Yokogawa ATI3S-00 CENTUM VP Pressure Clamp Terminal Block

Product Overview

The Yokogawa ATI3S-00 functions as a high-integrity interface for isolated analog and pulse modules within the CENTUM VP Distributed Control System (DCS). It provides the physical termination point for critical field signals, ensuring seamless data flow between instrumentation and the control environment. We supply this unit in 100% Brand New and Original condition, specifically designed to eliminate connection-related signal drift in high-precision control loops.

Technical Specifications

The ATI3S-00 utilizes robust mechanical and electrical parameters to maintain signal purity:

• Termination Type: Pressure Clamp (Screwless spring-tension design)

• Rated Voltage: 24 V DC

• Rated Current: 0.5 A per channel

• Dielectric Strength: 1500 V AC for 1 minute (Ensures high-voltage surge protection between system and field)

• Insulation Resistance: 100 MΩ at 500 V DC

• Dimensions: 120 mm (L) x 80 mm (W) x 40 mm (H)

• Weight: 0.2 kg

• Surge Absorber: None (Basic configuration for streamlined signal paths)

Engineering Advantages

• Vibration-Proof Signal Integrity: The ATI3S-00 features a specialized pressure clamp mechanism. Unlike traditional screw terminals that loosen under mechanical stress, this spring-loaded design maintains constant contact pressure. This solves the industrial challenge of "flickering" signals in environments near high-vibration machinery like pumps or compressors.

• Streamlined High-Density Installation: The compact 120mm x 80mm footprint allows engineers to maximize cabinet space. Its lightweight 0.2 kg profile reduces the mechanical load on DIN rails, enabling denser marshalling configurations without compromising structural safety.

• Rapid Wiring Efficiency: The screwless design accelerates commissioning timelines. Technicians insert wires directly into the clamp, removing the need for torque-specific tightening. This minimizes human error and reduces the risk of stripping threads during field installation.

• Enhanced Safety and Isolation: With a dielectric strength of 1500 V AC, this terminal block provides a robust barrier against electrical noise and cross-channel interference. It protects sensitive isolated modules from external electrical faults, ensuring the longevity of your DCS hardware.

FAQs

• Can I use the ATI3S-00 with 16-channel modules?

  No. The ATI3S-00 specifically supports 8-channel architectures. For 16-channel applications (such as AAI143), you must select a high-density terminal block like the ATA4D.

• Does this model include surge protection?

  The ATI3S-00 is the basic version without integrated surge absorbers. If your installation site is prone to lightning strikes or heavy inductive switching, we recommend installing external surge protection or selecting a variant with built-in absorbers.

• Is this a refurbished or used component?

  Absolutely not. We guarantee this product is 100% Brand New. Each unit ships in original Yokogawa factory packaging, complete with the original serial number and quality assurance labels intact.

• Does the unit support hot-swapping?

  While the terminal block itself is a passive mechanical component, it supports the hot-swapping of the associated I/O modules. The pressure clamps ensure that field wiring remains secure and undisturbed during module replacement.
