The Allen-Bradley 4100-212-RA controller is an IMC S Class standalone integrated motion controller. Also known as a servo motor controller, the 4100-212-RA standalone integrated motion controller is a 2-axis motion controller that has a 16 bits resolution and a 90 to 130 Volts AC or 175 to 260 Volts AC input voltage rating. The 4100-212-RA standalone integrated motion controller also has an I/O power input voltage that ranges from 5 to 40 Volts DC and it features an analog input option. Also found on the 4100-212-RA IMC S Class controller are 10 dedicated discrete inputs, a memory lock key, a serial port for standard communications modules, and remote I/O communication modules.

Note that the entire 4100-212-RA IMC S Class controller measures approximately 20 x 11 x 8 inches or 508 x 279.4 x 203.2 millimeters and that it has a weight of about 22 pounds or 9.98 kilograms. The Allen-Bradley 4100-212-RA IMC S Class standalone integrated motion controller is obsolete, but still available second hand for mechanical systems that are engineered to accommodate it. The 4100-212-RA controller is designed to control the servo motors of bigger machines or machine systems in factories or other industrial settings.
