EP3184-0002

EP3184-0002 is a Beckhoff module in the EP Digital Input Modules series. It provides four single-ended analog inputs for measuring signals relative to a common reference. The supported signal ranges are ±10 V, 0 to 10 V, 0 to 20 mA, and 4 to 20 mA, allowing the module to accept common voltage and current signals. Four 5-pin M12 sockets provide the analog input connections. The voltage inputs have a minimum resistance of 200 kΩ, which limits loading on connected signal sources.

The module converts inputs at approximately 100 µs per reading. Its 16-bit digital resolution includes the sign bit, enabling representation of positive and negative measurements. A 5 kHz filter limit frequency reduces signal content above the input bandwidth. Measurement uncertainty is no more than 0.3% of full scale, indicating the maximum measurement deviation across the selected range. The inputs are isolated to 500 V, providing electrical separation from other circuits.

The nominal US supply is 24 VDC with a tolerance of -15% to +20%. The UP voltage range is 0 to 30 VDC, and the sensor supply also supports 0 to 30 VDC for connected field devices. The unit operates from -25 to +60ºC. Its IP65, IP66, and IP67 protection ratings provide resistance to dust, water jets, and temporary immersion under the applicable rating conditions. The enclosure measures 30 mm in width, 126 mm in height, and 26.5 mm in depth.
