Module 7 kênh đầu vào RTD ICP DAS I-87015PW-G CR
Feature
• 7-channel RTD Input
• 3-wire RTD Lead Resistance Elimination
• High Resolution: 16-bit
• Individual Channel Configuration
• Open Wire Detection
• Overvoltage Protection
Introduction
The I-87015PW is specially designed for long-distance RTD measurement, and features automatic compensation function for three-wire RTD, so it can be accurately measured regardless of the wire length. It is a 7-channel RTD input module for measuring temperature using RTD. Each channel can be connected to a different kind of RTD sensor, which provides high overvoltage protection of 120 VDC, and also has an open circuit detection function for each channel of the RTD input. The module is fully RoHS compliant and has 4 kV ESD protection and 3000 VDC module internal isolation.
