Acromag IP220A-16 12-Bit Analog Output Industry Pack Module

The Acromag IP220A-16 is a 12-bit analog output Industry Pack module that delivers 16 independent voltage output channels for industrial automation and precision control systems. Each channel features its own 12-bit Digital-to-Analog Converter (DAC), eliminating glitches inherent in multiplexed designs. The module operates in a bipolar output range of -10V to +10V with ±0.025% system accuracy at 25°C (unloaded).

Double-buffered architecture enables flexible update modes - individual channel writes or simultaneous multi-channel triggers - making it ideal for applications requiring synchronized linear movements or coordinated multi-axis control.
