Product Description

The Yokogawa ATA4S-10 S2 is a vibration-resistant pressure clamp terminal block, designed to ensure secure and reliable electrical connections for field instrumentation and control signal wiring. Specifically engineered for Yokogawa’s DCS and PLC architectures, this terminal block simplifies multi-core cable termination while maintaining high electrical integrity. The pressure clamp mechanism eliminates the need for specialized crimp lugs, reducing installation time and providing a gas-tight contact that resists oxidation and loosening in high-vibration industrial environments.

Technical Specifications

Operational Reliability and Maintenance

The ATA4S-10 S2 ensures high-precision signal transmission, minimizing voltage drop and contact resistance. Its pressure clamp design guarantees consistent contact pressure, even during temperature-induced expansion or thermal cycling. Ideal for pressure, temperature, and flow transmitters, this unit supports high-density mounting, allowing engineers to maximize control panel space while ensuring organized, accessible wiring for troubleshooting.

Frequently Asked Questions

What is the primary advantage of the "Pressure Clamp" design?
The pressure clamp mechanism provides consistent, uniform force on the conductor, creating a reliable, gas-tight connection that resists loosening from mechanical vibration—far superior to traditional screw-terminal blocks.

Is the ATA4S-10 S2 compatible with existing wiring?
Yes, the terminal block is compatible with standard instrumentation wire gauges used in Yokogawa DCS installations, allowing easy replacement or expansion.

Can I replace an old screw-type terminal block with this model?
Yes, typically. Ensure the physical mounting profile and wiring harness match. However, it's recommended to verify the connection pinout against your specific module's wiring diagram for full compatibility.
