FOXBORO FBM239

The FBM239 contains 16 discrete input and 16 discrete output channels that are compatible with voltages and currents commonly found in industrial plants. An external power supply is used to energize the field circuits.

The FBM239 Discrete 16DI/16DO Module provides 16 digital inputs with sixteen digital output channels. Associated Termination Assemblies (TAs) and Termination Assembly Adapters (TAAs) provide for discrete nominal inputs of 30 V dc, 60 V dc, 120 V ac/125 V dc or 240 V ac and nominal outputs of 60 V dc, 120 V ac/125 V dc or 240 V ac. The module performs signal conversion required to interface the electrical input signals from the field sensors to the Module Fieldbus.

Depending on the type of I/O signal required, the TAs or TAAs support current limiting devices, high voltage attenuation circuits, optical isolation and external power source connections. When connected to the appropriate Termination Assembly Adapters (TAAs) or TAs, the FBM239 module provides functionality formerly provided by the 100 Series FBM I/O subsystem. TAAs and TAs are available which support the functionality of the main FBM09, FBM10, FBM11, FBM26 and FBM41 (8 input/ 8 output main FBMs). These main FBMs may be used with expansion FBM14, FBM15, FBM16, FBM27 or FBM42 (8 input/8/output expansion FBMs).
