Difference Between FBM214B and FBM216B

FBM214B

Working Mode: Single module non-redundant

Application: Ordinary non-critical process loops

Termination Assembly: RH924JH / P0924JH

FBM216B

Working Mode: Dual module hot redundant, automatic master/standby switch

Application: Important critical loops requiring no downtime

Support full system redundancy and hot-swap replacement

Key Features

Supports both conventional 4–20mA transmitters and HART smart instruments.

Independent HART modem per channel for remote configuration, calibration and diagnosis.

High galvanic isolation avoids ground loop interference and field noise.

Industrial G3 rugged design for long-term stable operation.

Both models support hot swap under corresponding system configuration.

Application

Suitable for pressure, flow, level, temperature HART instrument signal collection.

Widely used in chemical, petrochemical, power, oil & gas and water treatment DCS projects.
