Overview Manuals Specifications Input Types Measurement Installation

Features:

  • Sixteen Individually Isolated TC/mV Input Channels
  • Supports Eight Thermocouple Types and Two Millivolt Ranges
  • Cold-Junction Compensation with Configurable Burnout Direction
The Yokogawa AST143-S00 acquires thermocouple and low-level millivolt signals for FIO Field Control Units. Each of its sixteen isolated channels can be selected for the supported TC type or mV range.

Cold-junction compensation and selectable UP or DOWN burnout behavior support controlled temperature measurement. The built-in barrier separates the field interface from the system.

Before ordering the Yokogawa AST143-S00, confirm the complete suffix code, channel requirements, terminal block, and Field Control Unit configuration.

Description
The Yokogawa AST143-S00 is a sixteen-channel TC/mV input module with a built-in barrier for CENTUM VP Field Control Units. Each channel can be configured for a documented thermocouple type or millivolt input range.

The module accepts B, E, J, K, N, R, S, and T thermocouples together with -100 to 150 mV and -50 to 75 mV ranges. Individual channel selection, cold-junction compensation, and configurable burnout direction support structured signal acquisition.

Its built-in barrier provides galvanic isolation between the field interface and the system. Yokogawa specifies the module for Zone 2 or Division 2 installation under the documented conditions.
