Yep. DC input, DC output, AC input, AC output. Configurable on a channel-by-channel basis. The Mazak had a LOT of I/O. For example the spindle gearbox had two solenoid valves to control the shift, and two proximity switches to tell the control which gear it was in. Tool clamp/unclamp was one solenoid valve controlling the cylinder that pushes on the drawbar spring stack in the spindle, and two proximity switches to indicate clamped and unclamped. Toolchanger count is something like: forward and reverse valves for the turret, one prox switch to indicate that a turret slot is aligned with the changer, five prox switches (binary encoded) to tell which slot. Two valves and two prox switches for the transfer arm, three to five valves for the main toolchanger arm (extend, retract, and two different rotation angles), a similar number of prox switches for that arm. Contactors for coolant, lube, and hydraulic pumps. Pressure switches for lube oil and hydraulic. And many more that I don't remember, including some that we never even figured out what they do.
