The Acromag IP236-8 is a 16-bit Digital-to-Analog output module delivering eight independent analog voltage channels for industrial control and automation systems. Each channel includes a 128-sample FIFO buffer with dedicated clock, enabling independent conversion rates, seamless waveform updates, and flexible triggering via software, external, or internal timer control. Output ranges are jumper-selectable at ±5V, ±10V, or 0 to 10V with maximum accuracy of ±0.0061% of 20V span (calibrated, 25°C, unloaded). The module achieves 100 kHz throughput across all eight channels and supports continuous, single, and external trigger modes for precise signal generation and synchronization across multiple modules.
