The General Standards PMC-ADADIO-312 is a 12-channel analog I/O PMC card engineered for high-performance data acquisition and real-time control systems. It integrates eight 16-bit analog input channels, four 16-bit analog output channels, and an 8-bit bidirectional digital I/O port with two control lines. The card delivers simultaneous analog input sampling across all channels with a maximum aggregate rate of 1,600,000 samples per second, supported by a 32K-sample FIFO buffer. Analog output channels support synchronized updates via hardware or software strobe at rates up to 250K samples per second. Factory-configured input/output ranges include ±10 V, ±5 V, or ±2.5 V.
