Yokogawa ATRBS-00 S2 Terminal Module

The Yokogawa ATRBS-00 S2, also cataloged as the ATRBS-00 Terminal Module, operates as a dedicated hardware component for signal distribution and termination within CENTUM VP and CS 3000 platforms. It conditions incoming instrumentation lines and routes isolated field signals directly to host system I/O modules across internal system backplanes.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The ATRBS-00 S2 provides high-speed field signal termination and noise attenuation across process control loops. Optimized for 4-20 mA HART loop protocol instruments and high-speed data acquisition channels, the terminal module maintains measurement precision up to +/-0.01% Full Scale across a broad sampling spectrum from 1 Hz to 100 kHz. The internal circuitry limits channel-to-channel isolation degradation, preventing transient ground loop currents from interfering with low-level analog signals before pass-through to the central control processors.

Frequently Asked Questions

Q: What operational changes were introduced in the S2 revision of the ATRBS-00 module?

A: The S2 revision incorporates enhanced hardware build quality and optimized thermal dissipation profiles, extending the ambient operating range from -40 to +70 deg C.

Q: Does the ATRBS-00 S2 require an independent external DC power connection?

A: No, the module draws its operating power directly through the host backplane connection when mounted into the terminal slot.

Q: What input sampling rates are supported by the ATRBS-00 S2 terminal hardware?

A: The module architecture supports signal sampling rates ranging from 1 Hz for standard process variables up to 100 kHz for high-speed dynamic acquisition.

Field Installation Guidelines

• Anti-Static Precautions: Always wear a grounded ESD wrist strap when handling the terminal assembly to protect internal surface-mount components.
• Mounting Security: Align the unit with the chassis guide slots and slide inward until the backplane locking mechanism engages cleanly. Tighten all retention screws.
• Cable Shielding: Terminate field wiring drain wires to the dedicated system ground bus at a single earthing point to maintain noise immunity.
• Routing Separation: Keep low-level field signal conductors separated from AC power distribution lines by at least 300 mm within cabinet wire trunks.
