EIB 742 External Interface Box

November 13, 2013

HEIDENHAIN offers a new EIB 742 external interface box for precise position measurement. It is a network-capable measuring solution that removes the requirement of a PC interface card that is usually necessary when connecting measurement apparatus to an industrial PC or laptop.

The EIB 742 is ideal for inspection stations and multipoint inspection apparatuses under extreme vibration loads.A maximum of four HEIDENHAIN encoders, either with sinusoidal incremental signals (1Vpp) or with EnDat interfaces (EnDat 2.1 and EnDat 2.1), can be connected to the EIB 742. The 24 V DC is supplied by an operator's external power supply via a screw-on connection. The EIB 742 is certified to UL 61010-1 and CSA 61010-1 standards.

This external interface box subdivides the periods of the incremental signals up to 4096-fold for measured-value generation. The integrated measured-value memory enables the EIB 742 to save up to 250,000 measured values per axis. Internal or external triggers can be used for axis-specific storage of the measured values.

A standard Ethernet interface using TCP/IP or UDP communication is standard for data output.This permits the direct connection to the PC or laptop. The type of measured-value transfer can be selected through the operating mode (transfer of individual values, block transfer, or transfer upon software request).

Driver software for Windows, Linux and LabVIEW is included in the items supplied in order to process the measured values on the PC. The driver software facilitates programming as well as includes programming examples demonstrating the performance range of the EIB 742.

Thanks to its compact dimensions, two EIB 742 interface boxes fit next to each other within a standard 19-inch housing, occupying one height unit. Multiple boxes can also be daisy-chained in other configurations.
