3.2.4 RSTi Expansion I/O Module
Apollo is especially suited for complex Surface Pumping System (SPS) applications. Many SPS
systems include Resistance Temperature Detectors (RTDs) to monitor several locations within
the motor and thrust chamber. To fulfill this requirement, the Apollo system supports the BH
Intelligent Platforms RSTi Expansion I/O modules. Current support is limited to up to 16 RTD
inputs using the 4 and 8 input RTD Modules shown in Table 10: RSTi Expansion I/O Module,
page 34. The system can use any combination of these two modules limited to 16 inputs.
RSTi I/O Components include:
