FAQ (Frequently Asked Questions)

Q1: How many input channels does the ADV151‑P13 S2 module provide?
A1: It provides 32 discrete digital input channels in a single module.

Q2: What input voltage is required for each channel?
A2: The module is designed for 24 V DC input. The turn‑ON voltage is between 18.0 and 26.4 V DC, and OFF is ≤ 5.0 V DC.

Q3: What is the response time to input signal changes?
A3: The response time for standard (status) inputs is 8 ms or less.

Q4: Can the module detect push‑button inputs or momentary contacts?
A4: Yes, the channel supports a minimum ON detection time of ~20 ms and a maximum ON/OFF cycle of about 25 Hz (in push‑button mode).

Q5: What are the dimensions and weight of the module?
A5: Approximate dimensions: 110 mm × 30 mm × 130 mm. Approximate weight: 0.20 kg.

Q6: What kind of isolation does the module provide between input and system?
A6: It provides high isolation: 2 kV AC between input signal and system, and 500 V AC between commons (every 16 channels) and system, for one minute.

Q7: Is the module suitable for redundant I/O systems?
A7: Yes. It is designed to fit into field I/O racks and supports architectures that include redundant I/O modules, ensuring increased system availability.

Q8: In which environments can this module be used?
A8: The module is suitable for industrial automation, manufacturing, process plants, power / utility, oil & gas, water/wastewater – wherever many discrete input points and high reliability are required.

Q9: What makes this module advantageous for retrofit or expansion projects?
A9: Its high channel count, compact footprint, standard 24 V DC input interface, and compatibility with field I/O ecosystems make it well suited for expansion or retrofit of existing control systems.

Q10: If I require higher channel density or special capabilities like SOE logging, what should I look at?
A10: For higher channel density you might consider modules like the ADV161 series (64‑channel), or for special capabilities such as Sequence‑of‑Events (SOE) logging you might choose other variants within the ADV151 family that support that feature.
