FO-TX-4 / FO-DX-4

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

  • Module set (transmitter FO-TX-4 + decoder FO-DX-4) for absolute values (SSI) and incremental signals (HTL or TTL)
  • Extremely fast and highly precise FOC signal transmission up to 1000 m (patent pending)
  • Designed for highly dynamic control of drives, including motor commutation
  • Just one fiber optic cable carries all data, integrated monitoring

Description

Fiber optics transmitter / decoder set

Comprising the FOC transmitter FO-TX-4 and the FOC decoder FO-DX-4, the innovative module set operates extreme quickly, highly precise and completely interference-free. It transmits incremental signals (HTL or TTL) as well as absolute values (SSI). These high-performance FOC modules always prove their value as powerful team players when high frequencies are demanded of the SSI encoder to ensure reliable and robust drive control, for example, motor commutation in mining or steel industry applications. In combination with the SSI absolute encoders ASS(H) 40 or ASSH 60 (equipped with an additional incremental output), the FOC modules FO-TX-4 and FO-DX-4 also guarantee interference-free and fast signal transmissions in those environments up to 1000 m, even at clock frequencies >2 MHz. All data is transmitted along one fiber optic cable, whose performance is monitored continuously by means of integrated cable break and status monitoring.

More About The FO-TX-4 / FO-DX-4 Transmitter Decoder Set In Australia

The FO-TX-4 / FO-DX-4 Transmitter Decoder Set offered by Hubner Australia is a highly precise and fast operating module set for incremental signals. It comprises the FOC transmitter FO-TX-4 and the FOC decoder FO-DX-4, which work together to provide interference-free fibre optic communication. The set is suitable for use in dynamic drive controls and is designed to operate at high speeds of up to 1 MHz. The decoder provides absolute SSI (controller as master for decoder) with a preset of 2 MHz (CLK frequency), Timeout 20 µs, and Resolution 13 bit. This module set is an innovative and reliable solution for electro-optical, SSI, and digital applications.

What are the features of the FO-TX-4 / FO-DX-4 Transmitter Decoder Set?

The FO-TX-4 / FO-DX-4 Transmitter Decoder Set is a module set that comprises the FOC transmitter FO-TX-4 and the FOC decoder FO-DX-4, designed for highly dynamic control of drives, including motor commutation. The set operates extremely quickly, highly precisely, and completely interference-free. It is suitable for transmitting incremental signals (HTL or TTL) and/or absolute values (SSI).

The modules are powerful team players when high frequencies are demanded of the SSI encoder to ensure reliable and robust drive control. The FO-TX-4 / FO-DX-4 Transmitter Decoder Set is designed to transmit signals via just one fibre optic cable, whose performance is exceptional. The decoder provides absolute SSI (controller as master for decoder) with a preset of 2 MHz (CLK frequency), Timeout 20 µs, and Resolution 13 bit.

The transmitter and decoder are housed in an electronic housing for standard mounting rails, with dimensions of 25 x 122 x 117 mm. The FO-TX-4 / FO-DX-4 Transmitter Decoder Set is an innovative, reliable, and high-performance solution for electro-optical, SSI, and digital applications.

What is the difference between FO-TX-4 / FO-DX-4 and FO-TX-1 / FO-DX-1(i) Transmitter Decoder Set

The FO-TX-4 / FO-DX-4 and FO-TX-1 / FO-DX-1(i) Transmitter Decoder Sets are both FOC module sets used for transmitting incremental signals, but they differ in the following ways: 

FO-TX-4 / FO-DX-4 Transmitter Decoder Set:

  • Comprises the FOC transmitter FO-TX-4 and the FOC decoder FO-DX-4.
  • Transmits incremental signals (HTL or TTL) as well as absolute values (SSI).
  • Operates extremely quickly, highly precisely, and completely interference-free.
  • Suitable for highly dynamic control of drives, including motor commutation.
  • Operates at a frequency range of up to 1 MHz.
  • The decoder provides absolute SSI (controller as master for decoder) with a preset of 2 MHz (CLK frequency), Timeout 20 µs, and Resolution 13 bit.
  • Housed in an electronic housing for standard mounting rails, with dimensions of 25 x 122 x 117 mm.

FO-TX-1 / FO-DX-1(i) Transmitter Decoder Set:

  • Comprises the FO-TX-1 FOC transmitter and the FO-DX-1 FOC decoder.
  • Transmits incremental signals (HTL or TTL).
  • Operates extremely quickly, precisely, and with no interference whatsoever.
  • Suitable for transmitting incremental signals via just one fibre optic cable.
  • Operates at a frequency range of up to 1 MHz for RS 422, 400 kHz (HTL, TTL).
  • The decoder is equipped with two output blocks, optionally with electrically isolated outputs.
  • Housed in an electronic housing for standard mounting rails, with dimensions of 25 x 122 x 117 mm.

Overall, the FO-TX-4 / FO-DX-4 Transmitter Decoder Set is a more advanced and versatile module set suitable for transmitting both incremental signals and absolute values and is designed for highly dynamic control of drives.

The FO-TX-1 / FO-DX-1(i) Transmitter Decoder Set, on the other hand, is a more basic module set suitable only for transmitting incremental signals via just one fibre optic cable.
