Description
Product Name: 1769sc-IF4IH Allen Braley Programmable controller
Product details:
The 1769sc-IF4IH is a specialized analog input module manufactured by Spectrum Controls for use with the Allen-Bradley CompactLogix and MicroLogix 1500 systems. It is part of the “sc” (specialty card) series, providing integrated HART (Highway Addressable Remote Transducer) protocol capability.
Product Overview
The 1769sc-IF4IH is a 4-channel, high-resolution analog input module that supports both current and voltage signals while allowing for seamless communication with HART-enabled field devices. It eliminates the need for external HART multiplexers or separate handheld communicators for configuration and monitoring.

Key Advantages
-
Integrated HART Connectivity: Access device IDs, diagnostics, and secondary variables directly within the Logix control system without additional hardware.
-
Asset Management: Compatible with FDT/DTM software and FactoryTalk AssetCentre, allowing for remote calibration and health monitoring of instruments.
-
High Precision: The 16-bit resolution ensures highly accurate data acquisition for demanding process control applications.
-
Space & Cost Savings: By combining analog I/O and HART communication in a single slot, you reduce cabinet space and wiring complexity.
-
Mixed Input Support: Channels can be individually configured for either voltage or current, providing flexibility for varied sensor types.
Important Considerations (Notes)
-
Power Supply: Ensure the 1769 backplane power supply has sufficient capacity for the 24V DC current draw required by this module.
-
HART Resistance: When using 4-20mA loops for HART communication, ensure the loop impedance is between 230 $\Omega$ and 600 $\Omega$ for reliable signal modulation.
-
Configuration: The module requires specific Add-On Profiles (AOP) or Configuration Software from Spectrum Controls to enable full HART functionality within RSLogix 5000/Studio 5000.
-
Wiring: Use shielded twisted-pair cable to minimize electromagnetic interference on sensitive analog signals.
Common Applications
-
Chemical Processing: Monitoring pressure and temperature transmitters where real-time diagnostics are critical for safety.
-
Oil & Gas: Remote monitoring of wellhead instrumentation and flow meters.
-
Water/Wastewater: Managing chemical dosing pumps and level sensors that require periodic parameter adjustments.
-
Predictive Maintenance: Utilizing HART data to track valve wear or sensor drift before a failure occurs.
