Honeywell K4LCN-16 51403519-160 Digital input module
Honeywell K4LCN-16 51403519-160 is an industrial-grade digital input module designed for TDC 3000 distributed control systems, used to collect discrete signals in industrial sites. The module adopts independent channel isolation design, supports dry contact, wet contact and other digital signals access, and can convert status signals of on-site equipment (such as valve switch, equipment running status) into digital quantities for transmission to the controller. It has high anti-interference and stability, suitable for petrochemical, manufacturing and other scenarios with high requirements for discrete monitoring.

Product Performance
- High-speed signal response: Response time within 1ms can accurately capture the state changes of on-site equipment, ensuring real-time monitoring of valve switching, motor start-stop and other actions, meeting the requirements of fast control.
- Strong anti-interference ability: 2500V AC isolation design between channels and with power supply effectively suppresses electromagnetic interference and ground loops in industrial sites, with signal transmission accuracy up to 99.99%.
- Flexible signal adaptation: Supports both dry contact and wet contact input modes, and can connect limit switches, proximity sensors and other devices without additional conversion components, reducing system integration complexity.
- Wide-temperature stable operation: Maintains stable signal acquisition performance within -20°C to +60°C, and runs without failure in 5%-95% humidity (non-condensing) environment, adapting to high and low temperature, humid industrial environments.
- Convenient maintenance design: Supports online hot-swap replacement, LED indicators on the module surface display power and each channel status (normal/fault) in real time, and with system diagnostic functions, fault location time is reduced to within 5 minutes.
