The PC78 is a PC/104 bus-based controller, and Stand-Alone controller, with high speed RS232 port, will operate from up to 4 axes of Stepper, and Servo applications. Independent and coordinated motion of all axes. The PC78 supports up to 24 general purpose TTL I/O. The step pulse is a TTL level 50% duty cycle square wave that supports velocities of 0 through 1,044,000 pulses per second. The encoder feedback functionality supports quadrature encoders up to 12 MHz and is used as feedback for the servo or stepper axes or as independent position feedback. Every axis includes dedicated opto isolated +/- over travel inputs, a home input, and an auxiliary output. The PC78 is available in several different models at several different prices so that you dont have to pay for a lot of functionality that you dont need.
