Module RS-485 DCON 8 kênh đầu vào tương tự AI (Dòng điện) ICP DAS I-7017RC CR
Features
- Current Input Only
- Built-in Resistor to Simplify Current Measurement
- Adjustable Sampling Rate (Fast/Normal Mode)
- Open Wire Detection for 4 ~ 20 mA input
Introduction
The I-7017C is an 8-channel current input module that is specifically designed to measure current only. Its user-friendly design saves both time and effort when measuring a current thanks to a built-in resistor, meaning that you can now measure current directly. The I-7017RC is an upgraded version of the I-7017C, with the only difference being that the I-7017RC is much more suitable for critically harsh environments. The I-7017RC also has 4 kV ESD protection and +/- 200 VDC common voltage as current input protection, and also features 3000 VDC intra-module isolation and open wire detection for 4 ~ 20 mA input. The sampling rate of the I-7017RC and I-7017FC is adjustable, meaning that either fast mode or normal mode can be selected. The M-7017C and M-7017RC has the same specifications as the I-7017C and M-7017RC, but provides additional support for the Modbus RTU protocol as well as the DCON protocol
