It receives contact ON\/OFF signals, voltage pulses and current pulses from field transmitters. Each input channel is isolated from the system and from the other channels, allowing pulse signals from different field devices to be acquired independently.\u003c\/p\u003e\n\u003ch3\u003ePulse Input Function\u003c\/h3\u003e\n\u003cp\u003eThe NFAP135 supports five input modes to accommodate different pulse transmitter configurations:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDry contact pulse using an open-collector contact.\u003c\/li\u003e\n\u003cli\u003eDry contact pulse using a relay contact.\u003c\/li\u003e\n\u003cli\u003eVoltage pulse input.\u003c\/li\u003e\n\u003cli\u003e2-wire transmitter current pulse input (4-20 mA).\u003c\/li\u003e\n\u003cli\u003e3-wire transmitter voltage pulse input.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor current pulse input, the incoming current signal is converted to voltage within the input circuit.

Its maximum current consumption is specified separately for the 5 V DC and 24 V DC supply rails.\u003c\/p\u003e\n\u003cp\u003eThe transmitter power supply selection is independent of the module's system power consumption specification. The 12 V DC or 24 V DC setting must be selected according to the connected transmitter and the required input mode.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the NFAP135-S01 accept both contact pulses and 4-20 mA pulse signals?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The NFAP135 supports dry contact pulses, voltage pulses and 2-wire current pulse signals. For 4-20 mA current pulse input, the appropriate shunt resistance and INA-INB connection must be selected.\u003c\/p\u003e\n\u003cp\u003eQ: Can all eight channels operate at 10 kHz?\u003c\/p\u003e\n\u003cp\u003eA: The general input frequency specification is 0 to 10 kHz. However, the open-collector dry contact input mode is limited to 800 Hz. The minimum input pulse width is 40 us, so the transmitter signal must also satisfy this requirement.\u003c\/p\u003e\n\u003cp\u003eQ: What should be checked when using a 500 ohm shunt resistance?\u003c\/p\u003e\n\u003cp\u003eA: The 500 ohm setting has specific installation restrictions. No module may be installed adjacent to the NFAP135, and the pulse input module must be used with no more than four inputs.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":68890499481842,"sku":"NFAP135-S01","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/NFAI543-S511.jpg?v=1793930929","url":"https:\/\/www.petrospare.com\/products\/yokogawa-nfap135-s01-pulse-input-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
