About the IS215ISBBH1A

The IS215ISBBH1A is a component created by GE for the Mark VI or the Mark VIe.  These systems were created by General Electric to manage steam and gas turbines.  However, the Mark VI does this through central management, using a Central Control module with either a 13- or 21-slot card rack connected to termination boards that bring in data from around the system, while the Mark VIe does this in a distributed manner (DCS--distributed control system) via control nodes placed throughout the system that follows central management direction.  Both systems have been created to work with integrated software like the CIMPLICITY graphics platform.

The IS215ISBBH1A functions as a GE ISBB Bypass module.  This component is contained within a rectangular housing with four inputs or outputs.  Two of these are placed on the bottom of the unit and two on the top. On the top of the unit, there are two female jacks placed side-by-side.  One of these (P2) is labeled ‘Transmit Out.’ The other (P3) is labeled ‘Receive In.’ The bottom of the unit has an additional female jack (P1) labeled ‘Full Duplex,’ and a two-position terminal strip (TB1) labeled 10 mA Max 24 V Dc.   Both the top and the bottom of the unit include openings to allow for the circulation of air and heat dissipation.

The front of the IS215ISBBH1A  has two LED status indicators. These are labeled Receiver Active and Not Bypassed.  The back of the unit is designed to give the user mounting options. The side of the unit includes labels for each of the module connectors (top and bottom,) and also has a chart to help diagnose issues with the front panel LEDs.
