4-34 GenERAL Interface Description The interfaces specified herein are applicable to the OGS Rack components. The Rack Components will have a combination of power, data, thermal coolant, feed and waste water, environmental, cabin atmosphere, and the structural/mechanical interfaces.
A functional interface diagram between the OGS Rack and the Node 3 is defined in SSP 50316, Oxygen Generation System Rack to Node 3 Interface Control Document, Figure 3.1.1.1-1, Oxygen Generation System Rack to Node 3 Functional Interface Diagram.
SSP 57007, ISPR Structural Integrator’s Handbook, provides the structural information needed for physical integration of a Payload into an International Standard Payload Rack (ISPR). Mechanically, functionally and pragmatically, the Environmental Control and Life Support System (ECLSS) Equipment Rack is structurally identical to an ISPR.
The Rack Components are comprised of Marshall Space Flight Center (MSFC), Johnson Space Center (JSC), Hamilton Sundstrand Space Systems International (HSSSI), International Space Station (ISS) Program (both Government Furnished Equipment (GFE) and Contractor Furnished Equipment (CFE)) hardware and software. The component interfaces are defined in the subsequent paragraphs.
Oxygen Generation System Description The OGS assembly consists of the following components:
a. Rack Interface Panel (RIP)
b. CO2 Reduction Assembly (CRA) (scar)
c. CRA Scar Connector Panel
d. Power Supply Module (PSM)
e. Remote Power Controller Module (RPCM)
f. Avionics Air Assembly (AAA)
g. Rack Power Switch (RPS)
h. Area Smoke Detector (ASD)
i. Bracket Assembly/Coldplates and mounting
j. Oxygen Generation Assembly (OGA)
k. OGS Coolant Manifold
l. ECLSS Equipment Rack The OGS is fully compatible with the ISPR attachment mechanisms and envelopes. A functional diagram of the OGS is depicted in MSFC Drawing 97M11796, “OGS Rack System Schematic”.
OGS Interface Responsibilities Responsibility for the OGS Unless otherwise noted herein, Marshall Space Flight Center (MSFC), under agreement with the ISS Program Office, has the responsibility for designing the OGS Rack to the interface herein.
Interfaces All defined interface characteristics in the subsequent paragraphs which are identified as failure conditions represent the extreme value(s) for the associated characteristic (i.e. that interface will never experience a higher/lower value for that characteristic). For all other defined interface characteristics, the extreme value(s) represent the normal operating range for the associated characteristic (i.e. no OGS rack component will ever be required to operate when any of its interface characteristics are outside of its specified range).
Rack Interface Panel The OGS design will incorporate provisions for a rack interface panel as shown in SSP 50316, figures 3.2.1.3-1 and 3.2.1.3-2 for connection of utilities between the OGS Rack and Rack components. The RIP connectors are as defined in SSP 50316. Table I - RIP Electrical Connector Responsibility and Table II - RIP Fluid Connector Responsibility define responsibility for each connector.

CO2 Reduction Assembly Interface (Scar) CRA Description The CRA contains a CO2 compressor and a Sabatier reactor. The Carbon Dioxide Removal Assembly (CDRA) removes CO2 from the air and plumbs it to the Node 3 or US Lab standoff. This CO2 is drawn into the CRA by its CO2 compressor, compressed, and sent out of the CRA to a CO2 storage tank that is resident in the OGS rack. The compressed CO2 is drawn back into the CRA in a cyclic mode when waste H2 is available from the OGA for reacting. These gases are fed into the Sabatier reactor where they are combined to form methane and water vapor. The water vapor is condensed, separated and routed to the Water Recovery System (WRS) for processing (i.e. conversion to potable water) and the methane (along with some unreacted CO2 and H2 and remaining water vapor) will be vented to space. The functional interface diagram for the CRA is shown in Figure 1 - CRA Functional Interface Diagram.
Figure 1 CRA Functional Interface Diagram
CRA Interface Responsibilities Responsibility for CRA Unless otherwise noted herein, HSSSI has the responsibility for designing the CRA to the interfaces defined herein.
Responsibility For Interconnect Cabling/Tubing/Connectors MSFC will be responsible for providing interconnecting cabling between the OGS and CRA and between the OGA and CRA. MSFC will also be responsible for providing interconnecting tubing between the OGS and the CRA and between the CO2 Accumulator and the CRA. HSSSI will be responsible for providing the hydrogen interconnecting tubing between the OGA and CRA, the rack mounting structure/hardware/brackets for the CRA, and air ducting between the CRA and the OGS AAA. HSSSI is responsible for any changes to existing OGS hardware that may be required in order to operate the CRA in the OGS Rack.
CRA Interface Definition CRA Envelope Description The volume reserved for the CRA is defined in Figure 2 - CRA Mounting Envelope. Volume available for CRA use outside that defined in Figure 2 is defined by the integrated OGS Rack drawing package. The integrated rack Computer-Aided Design (CAD) model, which is not under Configuration Management control, will be provided for reference only. Routing of any ducting for air flow shall be in available volume in the rack.
Electrical Interfaces The CRA electrical connectors will be functionally equivalent to connector part numbers defined in Table XXV - CRA Scar Connector Panel Power Connector J31 Pin Assignments, Table XXVI - CRA Scar Connector Panel 1553B Data Connector J32 Pin Assignments, and Table XXVIII - CRA Scar Connector Panel Discrete Data Connector J34 Pin Assignments.

Electrical Interfaces Connectors Electrical Power Connectors The RPCM receives power from the rack interface panel through Bay J1B of the J1 connector and subsequently distributes power to the following components:
a. OGA Process Controller
b. CRA
c. ASD
d. AAA
e. PSM
f. DELETE The RPCM power connector pin assignments are shown in Table VIII - RPCM Power In Bay J1B and Table IX - RPCM Power Out Bay J1A.
Data Connectors The RPCM receives 1553B telemetry from a Multiplexer/Demultiplexer (MDM) external to the rack via the RIP. The 1553B interface will be on Bay J1C of connector J1. Internal to the rack, the 1553B bus cables will be less than 10 feet in length. The pin assignments for the 1553B interface are shown in Table X - RPCM Control/Data Connector J1C.
