1746SC-INI4VI

The 1746SC-INI4VI from Allen Bradley fulfills the role of an isolated analog input module within the SLC 500 series. It supports four channels, allowing for the monitoring and measurement of various analog signals, enhancing the system's versatility. Each input undergoes conversion through the sigma-delta method, which aids in producing accurate digital representations of the incoming signals.

This module consumes 2.75 kW of power from the backplane and draws 570 mA, ensuring it operates efficiently within its designated slot in the 1746 I/O chassis. Additionally, it incorporates programmable notch filters to filter input signals effectively, contributing to a high normal mode rejection rate of 98 dB at both 50 and 60 Hertz. For reliable operation, automatic calibration is performed every 10 seconds, promoting consistent accuracy across multiple applications.

Thermal dissipation is managed at 3.25 W, indicating the component's capacity to handle heat generated during usage. The design also accommodates installation altitudes of up to 1000 meters above sea level, enhancing its deployment in various environments. This combination of features makes the 1746SC-INI4VI a robust choice for integrating isolated analog inputs in control applications.
