Product Description:

The high-precision Beckhoff model ELM3004-0000 from EtherCAT Terminal functions for industrial automation requirements.

The terminal contains four channels that deliver dependable signal processing for differential signals suitable for diverse measurement operations. Users can make quick and secure connections through the 2-wire connection technology secured by a push-in 2-pin service plug. During simultaneous data acquisition, the ELM3004-0000 collects signals at 100 µs/10 ksps per channel speed for all channels, enabling efficient acquisition. The device enables users to specify an oversampling factor between n = 1 and n = 100 and reach a maximum sampling rate of 10 ksamples/s, which can be adjusted based on application needs. The device exhibits internal resistance greater than 500 kΩ at 30 V and greater than 4 MΩ for other voltage levels, thus maintaining high input impedance and low signal interference. This device stands out for its measurement precision because it achieves readings with a typical error rate of less than ±50 ppm/±0.005%, which allows high-precision applications. The device maintains outstanding stability across different temperatures because its typical temperature coefficient stays below 1 ppm/K.

Connection diagnostics are available through the terminal aid users by detecting broken wires and short circuits, which enables them to solve possible system issues. This terminal enables multiple clocks to operate accurately at a precision level below 1 microsecond throughout the EtherCAT network. Measurement capabilities from the terminal reach high definition because it provides a 24-bit resolution that includes sign information. The ELM3004-0000 provides operation across harsh industrial conditions because its temperature range extends between -25°C and +60°C. This terminal carries a weight of 350 grams and delivers reliable operations for industrial use.
