Model Identification Matrix

• Model: IS220PRTDH1AD

• Series: Mark VIe / EX2100e

• Function: 8-Channel RTD Data Acquisition

• Protocol: Dual redundant IONet (100 MB Ethernet)

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. I/O density scaling is achieved through the integration of multiple sensor interface algorithms, supporting 10 Ohm Copper, 100 Ohm Platinum, 120 Ohm Nickel, and 200 Ohm Platinum inputs. Firmware flash compatibility via the IONet interface ensures the module maintains synchronization with the host control system software. Data processing includes real-time linearization of resistance inputs to digital values, executed locally to reduce controller overhead.

Field Installation Guidelines

• Terminal Board Interface: Align the module with the mating connector on the TRTD terminal board. Apply even pressure until the locking mechanism engages.

• Fastening: Secure the module using the built-in retention screws to maintain mechanical integrity and shield contact.

• Grounding: Terminate RTD shield drains to the designated chassis ground terminal on the terminal board to minimize common-mode noise.

• Network Cabling: Connect dual RJ45 patch cables to the IONet ports; ensure cables are routed through internal cabinet raceways to protect against physical damage.

• Verification: Confirm link activity through the engineering workstation; verify sensor readings against known calibration references during I/O loop check.

Frequently Asked Questions

• Q: Is this module hot-swappable?

  A: Yes, the module supports hot-swapping under normal operating conditions when installed in a dual redundant IONet configuration.

• Q: How does the module handle sensor faults?

  A: It detects open-circuit or short-circuit conditions on individual channels and transmits a fault status word to the host controller for HMI annunciation.

• Q: Does the module require manual calibration?

  A: No, the module is factory-calibrated; field calibration is performed through software offsets in the ToolboxST application.

• Q: Can I use 2-wire RTDs?

  A: Yes, the terminal board wiring can be configured for 2-wire, 3-wire, or 4-wire RTD input types.

• Q: How is redundancy managed?

  A: The module maintains dual active connections to redundant IONet switches; communication failover occurs automatically if one network path is interrupted.

• Q: What is the primary function of the 16-bit resolution?

  A: The 16-bit resolution ensures high-fidelity temperature data acquisition, minimizing quantization errors in critical thermal monitoring loops.

• Q: Is the module firmware field-upgradable?

  A: Yes, firmware is updated remotely from the engineering workstation through the IONet connection.

• Q: Does the module consume power from the sensor loop?

  A: No, the module provides its own isolated excitation current for all 8 RTD channels.
