Everyone- I'm looking for a simple PLC/motor controller for a project. Cost should be at or below $1000US, in single-unit to tens/year quantity. Should be programmable, have approximately 20 user I/O lines capable of driving a 24V relay coil. I/O should be optically isolated. Motor drive should be stepper motor based. Open loop is acceptable. Torque/power need not be ridiculously high. Should be capable of serial communication for low-speed polling based synchronisation with a PC. Anyone have any suggestions?
