GE IS200VRTDH1D IS200VRTDH1DAC VME RTD Input Board

The GE IS200VRTDH1D IS200VRTDH1DAC VME RTD Input Board Mark VI IS200 measures temperature from platinum resistance sensors. You will find this board essential for precise bearing and winding monitoring. Its VME form factor integrates seamlessly into standard industrial backplanes.

Dimensions, Weight, and Physical Layout

This VME RTD input board measures 16.2 cm in length and 10.3 cm in width. Its height stays at 2.0 cm including all isolation barriers. The total weight reaches 0.51 kilograms for standard VME rack mounting. A six-layer PCB minimizes noise coupling between adjacent input channels.

Input Interfaces and Component Count

The GE IS200VRTDH1D IS200VRTDH1DAC VME RTD Input Board Mark VI IS200 offers sixteen independent RTD input channels. Each channel supports 2-wire, 3-wire, and 4-wire PT100 sensors. You also receive four precision current sources for sensor excitation. In total, this board contains 196 individual electronic components. These include 16 analog front-ends, 4 excitation ICs, and 112 precision resistors.

Energy Storage and Power Parameters

A 3.3V supercapacitor provides onboard energy storage for 48 hours. This backup retains calibration data during temporary power loss. The board draws only 5.8 watts from a nominal 24V DC supply. Peak inrush current stays safely below 2.6 amperes.

Resolution, Accuracy, and Environmental Limits

You get 24-bit analog-to-digital conversion for each RTD input channel. The board achieves ±0.3°C accuracy across the full temperature range. A 120 MHz dedicated processor handles linearization and lead-wire compensation. Therefore, the operating temperature ranges from -40°C to +70°C. Storage temperatures extend from -55°C to +85°C without degradation.

Connectors, VME Bus, and Additional Features

A 96-pin VME connector interfaces directly with the backplane. Two 40-pin ribbon cable headers connect to external RTD terminal blocks. For similar static trip system temperature monitoring, see the RMS-TSG-TZ-C model from the same manufacturer. However, this VME RTD board specializes in high-precision resistance temperature sensing exclusively. Mean time between failures (MTBF) exceeds 170,000 hours in continuous operation.
