Overview Manuals Specifications Application Scenarios Diagnostics Connectivity

Features:

  • Provides dual-mode analog output capability supporting both voltage and current signal transmission.
  • Designed with defined safety electrical limits ensuring controlled output energy characteristics.
  • Compatible with dedicated Mark VIe terminal boards for structured system integration.
The IS220PAOCH1BE is an analog output module designed for the Mark VIe control system, providing stable signal generation for industrial process control environments. It operates within a defined voltage supply range and delivers both voltage and current outputs, enabling flexible integration into different control loop configurations. Its electrical design ensures consistent signal behavior under standard operating conditions.

In practical applications, IS220PAOCH1BE works together with designated IS200 terminal boards, forming a complete interface between the control system and field wiring. This structured pairing ensures that analog signals are properly routed and maintained across the control architecture. The module supports both standard and safety-related operational requirements, making it suitable for regulated industrial systems.

The IS220PAOCH1BE also includes defined environmental and safety classifications, allowing operation across a wide temperature range and under T4 classification conditions. Its compatibility with approved terminal board combinations ensures correct installation in hazardous location configurations. This makes IS220PAOCH1BE a reliable component within GE Mark VIe analog output architectures.

The IS220PAOCH1BE General Electric Analog Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Steam Turbine Control: Outputs precise current signals to drive servo valves or regulating valves, controlling the fuel ratio and steam flow rate of gas turbines or steam turbines.
  • Power Plant Auxiliary Systems: Used in DCS systems to regulate pump speed, damper opening, and heat exchanger liquid level, achieving complex loop PID control.
  • Safety Management System: Deployed in the Mark VIeS safety loop, executing the linkage of critical actuators in emergency situations.
  • Legacy System Upgrade: As a key hardware component in the migration from Mark VI to the Mark VIe platform, it replaces outdated VME architecture boards to extend asset lifespan.
  • Feedback Verification: The module has a built-in analog-to-digital converter (ADC) that can read and verify the current feedback of each output channel in real time, ensuring that the command value matches the actual output.
  • Fault Location: Equipped with dedicated diagnostic indicator lights (LEDs), it can visually display the module's operating status, hardware faults, and communication link anomalies, assisting in quickly locating on-site problems.
  • Status Tracking: Combined with ToolboxST software, it supports high-precision timestamp recording (SOE), providing millisecond-level diagnostic data when the system experiences disturbances.
  • Loop Monitoring: It can automatically detect open or short circuit states in the output loop and trigger alarms at the control layer to prevent uncontrolled regulation due to line disconnection.
  • Redundant Communication: Equipped with dual RJ-45 Ethernet interfaces, it supports connection to redundant IONet networks, ensuring that control commands can still be transmitted normally even if a single network path is damaged.
  • Power Integration: It adopts a three-pin dedicated power input interface to provide stable DC power to the internal processor board (BPPx) and acquisition board.
  • Direct Plug-in/Pull-out: It directly connects to relevant terminal boards (such as TBAOH1C) via a DC-37 pin connector, simplifying cabinet wiring and reducing contact resistance.
  • System Integration: It exists as an "I/O Pack," eliminating the need for a backplane bus. It can be distributed and installed closer to field devices, and remotely accessed to the main controller via fiber optic or twisted-pair cables.
Description
The IS220PAOCH1BE is an analog output module within the Mark VIe control platform, operating with a power supply voltage range of 27.4–28.6 Vdc (nominal 28 Vdc) and a maximum supply current of 0.45 A. It provides analog output capabilities with voltage output from 0 to 18 Vdc and current output from 0 to 20 mA dc, supporting flexible signal delivery in control loops.

The module is designed to operate within an ambient temperature range of -30 °C to +65 °C and is classified under temperature class T4. Its intrinsic safety-related parameters include Uo = 28.6 Vdc, Io = 22.5 mA, Po = 0.641 W, Co = 0.255 μF, and Lo = 100 mH, defining its electrical output limits and safe energy characteristics.

The IS220PAOCH1BE is intended for use with dedicated terminal board accessories, including IS200STAOH1A, IS200STAOH2A, and IS200TBAOH1C. These combinations ensure proper electrical interfacing between the I/O pack and field wiring within the Mark VIe system architecture.

In hazardous location configurations, the IS220PAOCH1BE is approved for use only when paired with the specified IS200 terminal boards. This structured compatibility ensures that the analog output module maintains correct operational integrity within certified industrial control environments.
