FAQ
FAQ
Q1: What types of signals can the NFAP135 receive?
A1: It supports contact ON/OFF, voltage pulse, and current pulse inputs from 2-wire or 3-wire transmitters.
Q2: What is the maximum input frequency supported?
A2: The module supports up to 10 kHz, but for dry contact inputs the limit is lower, such as 800 Hz or below depending on wiring capacitance.
Q3: Is input signal isolation provided between channels?
A3: Yes, the module provides isolation between each input channel and between input and system.
Q4: Can the module supply power to transmitters?
A4: Yes, selectable 12 V DC or 24 V DC power is available with current limits of 40 mA and 30 mA respectively.
Q5: Is there support for filtering contact bounce (chatter)?
A5: Yes, a noise elimination filter can be enabled for mechanical contacts at frequencies up to 10 Hz.
Q6: What is the minimum detectable pulse width?
A6: The minimum pulse width is 40 μs, though for dry contacts this increases with load capacitance.
Q7: Are shunt resistors configurable?
A7: Yes, options include OFF, 200 Ω, 500 Ω, and 1000 Ω depending on the input mode.
Q8: What are the installation dimensions and weight?
A8: The module measures 32.8 × 107.5 × 130 mm and weighs approximately 0.3 kg.
