ATR8D-00 Yokogawa Dual Pressure Clamp Terminal Block

Overview

Configured for RTD signal termination in CENTUM VP and ProSafe-RS I/O systems, the Yokogawa ATR8D-00 (ATR8D Dual Pressure Clamp Terminal Block) provides direct physical connection between field wiring and RTD input modules.

Hardware Specifications

Yokogawa DCS RTD Signal Interface Characteristics

The ATR8D-00 operates as a passive interface component between field RTD wiring and Yokogawa input modules. It maintains channel separation through isolated terminal arrangements and supports stable resistance measurement signal transmission.

Furthermore, the terminal block structure uses pressure clamp connections to reduce wiring stress caused by vibration and mechanical movement. The design supports industrial instrumentation requirements where RTD signals require controlled routing and electrical separation.

For Yokogawa process control architectures, the terminal interface supports channel-to-channel isolation practices used in DCS instrumentation wiring. The component does not process measurement data; instead, it provides the physical termination path required by RTD input circuits.

Frequently Asked Questions

Q: Does the Yokogawa ATR8D-00 require an external power supply?
A: No. The ATR8D-00 is a passive terminal block and does not consume electrical power. It provides field wiring termination only.

Q: What type of input signals can connect to the ATR8D-00?
A: The ATR8D-00 is designed for RTD input module connections and supports field RTD wiring termination through Yokogawa compatible I/O configurations.

Q: Can the ATR8D-00 perform signal conversion or isolation processing?
A: No. Signal conversion and measurement processing are performed by the connected Yokogawa RTD input module. The ATR8D-00 provides physical connection and wiring organization.

Field Installation Guidelines

• Install the ATR8D-00 according to the applicable Yokogawa I/O module installation manual and terminal assignment documentation.
• Verify RTD wiring polarity and channel allocation before connecting field cables.
• Maintain proper separation between RTD signal cables and high-voltage power cables to reduce electrical interference.
• Connect cable shields according to the plant grounding standard and avoid unnecessary shield loops.
• Confirm that terminal connections are mechanically secured before system commissioning.
• Inspect wiring routes for vibration exposure and ensure that field cables have adequate mechanical support.
