I/O modules

This VME-based RTD module converts resistance signals into accurate temperature readings. The GE IS200VRTDH1D IS200VRTDH1DA accepts up to twelve independent RTD input channels. Each channel supports 2-wire, 3-wire, or 4-wire RTD configurations for maximum flexibility. Consequently, operators can monitor bearing temperatures, stator windings, or exhaust gases with high precision.

Technical Specifications of the RTD Module

The GE IS200VRTDH1D IS200VRTDH1DA fits a standard VME 6U form factor seamlessly. Its height measures 233.4 mm, and its depth reaches 160 mm. The board weighs approximately 0.55 kg including all signal conditioning components. A single front panel LED indicator shows channel status and fault conditions at a glance. The rear side uses a 64-pin DIN 41612 connector for backplane signals and power. This design stores minimal energy in small filtering capacitors only. Therefore, the board contains no batteries or large energy storage elements.

Functional Features and Signal Conditioning

The GE IS200VRTDH1D IS200VRTDH1DA automatically compensates for lead wire resistance on 3-wire and 4-wire connections. You can select the excitation current source per channel independently. The onboard firmware performs linearization for Pt100 and Ni120 sensor types. Each channel also includes open-circuit detection for immediate fault reporting. Consequently, operators receive alerts for broken or disconnected sensors instantly.

Installation and System Integration

You must install this RTD module into any standard VME backplane chassis. The GE IS200VRTDH1D IS200VRTDH1DA requires no field wiring connections directly on the board. Instead, use a compatible termination panel like the IS200TRTDH1C for all sensor wiring. A 64-pin ribbon cable links the module to the termination panel securely. Always verify channel assignments before applying power to the system.

Maintenance and Operational Benefits

Because the GE IS200VRTDH1D IS200VRTDH1DA stores no battery-backed data, it requires no periodic battery replacement. Technicians can remove and reinstall the board without losing calibration settings. The Flash memory retains all configuration parameters indefinitely. Consequently, system maintenance becomes simpler and less time-consuming compared to battery-dependent designs.
