The 1769-IQ16F is a 16-point high-speed digital input module for 24 V DC industrial sensors and switching devices.
Its main difference from a standard digital input module is faster input response combined with configurable filtering. This makes it suitable for detecting short-duration signals from proximity switches, photoelectric sensors and high-cycle machine mechanisms.
The module accepts both sinking and sourcing input wiring and divides the 16 channels into two groups of eight points.
Key Features
- 16 high-speed digital inputs
- 24 V DC sink/source compatibility
- Two isolated groups of eight points
- Configurable input filtering
- Fast sensor-signal detection
- Compact DIN-rail installation
Typical Applications
- High-speed proximity sensors
- Photoelectric detection
- Packaging machine counting
- Conveyor position sensing
- Rapid machine-event monitoring
High-Speed Input Function
The F suffix identifies the high-speed input version.
Compared with a standard input module, it is better suited to:
- Short sensor pulses
- Fast product counting
- Rapid position detection
- High-cycle machine sequences
Configurable Input Filtering
The digital filter can be adjusted to balance response speed and noise rejection.
A shorter filter supports faster signal detection, while a longer filter helps reduce false input changes caused by electrical noise or contact bounce.
Sink and Source Compatibility
The module supports compatible sinking or sourcing field-device wiring.
Before installation, confirm:
- Sensor output polarity
- Common-terminal wiring
- Input voltage
- Field power supply
- Selected filter setting
