Specifications

The 8-channel analog input modules AD318/AD328/AD338 will convert the external
analog signal (voltage or current) into digital data.
The AD318/AD328/AD338 have the following features:
(1) 2.45 ms high-speed conversion using 8-channels
(2) Isolated each channel
• Provides 8 analog data points per module to function as 8 word type input module.
• Has a built-in multiplexer and reads input data at 2.45 ms cycle using 8 channels,
performs A/D conversion, and stores the result into controller internal memory by
batch I/O or direct input.
