Overview
The Crydom 6201A is a surplus AC input solid-state relay module from the IAC5 series designed for PLC processors and industrial automation systems. This module accepts AC voltage inputs ranging from 90–140VAC and provides isolated 5VDC logic output, making it ideal for interfacing high-voltage AC signals with digital control circuits. The module is now obsolete but remains a reliable choice for legacy system maintenance and repairs.
