What is a typical payback period?

It varies widely with shifts, labor costs and utilization. Projects running multiple shifts usually pay back faster than single-shift cells.

PNP or NPN?

It depends on your PLC inputs. PNP (sourcing) is common in Europe and North America; NPN (sinking) is common in parts of Asia. Match the input card.

Do cobots need guarding?

Sometimes. A cobot application is only collaborative if the risk assessment shows it is safe, including the tool and the part. Sharp or heavy payloads may still need guarding or scanners.

What is the difference between a micro PLC and a modular PLC?

Micro PLCs have fixed or limited I/O for small machines. Modular PLCs add I/O, communication and specialty modules for larger systems.

Why trust AutomationReviewed

Task, payload and safety first

How we test
01Datasheet first

Every comparison uses the published datasheet figures for payload, reach, repeatability and ratings, with the source linked.

02A clear verdict

Each guide says who the equipment suits, who should look elsewhere, and what to check before you buy.

03No paid placements

Brands cannot buy a review or a spot on a list. Partner codes save you money; they never decide what we recommend.

04Kept current

Prices are dated, codes are updated across the site at once, and pages are revised when a product, standard or rule changes.
