Configured for high-integrity field interfacing in Yokogawa control platforms, the Yokogawa NFTP5S-00 (NFTP5S Pressure Clamp Terminal Block) provides direct physical/electrical execution for process signal termination. This component functions as the primary mechanical and electrical conduit between field-side instrumentation and the I/O subsystem, ensuring signal path stability in demanding environmental conditions.

Suffix Breakdown & Model Matrix

• NFTP5S: Base model designation for the high-density pressure clamp terminal block.
• -00: Standard configuration identifier for general-purpose industrial applications.

Hardware Specifications

Process Interface & Connectivity

The NFTP5S-00 is engineered to maintain high-fidelity signal transmission while providing superior resistance to environmental degradation. The pressure clamp architecture ensures a gas-tight electrical bond, preventing oxidation or loosening of conductors due to industrial vibration. With a stability rating of +/- 0.1 % of span per annum, the terminal block serves as a stable interface for sensitive analog loops and digital inputs, minimizing drift in process measurements over long-term operation. The unit is optimized for fast signal response (<= 250 ms), ensuring that the termination hardware does not introduce latency into the control loop.

Frequently Asked Questions

Q: Does the NFTP5S-00 introduce significant latency to the control loop?

A: No. With a rated response time of <= 250 ms (for 90 % of the signal), the terminal block is optimized for rapid signal throughput, ensuring it does not become a bottleneck in standard industrial control applications.

Q: Is the terminal block suitable for extreme temperature variations?

A: Yes. The unit is rated for an operating range of -40 deg C to 85 deg C and storage up to 100 deg C, making it suitable for deployment in harsh climate-controlled or non-controlled industrial environments.

Field Installation Guidelines

• Mounting: Secure the NFTP5S-00 to the system cabinet backplane or DIN rail. Ensure that the module interface is aligned to prevent bent pins or connector misalignment.
• Wiring: Strip the insulation from conductors to the length required for the pressure clamp. Ensure the wire gauge is compatible with the clamp specifications to ensure the rated load capacity (Max 600 Ohm).
• Grounding: Where signal shielding is required, terminate the cable drain wire to the dedicated ground bus within the cabinet to maintain the specified noise immunity and stability.
• Commissioning: Post-installation, verify the resistance of the loop at the terminal block to confirm the connection is within the 600 Ohm limit and ensure that the process signal matches the controller input value.
