Foxboro FBM214b RH927AH HART Communication Input Module

FAQ

Q1: What is the Foxboro FBM214b RH927AH used for?
A: The FBM214b RH927AH is used to interface 4–20 mA field transmitters with a Foxboro DCS while also providing two-way HART digital communication with compatible field devices.

Q2: How many input channels does the FBM214b provide?
A: It provides 8 individually isolated input channels. Each channel can handle a standard 4–20 mA signal or a 4–20 mA signal with HART communication.

Q3: Does the FBM214b support HART communication?
A: Yes. The module has a dedicated FSK modem for each input channel and supports HART Version 5, 6, and 7 compliant instruments.

Q4: Can standard 4–20 mA transmitters be connected to the FBM214b?
A: Yes. The module supports both conventional 4–20 mA instruments and HART-enabled transmitters, so the eight channels can be used in different combinations.

Q5: Are the eight input channels electrically isolated?
A: Yes. Each input channel is galvanically isolated from the other channels, ground, and the module logic. This helps reduce interference between field circuits.

Q6: What is the accuracy of the FBM214b analog input?
A: The specified accuracy is ±0.03% of full scale, including nonlinearity. The module uses sigma-delta conversion for the analog input channels.

Q7: What are the dimensions and weight of the FBM214b?
A: The module measures approximately 102 mm high × 45 mm wide × 104 mm deep, with a height of approximately 114 mm including the mounting lugs. The module weighs approximately 284 g.

Q8: What type of mounting system is used with the RH927AH?
A: The FBM214b mounts on a modular baseplate. The RH927AH baseplate can be installed on a DIN rail, either horizontally or vertically, or mounted horizontally in a 19-inch rack with the appropriate mounting kit.
