HP 395566-003
Product Name
HP 395566-003 isolated analog input module.
Product Introduction
The 395566-003 is an industrial isolated analog input module designed for automation systems that require galvanic isolation between field sensors and control electronics. It acquires voltage or current signals and transmits conditioned data to the host controller.
Detailed content
Technical Specifications
Input type is isolated voltage or current. Input range covers 0 to 10 volt or 0 to 20 milliampere. Module current rating is 2 ampere total field power per the assigned power class. Operating temperature is -40 to 85 degrees Celsius. Storage temperature is -40 to 85 degrees Celsius. Relative humidity tolerance is 95 percent non-condensing. Operating altitude is up to 5000 meters. Dimensions are 100 by 100 by 40 millimeters. Weight is approximately 250 grams.
Functional Features
Channel isolation suppresses ground loops and electromagnetic interference. The module supports DIN-rail mounting, standard industrial analog scaling, and continuous signal measurement for supervision or closed-loop control.
Material Composition
The enclosure uses industrial-grade insulating polymer. Internal circuitry uses FR-4 printed-board material, isolated signal transformers or optocouplers, metal film resistors, and tin-plated terminals.
Structural Characteristics
The device is a compact DIN-rail module with screw or spring terminals, isolated input stage, signal-conditioning section, and standard industrial bus or direct-wiring output.
Working Principle
The field signal enters the isolated front end. Isolation barriers separate field ground from controller ground. Conditioning circuits filter, amplify, and convert the signal, then the output stage provides standardized data or voltage/current representation to the control system.
Installation Requirements
Mount on a standard DIN rail inside a control cabinet. Use separate cables for power, input, and output wiring. Maintain clearance for ventilation. Torque terminals to the manufacturer-recommended values and verify grounding separation.
Usage Precautions
Do not exceed 0 to 10 volt or 0 to 20 milliampere input limits without external shunts or dividers. Avoid condensation and conductive dust. Confirm isolation voltage rating before connecting mixed-ground systems. Perform annual calibration checks in critical process applications.
