Configured for precision temperature data acquisition in Mark VIe and EX2100e control platforms, the GE IS220PRTDH1AD (IS220PRTDH1AD) RTD Input Module provides direct physical/electrical execution of sensor digitization and linearization tasks.

Module Configuration Matrix

• Model: IS220PRTDH1AD

• Series: Mark VIe / EX2100e

• Channels: 8 Differential RTD Inputs

• Communication: Dual redundant IONet (100 MB Ethernet)

• Form Factor: Terminal board-mounted pack

Hardware Specifications

Industrial Control & Processing Characteristics

The module utilizes backplane bus communication velocity to support 10 ms or 20 ms frame rates in deterministic control networks. It ensures I/O density scaling by supporting multiple RTD types, including 10 Ohm Copper, 100 Ohm Platinum, 120 Ohm Nickel, and 200 Ohm Platinum sensors. Firmware flash compatibility is managed via the IONet, allowing for seamless updates across distributed control nodes. The module architecture facilitates high-speed data acquisition with integrated signal conditioning, maintaining signal integrity and thermal measurement accuracy across the specified operating range.

Ordering Info

• One (1) IS220PRTDH1AD RTD input pack

• Standard terminal board mounting hardware

• Digital documentation package for Mark VIe integration

Field Installation Guidelines

• Terminal Board Mounting: Align the module with the designated slot on the TRTD terminal board. Press firmly until the connector pins are fully engaged.

• Securing: Use the integrated retention screws to fasten the module to the terminal board, ensuring consistent mechanical coupling and ground path continuity.

• Wiring: Terminate RTD field leads according to the terminal board wiring schematic; ensure differential pair shielding is grounded at the cabinet entry point.

• IONet Connection: Connect the dual RJ45 Ethernet ports to the redundant IONet switches. Verify link status LEDs to confirm network connectivity.

• Configuration: Assign channel parameters and sensor types through the ControlST or ToolboxST engineering interface prior to final system commissioning.

Frequently Asked Questions

• Q: Is this module hot-swappable?

  A: Yes, the IS220PRTDH1AD supports hot-swapping within the I/O rack during system operation, provided the redundant network maintains data availability.

• Q: Does the module support 3-wire RTD configurations?

  A: Yes, the module supports standard 2-wire, 3-wire, and 4-wire RTD configurations via appropriate terminal board wiring.

• Q: How are firmware updates performed?

  A: Firmware updates are pushed from the Mark VIe controller over the IONet, allowing for remote maintenance without physical module access.

• Q: Can I mix different RTD types on one module?

  A: Yes, each of the 8 channels can be independently configured for the supported RTD types (Copper, Platinum, or Nickel) through the software.

• Q: Does the module require external excitation for the RTDs?

  A: No, the module provides the necessary excitation current for all supported RTD types.

• Q: How does redundant IONet work?

  A: The module communicates simultaneously over two independent Ethernet ports; if one network path fails, the controller maintains communication via the secondary path.

• Q: What happens if an input goes open-circuit?

  A: The module detects the fault and reports a "Channel Fault" or "Open Circuit" status bit to the controller, which can be configured to trigger HMI alarms.

• Q: Is the resolution fixed?

  A: The module uses a 16-bit analog-to-digital converter to ensure high-resolution temperature measurement across the entire input range.
