1. Communication Protocol: DeviceNet network with configurable rates (125/250/500 Kbps via bus master).

2. Input Configuration: Dual tachometer inputs supporting ±25V (50 mA peak), Eddy current/Magnetic pickups, TTL devices (120 kΩ min impedance).

3. Speed Range: 1–2,000,000 RPM (0.0167–20,000 Hz frequency) with adaptive error tolerance (±0.2 RPM at 240 RPM to ±100 RPM at 2,000,000 RPM).

4. Analog Outputs: Two isolated 4–20 mA channels (300 Ω max load) programmable for speed/acceleration.

5. Buffered Output Ranges: Configurable voltage modes (-24V to +29V, -5V to +29V, -5V to +24V) with 5V CMOS redundancy.

6. Sensor Diagnostics: Fault detection for Eddy current transducers and Magnetic pickups.

7. Status Indicators: Dual-color LEDs for module (red/green), network (red/green), channel 2 (yellow/red), and auxiliary functions.

8. Measurement Capabilities: Directional rotation (forward/reverse), acceleration (RPM/min), and peak speed capture.

The 440-SPD02-01RB is a high-precision dual-channel speed monitoring module designed for industrial automation, combining DeviceNet configurability (125/250/500 Kbps) with ultra-wide RPM sensing (1–2,000,000 RPM) and adaptive error tolerance. Featuring dual isolated 4–20 mA outputs, configurable voltage buffering (-24V to +29V), and advanced diagnostics for Eddy/Magnetic pickups, the 1440-SPD02-01RB ensures robust performance in harsh environments, supported by real-time status LEDs and multi-functional measurement capabilities (directional rotation, acceleration, peak capture) for mission-critical machinery monitoring and control.
