Yokogawa ASR133-S00 ATSR3S RTD/POT Input System

The Yokogawa ASR133-S00, also cataloged as the ASR133 RTD/POT Input Module, operates as a dedicated hardware component for temperature and potentiometer analog telemetry acquisition within CENTUM VP, CENTUM CS, and CENTUM XL platforms.

Hardware Specifications

Process Control & DCS Instrumentation Properties

The Yokogawa ASR133-S00 utilizes extensive channel-to-channel isolation parameters to block field-side common-mode noise spikes from disrupting adjacent temperature measurement networks. The module works directly with the ATSR3S pressure clamp assembly, using tool-free connection plates to eliminate terminal resistance changes caused by mechanical relaxation. When running resistance temperature detector tracks, the underlying logic evaluates real-time line resistance compensation schedules across 3-wire and 4-wire layouts, preventing thermal gradients from shifting accuracy across the 8-channel analog acquisition layout.

Frequently Asked Questions

Q: How does the system handle high-resistance signal variations over extended 2-wire RTD field layouts?

A: 2-wire runs are susceptible to copper lead-wire resistance anomalies which induce temperature measurement drift. For high-accuracy process loops, you must use 3-wire or 4-wire hardware configurations to let the internal computing layer actively track and cancel line resistance deviations.

Q: Is hot-swapping or live wiring modification permitted directly at the ATSR3S terminal block?

A: No. The ATSR3S pressure-clamp assembly is not hot-swappable. You must completely de-energize the field wiring paths before inserting or releasing conductors to prevent electrical transients from passing back into the active ASR133 input module.

Q: Where are the primary galvanic isolation circuits located within this dual-component system?

A: The physical ATSR3S terminal block functions purely as a dry wiring routing interface and contains no signal processing circuits. The 1500 VAC dielectric strength and isolation shielding are located inside the paired ASR133 module housing.

Field Installation Guidelines

• Pressure-Clamp Terminal Insertion: Push a small terminal tool or small screwdriver into the actuation slot to open the internal clamp, insert the stripped lead wire, and remove the tool. This screw-less mechanism maintains constant tension to prevent connections from loosening due to cabinet vibration.
• Shield Continuity Management: Run all RTD and potentiometer lines inside dedicated instrument cables with an overall shield. Connect the drain wires to the system earth bus bar at the cabinet entry bulkhead, keeping them isolated from high-current AC grounding networks.
• Parallel Signal Cable Routing: Maintain a minimum clearance distance of 30 cm between the analog input lines and high-voltage AC lines or motor power circuits. Crossing power and signal lines at right angles minimizes electromagnetic cross-talk.
• Redundancy Slot Configuration: When deploying single-channel redundancy logic, verify that both matching input pathways map to identical channel assignments within the system builder workspace before putting the loops into service.
