Mitsubishi Programmable Logic Controllers
The Mitsubishi’s FX3U series of programmable logic controllers (PLCs). It’s designed to provide high-speed input capabilities, specifically for applications requiring accurate counting or measurement of fast pulses.
Specifications:
- Product Type: High-Speed Input Adapter. It’s an expansion module, not a standalone PLC.
- Compatibility: Designed specifically for the Mitsubishi FX3U PLC series. It connects directly to the expansion bus of the FX3U main unit.
- Two-phase Input: This is its primary strength, allowing for accurate position and speed measurement from encoders.
- Comparison Operations: Allows setting up comparisons with internal PLC values for triggering actions.
- Programming: Configured and utilized within the GX Works2 (or GX Developer for older versions) programming software for the FX3U PLC
Typical Applications:
- Position Control: Reading feedback from incremental encoders on motors, conveyors, or other moving machinery for accurate positioning.
- Speed Measurement: Determining the speed of rotating shafts or moving objects using encoders or proximity sensors.
- Flow Rate Measurement: Interfacing with high-resolution flow meters that output pulse signals.
- Production Counting: Accurately counting small, fast-moving items on a production line.
Why it’s important:
Standard digital input modules on a PLC often have speed limitations. Applications involving encoders or sensors generating pulses at tens or hundreds of kHz, a dedicated high-speed input module like the FX3U-4HSX-ADP is indispensable.
