Analog Input Module

Analog Input Module


The China UWNTEK UW5261 analog input module implements signal type selection, program-controlled amplification, data conversion, fault diagnosis, digital filtering, temperature compensation, linear correction, engineering conversion, etc. of a single analog input channel, and supports universal input and online replacement.

Analog Input Module Features:

Supports universal input of analog quantities (voltage/current/thermal resistance/thermocouple), with full range and high accuracy;

Automatically performs ambient temperature compensation and zero point and gain correction, no adjustment or maintenance required;

Online self-diagnosis and operating status display to quickly identify fault points;

Thermocouple signal automatic cold junction compensation, disconnection detection;

Complete isolation between modules and systems, and between modules, keeping external interference out;

Provides +24V/30mA isolated power distribution output to directly distribute power to on-site two-wire or three-wire transmitters, reducing supporting costs and engineering quantities, and significantly improving system anti-interference and stability;

Surge protection and online plug-in support circuit support module online plug-in and online replacement;

Low ripple, low temperature drift, high efficiency, high stability, high withstand voltage isolation power supply design, with multiple protections such as soft start, input short circuit protection, output power limit, and power distribution output current limit.
