FAQ
Q1: What does the “‑P50” suffix in NFDV161‑P50 signify?
A1: The suffix “‑P50” indicates that this module is a version of the NFDV161 series with push‑button edge count capability (P) and general‑purpose non‐explosion version (50).
Q2: How many channels does this module support?
A2: This module supports 64 isolated digital input channels, designed for high–density input applications.
Q3: What input voltage range does it accept?
A3: The rated input voltage is 24 V DC, with ON detection at 20‑26.4 V DC and OFF at 5.0 V DC or less.
Q4: What are the physical dimensions and weight of the module?
A4: The module measures approximately 32.8 mm in width, 107.5 mm in height, 130 mm in depth, and weighs about 0.3 kg.
Q5: What is the minimum input current per channel?
A5: At the rated voltage, the input current is approximately 2.5 mA per channel (±20%).
Q6: What isolation or withstand voltage specifications does it include?
A6: It provides 2 000 V AC between input signal and system for 1 minute, and 500 V AC between commons for 1 minute, ensuring industrial‑grade isolation.
Q7: What kinds of industrial systems is this module appropriate for?
A7: It is suited for large–scale I/O systems in distributed control systems (DCS) or autonomous controllers, where large numbers of field input signals must be collected reliably.
Q8: How long is the typical data refresh or response cycle for this module?
A8: This module features input response times of up to 8 ms or less for status input applications, enabling rapid detection of field ON/OFF transitions.
