1734SC-IF4U

Overview of Allen Bradley 1734sc-IF4U

The Allen Bradley 1734sc-IF4U is a universal analog input module designed for direct integration with Allen Bradley Point I/O systems. Manufactured by Spectrum Controls, an Allen Bradley Encompass Partner, this module offers high flexibility by supporting voltage, current, RTD (Resistance Temperature Detector), resistance, and thermocouple inputs in a single unit. With four independent input channels, the 1734sc-IF4U can be configured for a variety of industrial signal types, including standard voltage and current ranges, as well as direct connection to J, K, T, and E type thermocouples, multiple RTD types (PT385, PT3916, Ni618, Ni672, NiFe518, Cu426), and resistance ranges. Its compact form factor and advanced signal processing make it suitable for applications demanding precision and adaptability in control systems.
