- Synchronous Serial Interface (SSI) — The 1734-SSIK is an SSI master module reading absolute position from SSI-compatible encoders. Supports Gray and binary data formats, programmable data length, and selectable clock frequencies.
- Cable Length & Noise Handling — Use shielded twisted-pair cable for the SSI clock and data pairs. Max cable length is a function of the selected clock frequency; consult 1734-UM013 SSI Module User Manual for the derating chart.
- Configuration — Bits per frame, clock frequency, error bits, and parity are all configurable via Studio 5000 AOP. Save the tested configuration to the controller so ADR can restore it on module replacement.
- Module Current Budget — Draws 110 mA of PointBus current — include in the adapter power budget.
