    Encoder inputs

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

    Interface (switchable)

    1 VPP ( 11 µAPP upon request)

    EnDat 2.1

    EnDat 2.2

    Voltage supply for encoders

    DC 5.12 V ±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)5),

    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.

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

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

    Trigger input3)

    D-sub connection, 9-pin, male

    Differential inputs as per RS-485, (terminating resistors can be activated)

    Trigger output3)

    D-sub connection, 9-pin, female

    4 differential outputs 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 interface4)

    Ethernet as per IEEE 802.3 (10/100/1000 Mbit/s)

    Network address

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


    ≈ 213 mm x 152 mm x 42 mm

    Operating temperature

    Storage temperature

    0 °C to 45 °C

    0 °C to 70 °C

    Voltage supply

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

    EIB 742: DC 24 V (-15 %/+20 %), max. 2 A

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

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

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

    4) The quality of the data cable between EIB and PC must be adapted to the transmission rate and cable length.

    5) Maximum input frequency during referencing 70 kHz

    Remark: The available functions can be expanded by updating the firmware.
