This is the forth in our series of "miniature machine" PLC Trainers, these are real functioning machines and will work just like a production machine. PLC is not included. This will also connect to ANY 24 volt input and relay or 24 volt PLC trainer or a standalone PLC with 1 analog 0-10v input and 1 analog 0-10v analog output, we will customize any of our trainers to be compatible with all of our mini machines. The scope for this trainer to levitate the ball at a given height and the PID will keep the ball at the correct height, the variables are fan speed, manual damper at the top of the tube and at the bottom a electrical damper controlled via the PLC or push buttons. If the PID is set up correctly it should be able to compensate for the damper position and the more or less airflow and keep the ball at the given height. What is has: 1 fan assembly that pushes the ball to the top of the tube 1 0-10VDC analog proximity switch on the top of the tube to give the PLC feedback of actual position of the ball 1 0-10VDC meter in showing the signal coming from the PLC to control fan speed 1 0-10VDC meter out going to the PLC as a feedback for position of the ball 1 manual potentiometer for fan speed control, this will be the initial setting then and the input will be the span 1 damper at the bottom of the tube 1 manual open damper switch 1 manual close damper switch 1 manual damper at the top of the tube We can supply our optional PLC, this one is being controlled by an MicroLogix 1400, you can use any brand of PLC’s with our ‘miniature machine series’, if you have your own you can supply the PLC, just make sure the inputs are 24VDC and the outputs are either DC or relay and has one 0-10v analog in and one 0-10v analog out.
