SS RCD Data Sheet

Solid State Switching Card (SS RCD)

Reserve Controller Director Solid State Switch PWAs are direct replacements for existing electromechanical relay switch PWAs used in all Hiway Reserve Controller Directors (RCDs). This product represents another of Yamatake's steps in a continuing commitment to support the TDC 2000 through at least 2025.

Benefits of the Solid State Switching Cards

Aging electromechanical relay based switch PWAs are prone to stick in one position or may fail to switch. Accordingly, many sites do not perform the recommended preventive maintenance procedures and are therefore unsure if their Uninterrupted Automatic Control (UAC) systems are working properly. With the use of Solid State Switch PWAs, users of Data Hiway systems with RCDs can return their systems to their original control robustness while also receiving the following benefits:

      • - Reliability improved due to state of the art components and circuit design.
        • ➨ Virtually unlimited service life due to solid state relay design.
      • - Reduce power consumption up to 20%.
      • - Simple board for board replacement.
      • - Coexistence and interoperability with original electromechanical designs

Replacement Details

The 16 solid state switch PWA (80603812-001) is mounted in chassis slot 9 in both Basic and Extended Controller RCDs and in slot 10 in the MC RCD. The 12 solid state switch PWA (80603812-002) is mounted in chassis slots 10 through 12 in both Basic and Extended Controller RCDs and in slots 11 through 13 in the MC RCD.

Both solid state switch types can co-exist with existing electromechanical relay based switch PWAs. However, due to the age and failure modes of the existing switches it is recommended that all existing switch PWAs in an RCD be replaced to insure system robustness.
