GE IS220PRTDH1B Input Module
GE IS220PRTDH1B
The GE IS220PRTDH1B is a high-performance RTD (Resistance Temperature Detector) input module developed by General Electric (GE) for the Mark VIe/Mark VI series control systems. It is specifically designed for temperature measurement and monitoring in industrial automation. The module delivers reliable temperature signal conversion in harsh environments such as power generation, oil, natural gas, metallurgy, and chemical industries. It supports single-machine or triple-redundancy configurations and is compatible with standard VME chassis dimensions.

Product Features
- High Reliability: Complies with industrial-grade temperature and humidity requirements, features a redundant design, and can be used in triple-redundancy systems.
- High-Speed Counting: Offers a maximum counting rate of 1 MHz, suitable for fast and accurate temperature sampling.
- Flexible Programming: Compatible with the programming environment of GE Mark VIe controllers, supporting multiple counting modes (up, down, quadrature).
- Rich Communication Options: Built-in Ethernet interface for direct access to industrial networks, enabling remote monitoring and data acquisition.
- Easy Installation & Maintenance: Adopts standard VME slots and a modular design for plug-and-play installation; allows quick replacement during maintenance without disrupting system operation.
Structure and Composition
- Module Body: VME standard-compliant chassis, including an RTD input card, signal conditioning circuit, A/D converter, microprocessor, and power management unit.
- Input Terminal Block: Dedicated terminals for each channel, supporting 3-wire or 4-wire RTD connections.
- Communication Interface: Dual Ethernet ports (optional) for network data transmission.
- Heat Dissipation Device: Natural convection heat sink to meet heat dissipation requirements during high-power operation.
Typical Application Fields
- Temperature monitoring of turbines in power plants
- Temperature measurement in oil and natural gas pipelines and refining processes
- Process control in metallurgical and chemical production lines
- Ambient temperature monitoring in mechanical manufacturing, building automation, and transportation systems
- Any industrial automation scenarios requiring high-precision, wide-temperature-range RTD inputs
Installation and Maintenance Guidelines
- Pre-Installation Check: Verify that the chassis dimensions match the cabinet specifications, and check the power supply voltage (24 V DC) and grounding conditions.
- Plug-in/Unplug Operation: Insert the module into the VME slot with power disconnected, ensuring the latch is securely locked. Always disconnect power before unplugging to avoid arcing.
- Wiring: Connect to the corresponding terminal block according to the RTD type (3-wire or 4-wire). Keep cable lengths uniform to prevent signal interference.
- Configuration: Set up channel mapping and counting modes in the GE Mark VIe control software, and calibrate the temperature range and accuracy.
- Routine Maintenance: Regularly check for dust accumulation on the heat sink; clean it and maintain natural ventilation. Monitor the module’s power consumption and temperature, and replace it promptly if abnormal heating occurs.
- Troubleshooting: Use the built-in Ethernet interface to read self-diagnostic information for quick identification of channel failures or communication interruptions.
