Foxboro FBM202 thermocouple input module

Foxboro FBM202 thermocouple input module

Technical Specification
Input channels: 8 independent isolated thermocouple /mV input channels, and an additional 1 isolated cold-end reference temperature compensation channel.
Input range: -10.5 to + 69.5mV dc.
Accuracy: mV input is ±0.03% (±24μV) of the range at 25℃; The RTD channel is ±0.03% of the range. The consistency of the RTD reference junction is ±0.25℃. The consistency of the RTD thermocouple is ±0.25℃.
Input open-circuit voltage: 250mV dc through 10MΩ (mV channel).
A/D conversion: Each channel uses an independent sigma-delta converter for A/D signal conversion, providing new analog input readings every 25 milliseconds.
Typical thermocouple types: B, E, J, K, N, R, S, T and other mV signals.
Thermocouple burnout detection: Full-scale value.
Input channel isolation: Each channel is isolated from all other channels and grounding current, and can withstand 600V ac voltage for 1 minute.
Power supply requirements: The input voltage range is 24V dc +5%, -10%, and the power consumption is 3W (maximum value).
