EP3184-0002 | 4-channel analog input ±10 V or 0/4…20 mA, parameterisable, single-ended, 16 bit

The EP3184 EtherCAT Box has four analog inputs which can be individually parameterised, so that they process signals either in the -10/0…+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 are single-ended 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.

The signals are optionally connected via 1 channel per M12 socket (EP3184-0002) or via 2 channels per M12 socket (EP3184-1002). In the 2-channel version socket 2 and 4 are not allocated.
