Information About EL3104

The BECKHOFF EL3104 is an advanced EtherCAT Terminal with four channels of differential analog input designed for voltage signals within a range of ±10 V. Operating with high precision at 16-bit resolution, it ensures accurate and reliable measurements for industrial automation.

Powered via the E-bus, this terminal utilizes differential input technology with a signal type of differential voltage, spanning -10 to +10 V. It supports distributed clocks with precision below 1 µs, providing synchronized data acquisition. The internal resistance is over 200 kΩ, and the input filter has a limit frequency of 5 kHz.

The EL3104 boasts a common-mode voltage of UCM max. 35 V relative to GND power contact, ensuring robust performance in various scenarios. With a quick conversion time of approximately 100 µs and a resolution of 16 bits (including sign), it delivers precise measurements.

Featuring electrical isolation up to 500 V between the E-bus and signal voltage, the terminal ensures safety. It has a typical E-bus current consumption of 130 mA and requires no address or configuration setting, streamlining integration.

Additional features include standard and compact process image support, switchable measuring data representation, activatable FIR/IIR filters, and limit value monitoring. Operating in a temperature range of -25 to +60 °C and providing robust EMC immunity and emission compliance, it is suitable for demanding industrial environments.

With approvals such as CE, UL, ATEX, IECEx, and cFMus, and constructed from polycarbonate, the EL3104 has dimensions of 12 mm x 100 mm x 68 mm. It can be installed on a 35 mm DIN rail according to EN 60715 with lock and supports side-by-side mounting through a double slot and key connection. The terminal ensures reliable and accurate analog input for a variety of industrial applications.
