Beckhoff ELM2644-0000 | EtherCAT Terminal, 4-channel reed output, multiplexer, 48 V AC/DC, 0.5 A, potential-free, 1 x 4

With the EL/ELM264x (Reed) and ELM274x (Solid-State) Beckhoff

is considerably extending the usage possibilities of the integrated

measurement technology of the ELM3xxx series as well as the

normal EL3xxx/EL4xxx analog inputs and outputs, because several

sensors or sources can now be connected at the same time to one

analog input channel.

To this end, the ELM2642 and ELM2644 are equipped with Reed

relays as switching elements, allowing fast switching cycles and

a long lifetime. The electrical isolation and the constant contact

resistance of the reed switch allows the measurement of even

sensitive signals up to fast scanning operation.

Due to the double input connectors X the channels can easily be

connected to 1 x 8 multiplexers and more.

The multi-channel recording of analog signals as well as the flexible

switching of various test states in production-integrated test

stations is easily possible through the integration of the often

necessary switches into the EtherCAT system.
