Features:

  • Eight isolated channels for pulse counting.
  • Wide pulse input frequency range from 0 to 10 kHz.
  • Flexible NFTI3S terminal block or 40-pin MIL connection.
Accurate pulse counting supports flow measurement, production monitoring, equipment speed detection, and event accumulation in industrial automation systems. Yokogawa NFAP135-S00 S2 receives pulse signals through eight independently isolated channels. Each channel can count signals within a frequency range of 0 to 10 kHz. Isolation helps reduce interaction between connected input circuits. The module provides a practical interface between pulse-generating field equipment and an FCN I/O system.

Connection options allow the module to suit different control cabinet and wiring arrangements. Yokogawa NFAP135-S00 S2 supports the NFTI3S pressure clamp terminal block for organized field termination. A 40-pin MIL connector is also specified for compatible cable assemblies. NFTI3S can also support NFAI135 and NFAI835 module configurations. Conduit wiring must be applied when NFAP135 uses a cable connection in power supply mode.

Power capacity must be evaluated during system configuration to maintain reliable I/O operation. Yokogawa NFAP135-S00 S2 must be installed without exceeding the rated output of the associated power supply module. Both 5 V DC and 24 V DC consumption must be considered when selecting the module combination. Hazardous-area approvals provide options for applications requiring FM, CSA, ATEX, or UKEX protection. Proper wiring, power calculation, and approval selection help integrate the module into demanding industrial environments.

The NFAP135-S00 S2 Yokogawa Pulse Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Pulse signals from compatible field devices can be collected by Yokogawa NFAP135-S00 S2 through eight isolated input channels. The module performs pulse counting across an input frequency range of 0 to 10 kHz. Channel isolation separates individual input circuits, supporting stable signal acquisition in industrial control and monitoring applications.

Field wiring for Yokogawa NFAP135-S00 S2 can be completed through an NFTI3S pressure clamp terminal block or a 40-pin MIL connector. NFTI3S supports eight-channel connections for NFAP135 and NFAI135, along with four input and four output channels for NFAI835. Conduit wiring is required for the cable connected to NFAP135 when the module operates in power supply mode.

Installation planning for Yokogawa NFAP135-S00 S2 must account for the rated output capacity of the power supply module. Combined I/O module consumption must remain within the available 5 V DC and 24 V DC power limits. Only one module among NFAI141, NFAI841, NFAB841, NFAI835, and NFAP135 can be installed under the stated limitation involving both power supplies. Hazardous-area protection options include US FM non-incendive, Canada CSA non-incendive, ATEX Ex ec, and UKEX Ex ec approvals.
