Imagine a factory line that stops because a sensor signal is missed. The delay costs time and money. The MELSEC-Q QX80 Digital Input I/O Module is made to catch every signal reliably. It lets you connect up to 16 DC inputs to a Mitsubishi PLC and turn raw signals into clear data. If you need fast, accurate input handling, this module removes the guesswork and keeps your equipment running.
MELSEC-Q QX80 Digital Input I/O Module
Many automation projects suffer from noisy or slow input reading. When a machine does not know whether a switch is on or off, it may halt or produce defects. This problem matters because downtime hurts productivity and quality. The QX80 solves the issue by offering 16 isolated input points, adjustable response times, and built-in LED status. It fits directly into the MELSEC-Q series, so you get a clean, plug-and-play solution without extra wiring or programming tricks.
Benefits
- Fast response from 1 ms to 70 ms lets you catch rapid events.
- Photocoupler isolation protects your PLC from voltage spikes.
- LED indicator shows real-time input status for quick troubleshooting.
- 16 points in one module reduce cabinet space and wiring complexity.
- Wide voltage range (19.2 V-28.8 V) works with most 24 V systems.
Usages
The QX80 is ideal for conveyor belt sensors, emergency stop buttons, limit switches, and temperature alarm contacts. It fits in packaging machines that need to read dozens of on/off signals. In a water treatment plant it can monitor valve positions and pump status. Any application that requires reliable digital inputs and fast reaction will benefit from this module.
