FAQs (10 Questions & Answers)

Q1: What does the “P50” suffix mean in ADV151‑P50?

A1: The “P” indicates a module with pushbutton input functionality. The “5” means it is a basic type without status display or explosion‑proof features. The “0” denotes the base version of that variant.

Q2: How many input channels does ADV151‑P50 support?

A2: It supports 32 input channels.

Q3: What voltage is required for signals to be considered “ON”?

A3: Input ON is recognized when the voltage is in the range 18.0 to 26.4 V DC.

Q4: What is the OFF threshold?

A4: Input OFF is any voltage 5.0 V DC or less.

Q5: What is the response time for status inputs?

A5: Status inputs respond in 8 ms or less.

Q6: Can ADV151‑P50 detect button presses (pushbutton)?

A6: Yes. It supports pushbutton input detection; the minimum ON detection time is about 20 ms, maximum ON/OFF cycle for pushbutton input is 25 Hz.
