This module features eight (8) isolated current output channels, providing double the channel density of standard SLC 500 output modules while occupying only a single slot in the chassis. It is specifically designed for high-precision control of modulating field devices, including variable frequency drives (VFDs), control valves, and actuators, as well as for signal retransmission to data acquisition systems.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEight (8) independent current output channels.\u003c\/li\u003e\n\u003cli\u003eHigh-resolution 16-bit digital-to-analog conversion for precise process control.\u003c\/li\u003e\n\u003cli\u003eSingle-slot footprint for efficient chassis space utilization.\u003c\/li\u003e\n\u003cli\u003eSupports standard industrial output ranges of 0–20 mA and 4–20 mA.\u003c\/li\u003e\n\u003cli\u003eCompatible with standard SLC 500 backplane power requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is ideal for industrial automation environments requiring high-density analog control, such as chemical processing, water treatment, and manufacturing assembly lines.
