Foxboro PBCO-D8-010 FBM I/O cards

Foxboro PBCO-D8-010 FBM I/O cards

General description: 

The Termination Board (TB) model PBCO-D8-010 is designed to connect the D1000 Series Intrinsically Safe isolation and protection modules, directly to the Foxboro FBM I/O cards type FBM201, FBM237, FBM204 and FBM205 without the standard Field Termination Assembly normally needed to interface the backplane. 

The TB consists of D1000 Series modules mounted on backplane which carry Safe Area signals and supply. The range of modules includes different types to handle the majority of applications. 

The TB PBCO-D8-010 connector is pin to pin compatible with the standard system cable, thus avoiding the need of special cable or external wiring. 

The TB connectors link with the Provox I/O cards by standard Provox cable (see connection tables for details). 

The FBM201 is a 8 channels, 4-20 mA analog input board. The FBM237 is a 8 channels, 4-20 mA analog output board.

The FBM204 is a 4 channels 4-20 mA analog input plus 4 channels 4-20 mA analog output board.

The FBM205 is a 4 channels 4-20 mA analog input plus 4 channels 4-20 mA analog output board.

The TB is provided with two connectors to interface two FBM I/O cards.

The Intrinsic Safety protection and signal isolation is made through the D1000 Series Associated Apparatus. The modules type accepted are:

Analog Input D1010D, D1014D, D1052D, D1072D to interface FBM201;

Analog Output D1020D to interface FBM237;

Analog Input D1010D, D1014D, D1052D, D1072D plus Analog Output D1020D to interface FBM204 or FBM205. The TB can accept 16 input channels AI or AO, and can only be used for 2 channels modules.

The connections to/from the Hazardous Areas are made at the module terminal blocks, thus avoiding the TB Intrinsic Safety certifications, resulting in a quick design and cost effective solution.

The 24 Vdc power supply for the TB is connected to a two dual plug-in terminal blocks, this resulting in a redundant power supply and daisy chain connection also when terminal block is not inserted in the corresponding mating connector.

The power supply is then bussed to the isolator modules by the TB.
