Mitsubishi A1S68AD MELSEC-A Series 8-channel Analog Input Module

Mitsubishi A1S68AD belongs to MELSEC-AnS/QnAS series A/D converter module, 8 analog input channels, 16-bit signed binary conversion. It supports mixed voltage and current signal on separate channels, selectable ranges including -10~+10V, 0~10V, 1~5V, 0~20mA, 4~20mA. Each channel can be individually enabled or disabled, supporting sampling or average filtering mode. 0.5ms per channel maximum conversion speed, optocoupler isolation between external analog circuit and PLC backplane. Widely used for legacy process monitoring, pressure, flow and temperature signal acquisition in old packaging, textile and machine tool control systems for maintenance and spare replacement.
