The Acromag / Xembedded / Xycom XVME-531/2 is a double-high VMEbus analog output module delivering 16 isolated channels of D/A conversion for industrial control and data acquisition. Each channel independently supports voltage or current loop outputs with 12-bit resolution and 500 V optical isolation per channel, eliminating ground loops and reducing noise in demanding environments.
