Product Details
Product Overview
The 1769sc-OF4IH acts as a high-performance 4-channel analog output module that integrates seamless HART (Highway Addressable Remote Transducer) connectivity within the Compact I/O™ platform. This module enables users to bridge the gap between traditional 4-20mA control and modern intelligent device management. By capturing real-time diagnostic and process data from smart field instruments, it serves as the backbone for advanced asset management strategies. We offer this unit as 100% Brand New and factory-original, providing a reliable foundation for mission-critical process loops.
Part Number Breakdown

Engineering Advantages
-
Elimination of External Bridges: This module communicates directly with HART-enabled field devices through existing 4-20mA wiring. This architecture removes the need for external multiplexers, bridge devices, or manual hand-held communicators, significantly reducing system complexity and installation costs.
-
Real-Time Predictive Maintenance: The 1769sc-OF4IH extracts device-specific health data and secondary process variables. Engineers use this information to predict instrument failure before it occurs, shifting maintenance from reactive to proactive.
-
Streamlined Integration: Full DTM (Device Type Manager) support allows the module to interface directly with your plant's asset management software. This creates a unified environment for configuring, calibrating, and troubleshooting field instruments from the control room.
-
Corrosive Environment Readiness: For facilities facing high humidity or chemical exposure, the available Conformal Coated (K) version provides a specialized protective layer. This prevents board-level corrosion and electrochemical migration, extending the module's MTBF (Mean Time Between Failures) in extreme conditions.
FAQs
-
Does the 1769sc-OF4IH require additional power supplies for the HART link?
No. The module utilizes the same loop power as the standard analog signal to carry the HART digital frequency. It draws its logic power directly from the 1769 backplane.
-
Can I use this module with standard 4-20mA actuators that do not support HART?
Yes. The module functions as a high-precision, standard analog output module. You simply gain the additional benefit of HART data if and when you connect "smart" field devices to the channels.
-
What is the advantage of the Conformal Coated "K" version?
The "K" version (1769sc-OF4IHK) applies a technical film to the PCB. If your installation resides near wastewater treatment, chemical processing, or salt-air environments, the coating prevents moisture and gases from degrading the copper traces.
-
Is technical support included with this module?
Every Brand New unit integrates seamlessly with Rockwell Automation’s ecosystem and qualifies for TechConnect™ support to assist with configuration and hardware integration.
