FAQ
1. What is the Foxboro FBM202 RH926EQ?
The Foxboro FBM202 RH926EQ is a Thermocouple/mV Input Module used in Foxboro I/A Series 200 control systems. It is designed to acquire low-level thermocouple and millivolt signals for industrial temperature monitoring and process control applications. The FBM202 is the model designation, while RH926EQ is the corresponding order number.
2. How many input channels does the FBM202 provide?
The FBM202 provides eight isolated and independent thermocouple/mV input channels. Each channel is electrically isolated from the other input channels and from ground, which helps reduce the influence of ground potential differences and electrical interference between field signals.
3. What thermocouple types are supported by the FBM202?
The module supports common thermocouple types including B, E, J, K, N, R, S, and T. The appropriate thermocouple type must be configured in the control system according to the actual sensor installed in the field. Incorrect thermocouple type selection can result in significant temperature measurement errors.
4. How does the FBM202 provide reference-junction compensation?
The module includes one isolated reference-junction temperature compensation channel. Reference-junction measurement is provided by a 4-wire, 100 Ω platinum RTD installed in the compatible termination assembly. This allows the control system to compensate for the temperature at the thermocouple termination point and improve measurement accuracy.
5. What is the input range and accuracy of the FBM202?
The electrical input range is -10.5 to +69.5 mV DC, with 71.419 mV corresponding to the full 65,535-count range. For millivolt inputs, the specified accuracy is ±0.03% of span, equivalent to ±24 μV at 25°C. The module also provides a temperature coefficient of ±50 ppm/°C.
6. Does the FBM202 provide thermocouple burnout detection?
Yes. Each thermocouple/mV input channel provides thermocouple burnout detection with an upscale response. If an open-circuit condition occurs in a thermocouple circuit, the module can drive the input reading toward the upscale value, allowing the control system to identify a potential sensor or wiring fault.
7. How does the FBM202 communicate with the Foxboro control system?
The FBM202 communicates with its associated FCM or FCP through a redundant 2 Mbps module Fieldbus. The acquired thermocouple and millivolt data is converted and transferred to the control system for monitoring, alarming, trending, and process-control functions.
8. What should be checked when installing or commissioning the FBM202?
Verify the module model and order number, compatible baseplate and termination assembly, 24 V DC power supply, Fieldbus connections, and field wiring before commissioning. For thermocouple applications, also confirm the sensor type, polarity, extension or compensating cable, reference-junction configuration, and input-channel configuration. If a channel shows an abnormal value, checking the thermocouple wiring and termination assembly should be part of the initial troubleshooting process.
