ATI3S-001 Yokogawa Pressure Clamp Terminal Block

The Yokogawa ATI3S-001, also cataloged as the ATI3S Pressure Clamp Terminal Block, operates as a dedicated hardware component for field signal termination and cable interface connection within Yokogawa CENTUM VP and ProSafe-RS platforms.

Hardware Specifications

Yokogawa Thermal Junction Compensation & Channel Isolation Interface

The terminal block assembly routes field instrument conductors directly into underlying I/O module backplane buses. Integrated internal barrier isolation suppresses noise coupling into 4-20 mA HART loop protocol pairs and millivolt sensor circuits. For thermocouple inputs, the physical construction supports cold junction compensation (CJC) temperature tracking across terminal points while maintaining channel-to-channel isolation boundaries.

Frequently Asked Questions

Q: Does the ATI3S-001 require periodic mechanical torque maintenance on field connections?

A: No, the pressure-clamp mechanism maintains constant tension on field conductors, eliminating screw loosening caused by ambient thermal cycling and mechanical vibration.

Q: Can the ATI3S-001 terminal block be disconnected without removing individual field wires?

A: Yes, the terminal block assembly unlatches directly from the baseplate connector interface, allowing field wiring harnesses to remain intact during module swapping.

Field Installation Guidelines

Mount the ATI3S-001 pressure clamp terminal block onto the baseplate interface slot until the retention latches engage firmly. Strip field wire leads to specified strip lengths, depress the clamp lever with a terminal tool, insert the conductor, and release to secure the connection. Route field cables through panel wire ducts separated from high-voltage AC mains lines, and terminate all overall cable shields directly to the cabinet earth grounding bar.
