FOC transmitter / decoder sets – SSI, HTL/TTL (up to 1 MHz)

Implement FOC transmission path (1 FOC cable) for very fast and dynamic control processes (absolute / incremental)

12-30 VDC

• Transmitter FO-TX-1:
  Incremental: 0°, 90°, N, STATUS; each with inverted signals
• Transmitter FO-TX-3:
  Absolute SSI: DATA, DATAG, STATUS
• Transmitter FO-TX-4:
  Absolute SSI: DATA, DATAG, STATUS
  Incremental: 0°, 90°, N, STATUS; each with inverted signals
• Signal level:
  Absolute SSI: RS 422
  Incremental (configurable via DIP switches): HTL differential, HTL single-ended, RS 422, TTL single-ended

• Decoder FO-DX-1:
  2 output blocks (selectable for each output block: HTL or TTL)
  Incremental: 0°, 90°, N, STATUS; each with inverted signals
• Decoder FO-DX-3:
  Absolute SSI: DATA, DATAG, STATUS, STATUSG
• Decoder FO-DX-4:
  Absolute SSI: DATA, DATAG, STATUS, STATUSG
  Incremental: 0°, 90°, N, STATUS; each with inverted signals
• Signal level:
  Absolute SSI: RS 422
  Incremental (selectable via a variety of module types): HTL differential, RS 422, TTL

Transmitter FO-TX:

• Incremental: max. 1 MHz (RS 422), 400 kHz (HTL, TTL)
• Absolute SSI (transmitter as master for SSI absolute encoder), preset ex works (adjustments on request): 3.67 MHz (CLK frequency), Timeout 2 µs, Resolution 13 bit (12-30 bit)

Decoder FO-DX-3 / FO-DX-4:

• Absolute SSI (controller as master for decoder), preset ex works: 2 MHz (CLK frequency), Timeout 20 µs, Resolution 13 bit (adjustments on request: 12-30 bit)

Electronic housing for standard mounting rails

25 x 122 x 117 mm

Terminal strips and FOC connector to outside of module

-20 °C to +70 °C

IP20 (switchboard installation)

• Constant signal processing time <1 µs (transmitter input to decoder output)
• Very high sampling rate; incremental signal jitter <15 ns
• Very high SSI clock frequencies >2 MHz in combination with SSI absolute encoders ASS(H) 40/60
• FOC range up to 1000 m
• Integrated cable break and status monitoring
• Option: additional electric isolation between the two output blocks via separate supply voltage (FO-DX-1i)
• Option: Installation housing (IP65 / IK10, temperature range: -35 °C to +65 °C)
