Interface and Sensor Compatibility
Uses a European-style connector interface with two independent speed input channels, compatible with eddy current proximity probes (3300 XL) and magnetic pickup (magneto-electric) sensors.

Wiring and Signal Functions
Supports sensor signal input, 4–20 mA analog output, alarm relay outputs, and sensor buffer outputs. Employs single-ended, shielded grounding with an anti-interference design to ensure stable signal transmission in electrically noisy environments.

Communication Integration
Supports Modbus communication and Ethernet TCP/IP, enabling seamless integration with PLC/DCS systems and compatibility with SCADA and System 1 software for data exchange and system-level monitoring.

Environmental Specifications

• Operating temperature: −30 °C to +65 °C

• Relative humidity: 5% to 95%, non-condensing

Designed for reliable operation in harsh industrial environments.

Signal Conversion and Distribution
Provides reliable routing of eddy current and magnetic pickup sensor signals to the 3500/53 module, while offering buffered sensor outputs for secondary measurements, analysis, or external monitoring devices.

Alarm and Protection Outputs
Equipped with two independent alarm relay outputs capable of triggering shutdown or interlock protection actions. Fast response time makes the module suitable for emergency shutdown and overspeed protection applications.

Communication and Data Reporting
Uploads speed values, alarm status, and diagnostic information to SCADA and System 1 software via Modbus and Ethernet TCP/IP, supporting remote monitoring, event analysis, and fault diagnosis.

Wiring and Maintenance Convenience
Centralized external wiring management simplifies on-site installation, commissioning, and maintenance, reducing internal rack wiring complexity and improving system serviceability.
