PLCs, Power Supplies & Others

The Yokogawa AAI141-H00/K4A00 is a fully configured 16-channel analog input module featuring integrated HART communication and the ATK4A-00 KS Cable Interface Adapter. This complete assembly connects directly to AEA4D terminal boards without additional cabling components. It delivers high-density analog acquisition with full digital device access.

Key Technical Specifications

Complete Factory-Configured HART Solution

The AAI141-H00/K4A00 arrives as a fully assembled and tested unit. You receive both the 16-channel HART input module and the ATK4A-00 KS Cable Interface Adapter in one orderable configuration. This eliminates separate procurement and ensures guaranteed compatibility. Consequently, you reduce engineering effort and procurement complexity.

Sixteen Channels of Simultaneous HART Communication

Every analog input channel on this module supports full HART digital communication. You access device diagnostics, secondary process variables, and configuration parameters directly through the DCS. The AAI141-H00/K4A00 requires no external HART multiplexers or standalone modems. Therefore, you achieve significant hardware cost avoidance.

ATK4A-00 KS Cable Interface Adapter

The included ATK4A-00 adapter provides the physical interface between module electronics and KS cabling. This device conditions signals for reliable HART communication over standard Yokogawa KS cables. You simply connect the adapter to your AEA4D terminal board. Installation becomes truly plug-and-play.

Optimized for AEA4D Terminal Board Integration

This configuration specifically supports AEA4D series termination boards. The ATK4A-00 adapter mates directly with the board’s KS cable connector. Field wiring terminates at the board while the AAI141-H00/K4A00 handles all signal processing. This separation enables hot-swap module replacement without rewiring.

Non-Isolated Architecture for Cost-Effective Scaling

The AAI141-H00/K4A00 employs non-isolated channel design throughout. You therefore achieve sixteen HART-capable inputs in a single node slot. All channels share a common analog ground reference. This architecture delivers the lowest installed cost per HART point in the CENTUM product family.

High-Speed Analog Data Path

Despite HART digital communication, analog update rate remains 100 samples per second. You receive refreshed process variables every 10 milliseconds. This performance supports closed-loop control applications. The AAI141-H00/K4A00 therefore suits both monitoring and regulatory control functions.

Mechanical Integration Specifications

The complete assembly occupies one standard ESB or ER bus node slot. Module weight totals 0.4 kilograms with the ATK4A-00 adapter attached. Operating temperature range from -10 °C to +55 °C accommodates control room environments. The KS cable connection provides secure mechanical latching.

Power Supply Considerations

This configuration requires both 5 V DC and 24 V DC power sources. The AAI141-H00/K4A00 consumes 320 mA from the logic supply at 5 volts. Field power consumption reaches 480 mA at 24 volts DC. The ATK4A-00 adapter draws power directly from the module bus.
