EP3162-0002 | 2-channel analog input ±10 V or ±20 mA, with galvanic isolation, single-ended, 16 bit

The EP3162 EtherCAT Box has two analog inputs which can be individually parameterised, so that they process signals either in the -10/0…+10 V or the -20/0/4…+20 mA range. The voltage or input current is digitised with a resolution of 16 bits, and is transmitted (electrically isolated) to the higher-level automation device. The two input channels are galvanically isolated. The input filter and therefore the conversion times are configurable in a wide range. If required, the inputs can be scaled differently, and automatic limit monitoring is also available. EtherCAT is used for parameterisation purposes. The parameters are stored in the module.
