Product Description
The A1BA4D is a high-reliability interface terminal board designed for integration with Yokogawa distributed control architectures, including systems such as Yokogawa CENTUM VP and Yokogawa CENTUM CS 3000. It provides a stable connection interface between field instrumentation and analog I/O modules, supporting both single-loop operation and dual-redundant configurations.
The specific variant A1BA4D-06 incorporates ISA Standard G3 conformal coating, offering enhanced resistance to corrosive industrial atmospheres. This protective coating helps ensure long-term reliability in environments where corrosive gases may be present. However, the board is designed for installation in non-explosion-protected areas.
Engineered with flexible channel configuration, the board can support either a 16-channel configuration or an 8-channel subset, depending on the connected I/O module requirements. Its DIN rail mounting structure enables secure and vibration-resistant installation within standard control cabinets, making it suitable for demanding industrial automation systems.

Redundancy and Configuration
When deployed in dual-redundant mode, the A1BA4D allows two I/O modules to connect to the same set of field terminals. This architecture ensures that if one module fails, the standby module continues processing the signal without interrupting the control loop. Such redundancy is particularly valuable in mission-critical industrial processes where continuous operation and system availability are essential.
Frequently Asked Questions
Q: What does the “G3” suffix indicate for this terminal board?
A: The G3 designation follows the ISA-S71.04 environmental classification, indicating that the circuit board is treated with conformal coating to resist corrosive industrial gases such as sulfur- or chlorine-based compounds. This protection improves long-term reliability in harsh plant environments.
