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.
