ELM2744-0000 | EtherCAT Terminal, 4-channel solid state relay output, multiplexer, 48 V AC/DC, 1 A, potential-free, 1 x 4

With the ELM2744 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 ELM2744 is equipped with non-wearing solid-state relays (semiconductor switches) as switching elements, which are specially designed for small analog signals and thus set themselves apart from normal solid-state terminals like the EL279x. Due to the extremely low leakage current in the nA range in the opened state, the parallel-connected signals hardly influence each other at all. The multi-channel recording of analog signals as well as the flexible switching of various test states in production-integrated test stations is thus simple to achieve without externally connected switches.
