ATSA3S-0 Yokogawa Pressure Clamp Terminal Block

Hardware Specifications

DCS Analog Signal Interface and Intrinsic Safety Wiring

The ATSA3S-0 provides a dedicated terminal interface between field devices and Yokogawa analog input modules equipped with internal intrinsic safety barriers. It maintains the required electrical separation for hazardous-area signal connections.

Furthermore, the pressure clamp terminal design allows direct field cable termination without conventional screw tightening. The compact structure supports high-density cabinet installation for CENTUM FCS configurations.

For Yokogawa process control applications, the terminal block operates with analog instrumentation loops, including transmitter wiring connected through supported analog input modules. The interface supports channel-to-channel isolation requirements and maintains signal separation between individual field circuits.

Frequently Asked Questions

Q: Is the ATSA3S-0 an active I/O module with signal processing capability?
A: No. The ATSA3S-0 is a passive pressure clamp terminal block. It provides field wiring termination and signal routing for compatible analog input modules.

Q: Which Yokogawa module is compatible with the ATSA3S-0?
A: The ATSA3S-0 is designed for use with the Yokogawa ASI133 analog input module with built-in intrinsic safety barrier functions.

Q: Does the ATSA3S-0 require an external power supply connection?
A: No. The terminal block does not require external power. The connected I/O module performs signal measurement and processing functions.

Field Installation Guidelines

Install the ATSA3S-0 inside the designated FCS cabinet location according to Yokogawa cabinet assembly instructions.

Verify terminal assignments before connecting field wiring to prevent channel mapping errors. Use appropriate cable types for analog instrumentation signals and maintain separation between signal wiring and high-voltage power conductors.

Connect cable shields according to the system grounding design. Avoid unnecessary shield loops and maintain proper grounding practices for analog signal integrity.

Confirm that field devices, intrinsic safety requirements, and associated I/O modules match the approved Yokogawa system configuration before commissioning.
