The Honeywell K4LCN-16 is a digital input/output module used within the Honeywell Experion PKS (Process Knowledge System) or C300 controller systems. This module is designed to interface with field devices and handle digital signals in industrial automation processes, particularly in process control and monitoring systems.

Product Name:

Honeywell K4LCN-16 Digital Input/Output Module

Product Description:

The Honeywell K4LCN-16 module is designed to provide 16 discrete I/O points for industrial control systems. It can be used for monitoring and controlling devices such as switches, sensors, relays, and other digital field instruments. The module supports both input and output operations, allowing it to process and interface with digital signals from process equipment.

This module is compatible with Honeywell’s C300 controller in a Distributed Control System (DCS) architecture and is particularly useful in critical process environments where reliability and precision are required.

Product Parameters and Specifications:

• I/O Type: Digital (Discrete)
• Number of Channels: 16 channels (16 Inputs or 16 Outputs, configurable)
• Input Voltage: 24 VDC typical (depending on field device specification)
• Output Voltage: 24 VDC or dry contact, depending on configuration
• Signal Type:
  • Digital Input: 24 VDC discrete signals
  • Digital Output: Can be relay outputs or 24 VDC signals
• Communication Interface: LCN (Local Control Network), designed to integrate into Honeywell’s control systems like Experion PKS
• Bus Type: LCN Bus (for communication with controllers and other modules)
• Isolation: Typically isolated inputs and outputs to protect against electrical surges and noise

• Mounting: DIN rail mounting for ease of installation in industrial cabinets
• Enclosure Type: Industrial-grade, typically IP20 rated (suitable for indoor use)

Product Use:

The Honeywell K4LCN-16 module is primarily used in process automation and control systems for industrial applications. Some common uses include:

1. Digital I/O interfacing: Monitoring and controlling digital devices such as:
   • Sensors (e.g., limit switches, proximity sensors)
   • Push buttons or other human-machine interface (HMI) devices
   • Relays and solenoids for automation control
2. Process Control: Used in systems that require real-time digital signal processing, such as in chemical, oil & gas, or manufacturing plants.
3. Alarm and Status Monitoring: Digital input signals can be used for alarm conditions, while outputs can control devices to manage alarms or signals.
4. Discrete Event Control: Handling on/off signals from various industrial control systems for activities like valve actuation, equipment status monitoring, or safety interlocks.
