Functional Description

IS230SHRA2ASHRA2AG01 is a Dual HART Analog I/O Assembly developed by GE. It is a part of Mark VI control system. It is designed to provide both analog input and analog output capabilities while supporting HART® (Highway Addressable Remote Transducer) communication. This enables advanced interaction between the control system and HART-enabled field devices, making it an ideal choice for industrial environments requiring precise signal processing and intelligent device communication.

Assembly Composition

The assembly consists of two main components:

• Terminal Board (SHRA) – A compact analog input/output terminal board that handles signal connections.
• I/O Pack (PHRA or YHRA) – The processing unit that interfaces with the Mark VI control system.

The terminal board is specifically engineered to accept 10 analog inputs and two analog outputs, providing flexible connectivity options for a range of field instruments.

HART Communication Capabilities

The SHRA terminal board is HART-enabled, allowing bi-directional digital communication over the same wiring used for analog signals. This means it can pass HART messages between the PHRA I/O pack and HART-compatible field devices. This functionality allows for advanced diagnostics, device configuration, and real-time monitoring without additional wiring.

Input and Output Specifications

Analog Inputs:

• Total: 10 channels
• Compatible with two-wire, three-wire, four-wire, or externally powered transmitters.
• Provides flexibility for different sensor and transmitter configurations.

Analog Outputs:

• Total: 2 channels
• Output range: 4–20 mA
• Designed for precise control signal transmission to field devices such as actuators or control valves.

Note: Only a simplex version of the SHRA board is available.

Diagnostic Features

• Output Health Monitoring – The board measures the voltage drop across a series resistor to determine output current. If either of the two outputs becomes unhealthy, the I/O processor generates a diagnostic alarm (fault).
• Connector Identification System – Each cable connector on the terminal board is equipped with its own ID device (read-only chip) containing:
  • Terminal board serial number
  • Board type
  • Revision number
  • Connector location (JR, JS, JT)
• The I/O processor interrogates this ID chip to verify compatibility. If a mismatch is detected, a hardware incompatibility fault is triggered, preventing incorrect board usage
