Beckhoff ELM3002-0000 EtherCAT Measurement Terminal, 2-Ch Voltage, 24-Bit

The Beckhoff ELM3002-0000 is a high-precision EtherCAT measurement terminal with 2 differential voltage inputs, selectable across 11 ranges from plus or minus 20 mV to plus or minus 30 V.

It samples at up to 20,000 samples per second per channel simultaneously at 24-bit resolution, with typical measuring error below 50 ppm and a temperature coefficient below 1 ppm/K, plus broken wire and short-circuit detection. Built-in functions include TrueRMS, PeakHold, integrator/differentiator and free numeric filters. It has a zinc die-cast housing with push-in service plugs, 707 VDC channel-to-bus isolation and distributed clocks.
