Electrical automation is transforming workplaces across countless industries. These sophisticated, programmable systems generally come in two forms: open- and closed-loop. Each has its advantages and may or may not fulfill your business’s goals. Below is a helpful guide explaining each to ensure you make the most informed decision.

Open-Loop

Open-loop, or non-feedback systems, require a controller—either a human or a piece of computer software—to function. They follow the control order and then stop once it’s achieved. For example, in industrial automation, a conveyor may be programmed to run for 30 minutes. Once the time is up, the conveyor halts, regardless of if there are still items on it.

These systems are technologically simpler, with fewer parts than their closed-loop counterparts, making them easy to maintain. The human factor also means they are more straight-forward to use. This individual can quickly activate the conveyor again or reprogram a timer if an adjustment is needed. However, should that person fail to pay attention, it can disrupt productivity drastically.

Closed-Loop

Closed-loop systems are initially programmed the same as open-loop. The difference is that they receive feedback from their output. In the conveyor example, a closed-loop sensor would detect that the load wasn't fully transferred because there’s still weight on the conveyor. This sensor will then send feedback to the electrical automation controller and activate it to complete the job.

This concept is also used with industrial air conditioners. If the thermostat detects the desired temperature wasn’t reached, it reactivates. This helps maintain a comfortable work environment and reduces the risk of fire.

These complex systems require more parts since they have to read more data input and send error reports. As a result, they need more professional maintenance; repairs are also typically more expensive. However, because they can make adjustments automatically, the final output is usually more accurate; work is also performed more efficiently.
