A simple example of an interlock is pushing the brake pedal or clutch in your car before shifting it into drive or first gear. You need to press on the brake pedal to release the shifter into the drive position to prevent the car from lurching forward. There are two main types of interlocks: safe and non-safe. Some systems require safe and non-safe interlocks to create a control system. These interlocks prevent people or things from receiving harm while the machine is running. For example, a safety fence on a robotic cell keeps people out of the cell to protect them from contact with moving objects. When the fence gate of the cell is opened the safety circuit cannot be reset because the circuit is waiting for the gate to be closed. This prevents a person from walking into a robot cell while the robot is running. The other main type of interlock is a non-safe interlock. These are used to protect equipment or unintended operations. There are three different kinds of non-safe interlocks. These types of interlocks can be mechanical, electrical, or logic interlocks. A mechanical interlock is an interlock that is physically connected to another device to prevent unintended actions. An electrical interlock is an interlock that is used to restrict current flow between two or more devices. These types of interlocks use normally open and normally closed contacts to prevent another device from turning on. A logical interlock has an instruction or variable which has to be true to allow a result. Logical interlocks are useful when the devices are not easily connected electrically or mechanically. ============================= Order a Siemens PLC Starter Kit: bit.ly/30aCoyP Get a RealPars pro membership: learn.realpars.com/bundles/pro ============================= You might want to review two of our other articles: What is a Safety PLC? realpars.com/safety-plc Motor Starter Explained | Motor Starter Types realpars.com/motor-starter ============================= Missed our most recent videos?
