensors, enabling early detection of misalignment, imbalance, bearing wear, and thermal expansion. Its compact design and automated alarm capabilities allow seamless integration into control systems, DCS, and predictive-maintenance architectures. The internal termination simplifies wiring, reducing installation time in high-volume or hazardous areas.
Advantages
-
Full-spectrum monitoring: Covers key parameters—vibration, displacement, acceleration, velocity—all in one module.
-
Accurate and reliable: Low-power design (<10 W), supports 4–20 mA outputs for precise recording and trending.
-
Compact yet robust: Stainless steel build ensures durability; IP-rated enclosure protects from dust and moisture.
-
Simplified installation: Internal termination reduces complexity and improves signal clarity.
-
Flexible interfacing: Analog, digital (Modbus RTU, Ethernet/IP), and alarm outputs support versatile integration.
-
Wide operating range: Operates reliably in –40 °C to +70/85 °C environments with high humidity tolerance.
