ATF9S-00 | Yokogawa | CENTUM VP Fieldbus Terminal Block

Product Overview

The Yokogawa ATF9S-00 acts as a high-integrity interface for digital fieldbus networks within the CENTUM VP control architecture. This pressure clamp terminal block facilitates the secure termination of up to 16 channels, supporting high-speed data transmission for Foundation Fieldbus and Profibus segments. By utilizing a screwless contact system, the ATF9S-00 ensures signal stability and prevents data dropouts caused by mechanical loosening. We supply this product as 100% Brand New and Original, ready for immediate integration into critical process control networks.

• Humidity Resilience: 5% to 95% RH (Non-condensing).

Engineering Advantages

• Eliminate Signal Jitter in High-Vibration Areas: Fieldbus networks remain highly sensitive to contact resistance fluctuations. The ATF9S-00 employs constant-force spring clamps that maintain a gas-tight seal on the wire. This design effectively solves the problem of intermittent communication errors often found in cabinets located near pumps, compressors, or heavy rotating equipment.

• Accelerate Field Deployment: The tool-free pressure clamp mechanism allows for rapid wiring without the need for torque drivers or specialized crimping tools. This efficiency significantly reduces commissioning timelines for large-scale fieldbus segments where dozens of connections require termination.

• High-Density Marshalling: By supporting 16 channels within a compact footprint, the ATF9S-00 optimizes cabinet space. Engineers can consolidate multiple fieldbus segments into a single terminal area, simplifying cable routing and reducing the overall size of the marshalling enclosure.

• Superior Thermal Stability: The flame-retardant housing and internal conductive elements withstand wide temperature swings from -20°C to +60°C. This ensures that the physical layer of the network remains robust even in non-climate-controlled field enclosures or extreme process environments.

FAQs

• Can I use the ATF9S-00 for standard 4-20 mA analog signals?

  While the mechanical clamps can physically hold the wire, the ATF9S-00 features internal routing optimized for Fieldbus digital signals. For standard analog input/output loops, we recommend using the ATA or ATI series terminal blocks to ensure proper impedance matching and shielding.

• Does this terminal block support redundant Fieldbus segments?

  Yes. When you pair the ATF9S-00 with redundant Fieldbus I/O modules, it provides the necessary physical termination points to maintain dual-path network availability.

• Is any maintenance required for the pressure clamps over time?

  Unlike screw terminals, which require periodic re-torqueing to compensate for wire cold-flow, the ATF9S-00 pressure clamps are maintenance-free. The spring-loaded mechanism automatically compensates for wire settling and thermal expansion.

• Is this product factory-sealed?

  We guarantee the ATF9S-00 is 100% Brand New. Every unit arrives in original Yokogawa factory packaging, complete with authentic serial numbers and quality verification marks.
