DC2-STN stand-alone, two-axis servo controller has two auxiliary outputs for stepper control. This 9.5 X 4 X 5-inch unit has back-panel-mounting tabs and removable/pluggable screw terminals for easy wiring. The controller features a RS232 communication interface for programming and networking; 32K non-volatile memory to store macros, programs, and point information; opto-isolated I/O at industrial voltage levels; status LEDs; and a watchdog relay output for external monitoring. The DC2-STN's multi-tasking capability permits as many as four independent tasks or routines to run simul-taneously without interrupting motion control.
