Do I have to replace the entire PCB due to a single relay failure… What? Can I just replace one relay!?

Design / Development / Purchasing Maintenance
No need to replace the entire PCB anymore. Replacing individual components reduces costs and work time.

Various industrial devices are required not only to operate stably for long periods of time, but also to minimize downtime. When a problem occurs or equipment stops operating, it is important to be able to recover as quickly as possible, and reducing maintenance time is a major challenge. Therefore, we had no choice but to replace the entire PCB. OMRON contributes to both cost reduction and shortening of work time by providing products that allow for easy replacement of individual components.

Even if the problem is with a single component, replacing the entire unit incurs significant costs.

PCB-mounted component

Replacing the entire PCB due to a single relay failure

Replacing individual components (removing the solder and soldering the new component) often results in inconsistent quality. Therefore, in most cases, the entire PCB is replaced.

Considering quality, individual components cannot be replaced… It’s costly but there is no other way…

Wiring harness assembly

Replacing the entire harness assembly solely due to a single wire breakage

It is necessary to cut off the cable and connect a new connector (replace the entire connector), which results in waste loss of the component and shortened machining dimensions.

Do I really have to replace the connector just because the wire is broken?

OMRON contributes to reducing maintenance costs and shortening work time by providing components that can be replaced individually even after being mounted.
