The complete control solution in hygienic design

The complete control solution in hygienic design

The EQ3174 EtherCAT Box has four analog inputs which can be individually parameterized, so that they process signals either in the -10…+10 V or the 0/4…20 mA range. The voltage or input current is digitized 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 parameterization purposes. The parameters are stored in the module.

The modules of the EQxxxx series are made of stainless steel in hygienic design. Therefore they are ideal for applications in the food, chemical or pharmaceutical industries, which require protection rating IP69K.
