ATA4S-00 Yokogawa Pressure Clamp Terminal Block

Product Description

Configured for pressure signal termination in Yokogawa process control systems, the Yokogawa ATA4S-00 (ATA4S-00 Pressure Clamp Terminal Block) provides the physical connection between a pressure transmitter circuit and the associated I/O wiring. The supplied data identifies a pressure-clamp connection and does not establish a specific I/O module compatibility list.

Hardware Specifications

Process Instrument Signal Termination

The ATA4S-00 provides a physical termination point for a pressure transmitter circuit. The pressure transmitter converts process pressure into an electrical signal, while the terminal block provides the connection interface toward the control-system I/O wiring.

Because Yokogawa uses different terminal assemblies for different I/O architectures, the exact mating module should be confirmed from the applicable Yokogawa hardware documentation before installation.

The supplied description mentions that the "-00" suffix may indicate a configuration without a surge absorber. This point is not independently established by the supplied data, so the presence or absence of surge protection should be verified against the manufacturer's ordering information.

Frequently Asked Questions

Q: Is the ATA4S-00 an analog input module?
A: No. The supplied information identifies it as a pressure clamp terminal block. It provides the physical connection interface rather than performing signal processing.

Q: How many pressure transmitter connections does the ATA4S-00 support?
A: The supplied information identifies a single-channel configuration. A manufacturer datasheet should be used to verify the exact terminal assignment.

Q: Does the ATA4S-00 include surge protection?
A: The supplied information does not confirm built-in surge protection. The "-00" configuration is described as potentially having no surge absorber, but this requires manufacturer documentation for confirmation.

Field Installation Guidelines

Install the ATA4S-00 only with the Yokogawa I/O hardware and terminal arrangement specified for the applicable control-system configuration.

Verify the transmitter signal type, terminal assignment, and wiring polarity before connecting field conductors. Keep pressure transmitter signal wiring separated from AC power conductors and other high-level switching circuits.

Use appropriate shielded instrumentation cable where the system design requires shielding. Terminate the cable shield according to the Yokogawa grounding scheme rather than creating unintended ground loops.

Secure the pressure-clamp connection mechanically and check the associated tubing or process connection for correct engagement. Do not apply mechanical force to electrical terminals during tubing installation.

If surge protection is required, verify the exact ATA4S-00 configuration before installation. Do not assume that this terminal block provides transient protection unless the manufacturer's documentation explicitly specifies it.
