This \"slice\" module provides 8 independent 24 VDC sourcing outputs in an ultra-compact form factor. Engineered for high-speed automated machinery, conveyor systems, and process control skids, the ST-3218 drives actuators, solenoids, and indicators with millisecond precision. By integrating into the RSTi network adapter assembly, this module allows engineers to scale I\/O count precisely to the application's needs while minimizing cabinet footprint.
