The PLC outputs will be attached to a bank of relays, which will close an internal contact, allowing electricity to be sent out to toggle on or off a device on the manufacturing line. Contactors are used to drive motors, whereas relays control devices such as lights and fans.
Since many hydraulic control panels are used on active (often outdoor) job sites, these control boxes often have to be built a little tougher than others. You might need an enclosure that’s weatherproof, corrosion-resistant, impact-resistant or all of the above. Sensor lights for troubleshooting are also especially useful in hydraulic control boxes, helping users to pinpoint a system error in these often-complex networks of valves, cylinders and hoses.
Never forget that the circuit breaker's top always has electricity. The input voltage to the panel can range from 480 volts down to 120 volts or less.
