Features:
- Absolute position: one standard SSI encoder channel enters the POINT I/O station
- Flexible framing: software selects data rate, word length, delay, and Gray or binary handling
- RS-422 signaling: differential clock and data pairs support distance-dependent cable runs
1734-SSI translates an absolute encoder’s serial position word into controller data instead of counting incremental A/B pulses.
Its communication rate and cable reach are directly related, making wiring distance an early selection constraint.
Word format, conversion, latching, comparators, and data-valid status determine how the controller should interpret each position update.
Availability of 1734-SSI is subject to Apter Power inventory and sourcing confirmation.

Define the position word
- Word length: set 2...31 bits for the encoder format.
- Code: choose Gray or binary and apply conversion only when required.
- Delay: match word timing to the sensor specification.
- Validity: monitor the data-invalid flag before using the produced position.
Balance rate, distance, and wiring
- Pairs: use shielded twisted pairs for D+/D- and C+/C-.
- Rate: select 125 kHz through 2 MHz in software.
- Reach: keep cable length within the rate-specific official limit.
- Sensor power: verify 10...28.8 V DC demand stays within 450 mA.
Supported product applications
- Rotary absolute encoders: acquire shaft position over standard SSI.
- Linear position sensors: bring absolute travel data into POINT I/O.
- Optical distance devices: interface supported MSB-aligned SSI measurements.
- Latched position tasks: capture or compare position words with the module’s documented functions.
