Acromag IP341 14-Bit Simultaneous A/D Conversion Analog Input Module

The Acromag IP341 is a 14-bit simultaneous analog input module delivering high-resolution data acquisition across 16 differential channels in industrial environments. Eight integrated 14-bit ADCs enable true simultaneous sampling of paired 8-channel banks, with conversion completed in 8 µS per bank or 16 µS for all 16 channels. Maximum throughput reaches 1 MHz across all 16 channels, supporting demanding signal measurement and logging applications requiring precision and speed.
