Yokogawa ATI3S-S00 Pressure Clamp Terminal Block

The Yokogawa ATI3S-S00, 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 I/O node units.

Suffix Breakdown & Model Matrix

• ATI3S: Base model designating pressure clamp terminal block assembly for signal termination.
• -S: Standard signal connection structure suffix.
• 00: Basic non-option hardware specification variant.

Hardware Specifications

Yokogawa Signal Termination & Loop Protection

The pressure clamp terminal block directly terminates field instrument conductors and routes signals to the corresponding I/O interface module. Integrated terminal insulation maintains channel-to-channel isolation and guards against signal degradation in 4-20 mA HART loop protocol pairs and discrete control lines. The spring-loaded clamp mechanism ensures constant mechanical force on wire leads, preventing intermittent connection loss caused by thermal expansion or enclosure vibration.

Frequently Asked Questions

Q: Does the ATI3S-S00 terminal block require tool-assisted torque checks during routine maintenance?

A: No, the pressure clamp design uses spring-tensioned retention, eliminating the need for periodic screw retightening while maintaining constant electrical contact force.

Q: Can the ATI3S-S00 terminal block be removed without disconnecting individual field conductors?

A: Yes, the terminal assembly unlatches directly from the module baseplate, allowing field wiring to remain fully wired during I/O module replacement.

Field Installation Guidelines

Mount the ATI3S-S00 pressure clamp terminal block onto its corresponding I/O module slot until the locking levers engage fully with the baseplate assembly. Strip field wire insulation to the manufacturer-specified strip length, depress the clamp spring lever with a standard screwdriver, insert the conductor, and release the lever to lock the wire in place. Ensure all cable shields are bonded to the designated cabinet earth grounding bar and maintain physical separation from high-voltage AC lines within the wire duct.
