Which combination correctly identifies a type of programmable controller?

Which combination correctly identifies a type of programmable controller?

• A. PLR and PAC
• B. PLR only
• C. PAC only
• D. PBC only

Answer: (A)

Programmable controllers come in different forms, including smaller programmable logic relays and more capable programmable automation controllers. A programmable logic relay blends simple relay outputs with programmable logic, making it suitable for straightforward, small-scale control tasks. A programmable automation controller, on the other hand, combines PLC-like control with advanced software and networking capabilities for complex automation applications. Because both PLR and PAC are recognized types of programmable controllers, the combination that includes them is the best fit. The other options limit the scope to a single type or introduce a term not widely recognized as a standard programmable controller, so they aren’t correct in this context.
