Honeywell SC-UCNN11 ControlEdge RTU2020 Redundant Controller Module

Description

Designed to deliver high-availability control in demanding remote environments, the Honeywell SC-UCNN11 functions as a processing unit within the ControlEdge RTU2020 redundant controller system. This hardware module provides dual-redundant, hot-standby processing capabilities to ensure seamless failover and uninterrupted process monitoring, eliminating single points of failure in critical automation applications.

The module is engineered for deployment in remote or hostile sites, offering low power consumption profiles optimized for solar or battery-backed installations. It interfaces directly with associated input/output modules (IOMs) to provide real-time process control, robust communication, and data logging capabilities across distributed networks.

Features

• Dual-redundant architecture ensures high-availability operation and automatic bump-free switchover.
• Low-power design minimizes overhead, making it ideal for remote sites with limited power infrastructure.
• Compatible with ControlEdge RTU2020 I/O expansion modules for scalable site automation.
• Wide DC input voltage tolerance accommodates standard battery-charging variations.
• Integrated hardware diagnostics monitor power states and processing health.

Applications

• Oil and gas pipeline monitoring and control
• Wellhead automation and custody transfer systems
• Water and wastewater remote pump station management
• Environmental monitoring and remote terminal unit (RTU) installations

Installation Guidelines

For reliable and safe operation, mount the module securely within an enclosure that provides adequate protection against dust, moisture, and extreme environmental variables. Ensure standard 24 VDC power lines are correctly fused and filtered. Grounding must follow standard industrial electrical practices to mitigate the risk of electromagnetic interference (EMI) or voltage surges. Maintain appropriate physical clearance around the unit to allow natural convective cooling.
