WGC-220 Series 2-channel Instrumentation Conditioner

Two-channel instrumentation amplifier offers fast sampling, real-time summation-difference operation between channels, and a wide range of control I/O functions. It is ideal for monitoring manufacturing line loads in the iron and steel industry, etc. Feature an intuitive touch panel and can save setting values and error logs (WGC-220A only) to an SD card. Support remote sensing for highly accurate measurement even when extending cables. Channels: 2 Sampling rate: 4000 times/sec.

Description

Features

  • Two-channel summation types with touch panel
  • Operation functions included
  • Variety of control I/O (input: 11, output: 15)
  • With one-side operation function (WGC-221A)
