    EIB 741

    EIB 742

    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 meas. values

    48 bits (only 44 bits are used)

    Interval counter

    Derived from axis 1 (only 1 VPP)4),

    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 and 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 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 interface5)

    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

    0 °C to 45 °C; (storage temperature 0 °C to 70 °C)

    Power supply

    EIB 741: AC 100 V to 240 V (±10 %), 50 Hz to 60 Hz (±2 %), power consumption up to 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) Maximum input frequency for referencing: 70 kHz

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