Programmable Logic Controllers (PLCs) are extremely common in a large number of industrial control systems. This includes railroad passenger cars, where they have been used for everything from destination sign controls to HVAC controls to data aquisition and management. To date, Northwest Rail Electric has constructed a number of systems incorporating PLCs. All of these have been constructed to the specifications of the customer to suit various needs. This flexibility and versatility is likely to make PLC based control systems continue to increase in popularity. These are a few examples of PLC based control systems that we have produced for various railroad passenger car applications.



Northwest Rail Electric NW-DD-DAQ-PLC records an extensive array of operating data on one of our customer's passenger cars, and reports it to the car shop computer system by wireless network when the car returns to the shop.
