EP3182-1002 | 2-channel analog input ±10 V or 0/4…20 mA, parameterisable, single-ended, 16 bit, 2 digital control outputs, 24 V DC, short-circuit-proof

The EP3182 EtherCAT Box has two analog inputs which can be individually parameterised, so that they process signals either in the -10/0 to +10 V or the 0/4 to 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 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.

In addition, the EP3182 has two digital outputs to connect binary control signals from the controller to the actuators at the process level. These two outputs (sink/source type) are intended to switch logic inputs or outputs with a minimum impedance of 10 kΩ (e.g. reset inputs of digital sensors). They handle load currents of up to 2 mA, are short-circuit proof and indicate their status through light emitting diodes.

The signals are connected via the two M12 connectors.
