uct Introduction
The Yokogawa NFTP5S-00 Pressure Clamp Terminal Block for Digital is a precision-engineered terminal interface module designed to ensure secure, stable, and noise-resistant electrical connections within digital instrumentation and control systems. It is part of Yokogawa’s field wiring and I/O interconnection line, serving as a robust interface between the digital I/O modules and external field wiring.
This terminal block uses a pressure clamp connection system, allowing wire fastening without the need for soldering or screw tightening. The clamping mechanism ensures consistent contact pressure over time, even in environments subject to vibration, temperature fluctuation, and electrical noise. The design eliminates connection loosening and minimizes maintenance frequency, supporting Yokogawa’s long-term operational philosophy for reliable industrial automation.
The NFTP5S-00 is built with high-grade insulating materials and precision metal contacts to maintain signal integrity for digital control signals such as ON/OFF status, pulse inputs, and logic outputs. Its compact, modular form makes it ideal for mounting in Field Control Units (FCUs), control cabinets, and distributed I/O systems.

FAQ
-
What connection method is used in the NFTP5S-00?
It uses a spring-loaded pressure clamp mechanism that secures conductors through contact pressure rather than screws. -
Can this terminal block handle both input and output digital signals?
Yes, the NFTP5S-00 supports both digital input and output signal channels within the same module. -
What wire size range is supported by the clamp mechanism?
It typically supports solid or stranded conductors from 0.25 mm² to 1.5 mm² (AWG 24–16). -
Is it compatible with Yokogawa digital I/O modules?
Yes, it is designed to match the connector layout and electrical characteristics of Yokogawa’s digital I/O series. -
How is wire release performed during maintenance?
A small flat tool or push lever is used to open the clamp, allowing quick removal or reinsertion of conductors. -
Does the terminal block include isolation between channels?
Each terminal is individually insulated to prevent cross-channel interference or short circuits. -
Can it be mounted on a DIN rail?
Yes, it supports DIN-rail mounting as well as direct chassis installation. -
What is the maximum switching voltage for digital signals?
The NFTP5S-00 supports up to 30 V DC or 250 V AC, depending on the connected circuit. -
How does the design minimize noise and interference?
Low contact resistance, short internal paths, and shielded housing reduce electrical noise pickup. -
Is this terminal block suitable for high-vibration or mobile equipment?
Yes, its pressure clamp mechanism ensures stable contact even under vibration, making it ideal for mobile or rotating machinery control panels.
