EP3174-0002 | 4-channel analog input ±10 V or 0/4…20 mA, parameterisable, differential input, 16 bit

The EP3174 EtherCAT Box has four analog inputs which can be individually parameterised, so that they process signals either in the -10…+10 V or the 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 four input channels have differential inputs and possess a common, internal ground potential. 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.
