The Curtiss-Wright / Pentland Systems MPV901P is a single-slot VMEbus analog input/output module engineered for industrial data acquisition and signal processing in demanding environments. This module combines a 32-channel single-ended (or 16-channel differential) analog multiplexer, software-programmable gain amplifier, sample-and-hold circuit, and 12-bit ADC on the input side. The output section provides two 12-bit DACs with associated control logic. Dynamic monitoring of gain settings and channel selection enables real-time settling time calculation, optimizing throughput rates without sacrificing signal integrity.
