Here’s a Quick Way to Wire NPN and PNP devices

by

Here’s a Quick Way to Wire NPN and PNP devices I often get asked how to wire NPN and PNP devices to the programmable logic controller. This can be unclear at first when looking at the wiring diagrams. I have managed to destroy a few sensors in the process….. so let’s get started, and I … Read more

How to make a Start Stop Jog circuit in a PLC

by

Looking at a stop-start jog circuit in the PLC will help us understand the differences in hard-wiring the circuit and programming. Basic Start Stop Circuit Let’s start with the primary start-stop circuit. Here is what it looks like hard-wired. (Physical switches wired to outputs devices, such as motor contactors and relays.) When the start pushbutton … Read more

Here is a Method That can Help You with Difficult Level Sensing

by

Turn a capacitive proximity sensor into a level sensor. This is ideal for tanks and vessels you cannot drill through the side for mounting. Wrap the bare wire around the sensing head and extend it to the length you need to detect. Insulate the wire using electrical tape, but leave the end exposed. This acts … Read more

Get Rid Of Surges That Are Destroying Your PLC Outputs

by

DC Solenoids are the worse culprits for electrical surges in your system. When the electrically generated field collapses, an opposite polarity voltage is generated. This voltage spike can be high enough to weld the contacts on a PLC output relay. To protect your PLC output relay, use a diode to ensure that the voltage spike … Read more
