Overview

The IS220PAICH2A is an analog I/O module developed by General Electric, part of the Mark VIe Speedtronic control system. This module is designed for seamless integration with terminal boards and is used to interface analog signals to the controller.

Key Specifications

• Product Type: Analog I/O Module
• Series: Mark VIe
• Inputs:
  • 8 inputs: Selectable between 5 V, 10 V, or 4-20 mA current loop
  • 2 inputs: Selectable between 1 mA or 4-20 mA current
• Outputs:
  • 2 current loop outputs (0-20 mA)
  • Additional 0-200 mA output (on the first output only)
• Connectivity:
  • Dual RJ-45 Ethernet connectors for communication
  • DC-37 pin connector for field device communication
• Power: Powered by a three-pin connector
• LED Indicators: Visual diagnostics
• Supported Systems: Can operate in simplex mode with a TMR-capable terminal board

Installation

• Mounting: Securely mount the terminal board and insert the I/O pack into the connectors.
• Ethernet Connections: Connect one or two Ethernet cables based on configuration, typically ENET1 to the R controller network.
• Power Connection: Power is supplied via a three-pin connector, with inherent soft-start capabilities to control inrush current.

Additional Hardware Features

• Add-on Daughterboard: Includes hardware support for adding 0-200 mA output capability to analog output 1.
• Power Dissipation Management: The 200 mA output power is derived from a variable voltage source on the daughterboard to reduce linear output transistor power dissipation.
