PMC Modules PMC408 High Voltage Digital Input/Output The PMC408 monitors or controls on/off (high/low) status for up to 32 devices. Each channel can be used as an input or output. A unique two-piece board design brings the proven reliability of Acromag’s Industry Pack The PMC408 provides an easy method to perform loop-back monitoring of your critical control signals.
