EIB 700




EIB 741, EIB 742

Encoder inputs

D-sub connections, 15-pin, female (X11 to X14), for four encoders

Input signals (switchable)

1 VPP (11 µAPP upon request)

EnDat 2.1

EnDat 2.2

Voltage supply for encoders

5.12 V DC ± 0.15 V; max. 450 mA per channel

Overcurrent protection (automatic switch-off, resettable) at 550 mA

Input frequency

≤ 500 kHz

Subdivision factor


Signal adjustment

Automatic adjustment of offset, phase and amplitude

Cable length1)

≤ 150 m

≤ 150 m

≤ 100 m

Data register for measured values

48 bits (only 44 bits are used)

Interval counter

  • Derived from axis 1 (only 1 VPP),
  • Interpolation factor can be set from 1-fold to 100-fold
  • Can be used as trigger source or additional counting axis

Measured-value memory

Typically 250,000 position values per channel

Measured-value trigger2)

Storage of the measured values of the four axes alternatively through external or internal trigger.


• Signal via trigger input
• Software command (over Ethernet)


• Timer
• Interval counter
• Reference pulse of the respective axis (from axis 1 also possible for other axes)

Trigger input3)

D-sub connections, 9-pin, male; differential inputs as per RS-485 (terminating resistors can be activated)

Trigger output3)

D-sub connection, 9-pin, female, 4 differential inputs as per RS-485

Access to measured values

Depends on the selected operating mode (see separate table)


  • Driver software for Windows, Linux and LabVIEW
  • Program examples
  • EIB application software

Data interface

Ethernet as per IEEE 802.3 (max. 1 GB) (data cable must be suitable)

Network address

Automatic assignment through Dynamic Host Configuration Protocol (DHCP) or manual assignment

Operating temperature

0 °C to 45 °C (storage temperature –20 °C to 70 °C)

Power supply

EIB 741: 100 V to 240 V AC (± 10%), 50 Hz to 60 Hz (± 2 Hz), power consumption approx. 30 W

EIB 742: 24 V DC (-15 %/+20 %), ≤ 2 A

1) The supply voltage range of the encoder must be maintained; specified cable length applies when HEIDENHAIN cables are used.

2) Different trigger sources can be assigned to the individual axes.

3) Can also be used as logical input or output.
