This is our industrial control panel trainer with an Allen Bradley Micro 820 PLC and analog I/O module. It includes 12 discrete 24VDC inputs, 8 discrete 24VDC outputs, 2 analog inputs, and 2 analog outputs. Designed for both schools and individuals who wish to learn more than the basic trainers and instruction manuals can't teach.
They include four momentary push buttons, two 2 position selector switches, two 3 position selector switches, four lights, a 0-10K ohm potentiometer, a 4-20mA analog gauge, an open style 2 pole double throw normally open/normally closed contactor that you can see the physical contacts of, a three phase drive, a three phase motor, and a heater mounted in front of the fan for teaching process control such as PID.
The trainer requires 120VAC and plugs into your typical wall outlet. The drive outputs 230 VAC to the three phase fan drive which is pre-wired on the trainer.
All other wiring on the trainer is designed to be 24VDC including the heater. These trainers are not pre-wired. Students are expected to wire the trainers to make them function by following the lessons at the following link which gives them valuable insight into how industrial control panels are wired and operate. There are lessons available to wire PLCs into them. https://www.theautomationstore.com/lessons/
These trainers are built to order and typically take 1 to 2 weeks to ship.

1. Push Button - Your trainer comes with four push buttons. A green, yellow, and blue momentary push button and a red maintained mushroom button (note image does not show mushroom button). Each button has two normally open (NO) contacts and two normally closed (NC) contacts. The normally open contacts are color coded green and the normally closed contacts are color coded red on the back of the trainer.
2. Selector Switch 2 Position - Your trainer has two 2 position selector switches. There is a normally open contact on each selector switch that closes when you turn the switch to the right (clockwise).
3. Selector Switch 3 Position - Your trainer has two 3 position selector switches. There is a normally open contact for both the left and right position of the selector switch.
4. Lights - Your trainer has four lights colored green, yellow, red, and blue.
5. Analog Potentiometer and Gauge - Your trainer has a 10K potentiometer and a 4-20mA analog gauge.
6. Contactor Relay - Your trainer has one contactor/relay which is an open style so you can see how it works. It is a double pole double throw which means it has two sets of contacts with both normally open and normally closed positions.
7. AC Drive - Your trainer has a AC inverter drive which takes 120VAC in and creates 240VAC 3 phase out so this trainer can be used to learn about 3 phase power yet plugs into a standard wall outlet.
8. 24VDC Power Supply - Your trainer comes with a 24VDC 50 watt switching power supply. The trainer is designed for all switches, lights, relay/contactor, and even the heater to be powered by 24VDC making it much safer than 120VAC trainers.
9. 3 Phase Motor/Fan - Your trainer comes with a 3 phase fan. It along with the item 7 AC drive allows for 3 phase principles to be taught when only 120VAC wall outlet power is available.
10. Heater and Thermocouple - Your trainer includes a 24VDC heater and type J thermocouple. The item 6 relay/contactor can be used to switch the heater on and off. WARNING! If your trainer came with one of our optional PLCs do not connect this heater directly to one of the PLCs outputs as its current draw is greater than the current rating of most PLC outputs. Connect the heater to the item 6 relay/contactor and connect your PLC output to the relay contactors coil. There are instructions on doing this in later lessons.
11. Thermocouple to 4-20mA converter - No longer included on this model
12. Terminal blocks - To make your trainer more realistic, we have included terminal blocks for connecting to the 24VDC power supply and the heater. You may add more as you customize your trainer.
13. PLC - We have several optional PLCs or you may add your own so the PLC provided is not shown in this image. There are lessons on wiring other components to your PLC and programming it. Lessons are written for Allen Bradley but can easily be followed for use with other PLCs such as Automation Direct, Mitsubishi, Omron, Siemens, etc.
