Yokogawa ATRBS-00 S2 Terminal Module

The Yokogawa ATRBS-00 S2, also cataloged as the ATRBS Terminal Module, operates as a dedicated hardware component for multi-signal field device interfacing and signal transmission within CENTUM VP / CENTUM CS 3000 control architectures. Configured to handle analog, digital, and pulse inputs, this module provides direct physical execution of loop wiring convergence. It maintains strict signal integrity without introducing processing latency.

Hardware Specifications

Process Signal Interfacing & Channel Isolation Characteristics

• Multi-Signal Loop Routing: Accepts analog, digital, and high-speed pulse inputs, optimizing the 4-20 mA HART loop protocol interface between field instruments and node controllers.
• High-Accuracy Line Integrity: Maintains a measurement precision of +/-0.01% FS while minimizing signal distortion across high sampling rate bands up to 100 kHz.
• Channel Noise Suppression: Minimizes crosstalk and line capacitance variations without compromising internal cold junction compensation parameters on high-density process channels.

Frequently Asked Questions

Q: Does the ATRBS-00 S2 terminal module require external power to process signal lines?

A: No, the module operates as a passive signal termination component within the DCS backplane ecosystem, deriving minimal operating bias directly from the parent I/O rack.

Q: How does the wide operating temperature range impact field cabinet deployment?

A: The rated operating range of -40 to 70 deg C allows direct mounting in unconditioned remote field marshaling enclosures without requiring secondary climate control equipment.

Field Installation Guidelines

1. DIN-Rail / Rack Mounting: Fasten the terminal module securely to the panel rack or DIN-rail structure inside an IP54-rated marshaling cabinet to shield terminals from ambient moisture and dust exposure.
2. Terminal Wiring Procedure: Strip field wire insulation to 7 mm and clamp tightly into the terminal block screws, ensuring torque does not exceed 0.5 Nm to prevent connector damage.
3. Shielding & Grounding Integrity: Connect all field cable shield drain wires directly to the cabinet ground bus bar. Verify that ground loop impedance remains under 1 ohm to sustain high signal accuracy.
4. Signal Separation: Route low-voltage analog and pulse signal cables in dedicated wire trays physically separated from high-voltage AC power distribution lines by at least 300 mm.
