K4LCN-16 51403519-160 Honeywell Industrial Control Board Memory Processor Card
The Honeywell K4LCN-16, with official manufacturer part number 51403519-160, is a high-reliability 16-channel digital output (DO) module engineered for use in Honeywell Experion® PKS (Process Knowledge System) and Safety Manager control platforms. Designed for mission-critical industrial automation, this module delivers robust, isolated switching capability to control solenoids, motor starters, relays, alarm beacons, and other field devices in oil & gas, refining, chemical processing, power generation, and water/wastewater facilities.
As part of Honeywell’s advanced I/O architecture, the K4LCN-16 / 51403519-160 supports channel-level diagnostics, galvanic isolation, and hot-swap capability when installed in a redundant I/O carrier (e.g., CC-PAK04). It features sourcing (PNP-type) outputs that switch 24 V DC signals to field loads, ensuring compatibility with standard industrial actuators and interlock systems. The module also provides LED status indicators per channel, enabling rapid troubleshooting during commissioning or maintenance.
