Y31
4CH 16bit 0~20mA / 4~20mA Analog Input Module
The Y31 analog input modules are among the Y series I/O modules for IOy series and ARMxy series products.This module has 4 input channels, namely AI1, AI2, AI3, and AI4, which can receive 0…20mA / 4…20mA current control signals.The input signals of each channel are electrically isolated and then converted into digital signals, which are transmitted with a 16-bit resolution.
