Yokogawa ATR8S-00 S2 Single Analog Temperature Terminal

The Yokogawa ATR8S-00, also cataloged as the ATR8S-00 Pressure Clamp Terminal Block, operates as a dedicated hardware component for specific technical task within CENTUM VP and CS 3000 Field I/O (FIO) subsystems platforms. This hardware component functions as the physical interface point routing 8-channel temperature inputs from Resistance Temperature Detector (RTD) and Thermocouple (TC) sensors directly to the internal processing architecture of the system.

Process Control and Signal Condition Isolation

The structural engineering of this module integrates a specialized spring-loaded pressure clamp mechanism, which ensures a gas-tight seal across all 8 input channels to suppress contact resistance under high vibration profiles. The architecture utilizes precise channel-to-channel isolation parameters to isolate low-voltage sensor circuits from adjacent loop noise and electrical transients. Temperature measurement signals undergo internal reference routing where cold junction compensation (CJC) takes place at the point of termination, ensuring precise voltage-to-temperature linearization for active thermocouple loops. This physical design limits thermal gradients across the terminal matrix, preventing ambient environmental drift from corrupting data transmission.

Frequently Asked Questions

Q: Does the ATR8S-00 terminal block support active online hot-swap operations?

A: No, physical removal or connection of this terminal block must take place while the corresponding input loop power is isolated to prevent transient spikes or open-circuit diagnostic triggers within the processing logic.

Q: What specific wiring limits apply to the terminal interfaces for RTD configurations?

A: The pressure clamp terminal matrix supports standard 3-wire and 4-wire RTD configurations, utilizing direct electrical contacts to optimize lead wire resistance matching.

Field Installation Guidelines

Mount the unit directly onto the matching Yokogawa FIO I/O module base, ensuring the mechanical alignment pins engage fully into the backplane seat.
Insert the stripped sensor wires straight into the M3.5 pressure clamp terminal openings until the internal spring mechanism establishes a complete gas-tight hold.
Route all low-voltage thermocouple and RTD signal conductors through independent, grounded steel conduits to separate them from adjacent high-voltage power lines.
Terminate all overall cable shields directly at the dedicated low-impedance grounding bar within the control cabinet enclosure to prevent stray noise collection.
Inspect terminal contacts periodically under extreme thermal cycling conditions to confirm the mechanical spring force remains optimal over long-term operation.
