A PLR is a solid-state control device that contains ___.

• A. timers
• B. relays
• C. counters
• D. all of these

Answer: (D)

A PLR, or Programmable Logic Relay, is a compact solid‑state control device that combines multiple control functions in one unit. It can perform timing functions (timers) to create delays or timed sequences, counters to count events or items, and it provides switching outputs (relays) to drive loads. Because a PLR integrates these capabilities, it can handle sequencing, timing, and load switching without needing separate devices. That’s why all of these features are included in a PLR, making the option that includes timers, counters, and relays the best choice.
