The Acromag IP320 is a 12-bit analog-to-digital input module engineered for high-density data acquisition in industrial process control, monitoring, and automation systems. It combines 40 single-ended or 20 differential input channels with successive approximation conversion at 8.5 µS per sample, delivering up to 100K samples per second. Four modules can cascade on a single carrier board for up to 160 single-ended inputs, making it ideal for distributed I/O applications requiring precision analog measurement across multiple voltage ranges and gain settings.
