The EP3048-0002 EtherCAT Box has 8 channels and processes 20 mA standard signals with 16-bit resolution and up to 2000 measured values per second. Each channel can be parameterized individually via the controller/TwinCAT; signals in the range of -20…+20 mA , 0…+20 mA and 4…+20 mA can be processed by each channel. The current inputs are designed as single-ended. With a technical measuring range of ±107 % of the nominal range, the module also supports commissioning with sensor values in the limit range and evaluation in accordance with NAMUR NE43. Two channels are connected via an M12 socket.
