Description

Yokogawa ATSR3S-0 Pressure Clamp Terminal Block

The Yokogawa ATSR3S-0, also cataloged as the ATSR3S-0 Pressure Clamp Terminal Block, operates as a dedicated hardware component for connecting RTD and POT field devices to CENTUM DCS platforms. It provides a secure, isolated interface to ASR133 modules, enabling analog signal transmission without external barriers.

Process ControlI ntegration Features

• Channel-to-Channel Isolation: Each input channel maintains galvanic separation, preventing cross-channel interference and preserving analog signal integrity.
• Cold Junction Compensation (CJC): Integrated compensation for RTD signals ensures accurate temperature readings without additional external devices.
• Loop Protocol Compatibility: Supports standard 4-20 mA analog input signals and can interface with HART-enabled devices when paired with compatible modules.

Frequently Asked Questions

Q: VnA: Can ATSR3S-0 terminals be hot-swapped during operation?
A: No. Field wiring to ATSR3S-0 must be de-energized before connecting or disconnecting to avoid signal disruption.

Q: VnA: What is the maximum RTD length supported without degrading accuracy?
A: Standard industrial practice limits total lead resistance to maintain measurement accuracy; 3-wire or 4-wire connections are recommended for long distances.

Q: VnA: Does the terminal block support external surge protection?
A: ATSR3S-0 relies on the ASR133 module's built-in isolation barrier; external surge absorbers can be added separately if system-level protection is required.

Field Installation Guidelines

1. Mount ATSR3S-0 on the designated ASR133 module ensuring full mechanical engagement.
2. Route field wiring through properly shielded and grounded conduits to minimize electrical noise.
3. Connect RTD or POT leads according to 2-wire, 3-wire, or 4-wire configuration requirements.
4. Verify torque and seating of pressure clamps; no screw adjustment is needed, but visual confirmation is required.
5. Maintain separation from high-voltage power lines to prevent inductive coupling.
6. Inspect connections periodically for corrosion or mechanical loosening in harsh environments.
