A readback feature is provided that detects failures of the output channel. In a repair situation, when a single module is replaced, the inputs and outputs are maintained by the redundant module. HART® signals are electrically compatible with the 4-20 mA signals, permitting the plant to upgrade field devices without the need to change the control system. The FBM208 provides the same functionality and is used to upgrade from the older FBM05.
