Product Description
The ATA4S-00 S2 is a high-reliability 16-channel terminal block interface designed for the CENTUM VP and ProSafe-RS control systems from Yokogawa Electric Corporation.
This module provides a secure physical wiring interface between field instruments and DCS I/O modules such as AAI143 or ADV151. It uses vibration-resistant spring pressure clamp technology, which maintains stable electrical contact even in high-vibration industrial environments such as refineries, compressor stations, and power generation facilities.
The S2 hardware revision is optimized for compatibility with Yokogawa KS-series signal cables, enabling efficient integration between field wiring and control system electronics while reducing installation errors and maintenance requirements.
The terminal block supports universal signal types, including analog process signals (4–20 mA, 1–5 V DC) and digital I/O signals (24 V DC). Its compact design allows high-density cabinet wiring while maintaining high signal integrity.

Installation and Maintenance Advantages
The ATA4S-00 S2 is designed to reduce commissioning and maintenance workload through:
-
Tool-less wiring installation using spring clamp technology
-
Elimination of periodic screw re-torque maintenance
-
High resistance to mechanical vibration and thermal expansion effects
-
Compact DIN rail mounting for marshaling cabinet optimization
These features make it particularly suitable for remote installations and hard-to-access control cabinets.
FAQ
How does the pressure clamp compare to M4 screw terminals?
The spring clamp design provides stronger long-term contact stability and better resistance to vibration and thermal cycling compared to traditional screw terminals, reducing the risk of loose wiring and intermittent signal loss.
Is this terminal block compatible with redundant I/O?
Yes. The ATA4S-00 S2 provides dual KS cable ports on the rear side, enabling connection to redundant I/O modules to maintain signal continuity if one communication path fails.
Does it support HART communication?
Yes. The terminal block is electrically transparent to HART digital signals, allowing bidirectional communication when used with HART-enabled I/O modules.
