Description
Configured for tachometer signal scaling in ABB DCS400, DCS500, and DCS800 DC drive systems, the ABB RASI-01 REV.H (base model RASI-01 Analog Speed Interface) provides direct electrical interfacing between high-voltage DC tachogenerators and low-voltage drive control electronics.

Backplane Bus Communication Velocity Licences
The RASI-01 REV.H interfaces strictly through the drive’s internal backplane bus operating at fixed deterministic cycle rates defined by the DCS system firmware. Firmware flash compatibility must be verified before installation; mismatched firmware may result in incorrect speed scaling or loss of tachometer feedback. Licensing restrictions apply to certain high-speed feedback configurations in DCS800 platforms, requiring activation of specific software options to exceed default scaling limits.
Frequently Asked Questions
Q: Can the RASI-01 REV.H be hot-swapped?
A: No. Power must be removed from the drive before installing or removing the module to prevent damage to the backplane interface circuitry.
Q: Is REV.H electrically interchangeable with REV.E?
A: Yes, provided all DIP switch and jumper settings are duplicated exactly; failure to match configuration will cause incorrect speed readings.
Q: What is the recommended torque for mounting screws?
A: Use standard M3 screws torqued to 0.5 Nm to avoid mechanical stress on the PCB.
Field Installation Guidelines
Install the module directly onto the designated SDCS-CON-x connector or via shielded ribbon cable routed away from high-current power wiring. Ground the tachometer shield at one end only, preferably at the drive chassis, to prevent ground loops. Verify DIP switch positions before energizing the drive. Inspect connector contacts for oxidation if the module has been stored for extended periods.
