Foxboro FBM I/O cards PBCO-D8-009

Foxboro FBM I/O cards   PBCO-D8-009

General description:

The Termination Board (TB) model PBCO-D8-009 is designed to connect the

D1000 Series Intrinsically Safe isolation and protection modules, directly to the

Foxboro FBM I/O cards type FBM211. FBM207b, FBM241c and FBM242 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-D8-009 connector is pin to pin compatible with the standard system

cable, thus avoiding the need of special cable or external wiring.

The TB connector link with the Provox I/O cards by standard Provox cable

(see connection tables for details).

The FBM211 is a 16 channels, 4-20 mA analog input board.

The FBM207b is a 16 channels digital input board.

The FBM241c is a 8 channels digital input plus 8 channels digital output board.

The FBM242 is a 16 channels digital output board.

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 FBM211;

Digital Input D1030D, D1032D to interface FBM207b or FBM241c;

Digital Output D1049D to interface FBM241c or FBM242.

The TB can accept 16 input channels AI or 16 input channels DI or

8 channels DI + 8 channels DO or 16 output channels DO, 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.
