Configured for field-level signal termination in CENTUM VP distributed control systems, the Yokogawa ATC5S-00 (ATC5S Pressure Clamp Terminal Block) provides direct physical/electrical execution for I/O module wiring. This component serves as the primary mechanical interface between external field devices and the internal FIO (Field I/O) subsystem, ensuring secure signal path integrity and stable electrical contact.

Suffix Breakdown & Model Matrix

• ATC5S: Base model designation for the CENTUM VP pressure clamp terminal block interface.
• -00: Standard configuration identifier for general-purpose industrial applications.

Hardware Specifications

Process Interface & Connectivity

The ATC5S-00 is engineered to facilitate reliable signal transmission by utilizing pressure clamp technology, which ensures a gas-tight electrical connection that resists loosening under mechanical vibration. By functioning as a passive bridge between field wiring and the system I/O module, the terminal block maintains signal consistency for both analog and digital loops. Its compact form factor is specifically optimized for high-density rack configurations within CENTUM VP cabinets, allowing for organized wire management while maintaining accessible points for diagnostic testing.

Frequently Asked Questions

Q: Does the ATC5S-00 require specific wiring tools for installation?

A: The pressure clamp design is generally tool-operated; a flat-blade screwdriver is typically utilized to actuate the spring mechanism, allowing for the insertion of standard copper conductors without the need for specialized crimping.

Q: Is this terminal block compatible with high-vibration environments?

A: Yes. The spring-loaded pressure clamp provides constant contact pressure on the wire, which is superior to standard screw-type terminals in preventing wire backing-out due to industrial vibration.

Field Installation Guidelines

• Mounting: Install the ATC5S-00 by securely latching it onto the designated terminal baseplate or rail within the CENTUM VP cabinet. Ensure correct alignment with the corresponding I/O module port.
• Wiring: Strip wires to the recommended length as specified in the CENTUM hardware manual. Ensure the conductor is fully inserted into the terminal before releasing the spring clamp to confirm a secure mechanical bond.
• Grounding: Where required, terminate shielded cables at the designated shield bus bar integrated within the cabinet, ensuring the ATC5S-00 is properly seated to maintain the common ground reference.
• Commissioning: Inspect all connections for mechanical integrity post-installation. Verify electrical continuity from the field termination point to the I/O module connector to ensure signal path continuity before powering the system.
