Allen-Bradley 1769SC-IF4IH Compact I/O 4-Channel Analog + HART Input Module

Description

The Allen-Bradley 1769SC-IF4IH is a high-performance analog input module belonging to the Compact I/O (1769 Series) family. This 4-channel module supports both analog and HART input functionality, with the “IH” designation indicating high-resolution current input capability. It accepts a range of input types, including current signals (0-20 mA, 4-20 mA) and voltage signals (±10 V, 0-10 V), making it versatile for diverse industrial sensing applications.

Key features include auto-calibration, which activates automatically when a channel is first enabled or when its configuration is modified, ensuring consistent measurement accuracy. Users can wire each of the 4 channels as either single-ended or differential inputs, adapting to different sensor wiring setups. Notably, the module does not provide loop power for analog inputs, requiring a separate power supply matched to the input transmitter’s specifications.

Designed for seamless integration, the 1769SC-IF4IH is optimized for use with CompactLogix or MicroLogix control systems, delivering precise signal processing and accurate sensor readings to support machine and factory automation optimization. Its compact, space-saving design makes it ideal for installation in tight control panel environments, while its isolated construction enhances reliability in industrial settings.
