Internal Product Review
The EL3042-0017 is a Beckhoff analog input EtherCAT terminal with 2 analog inputs and 12-bit resolution. Single-ended signaling with a 0 V power contact reference keeps wiring practical and measurement behavior consistent in control applications. IP20 protection makes this terminal a solid fit for clean cabinet installations.

Product Description:
The EL3042-0017 is an analog input terminal produced by Beckhoff within the EL EtherCAT Terminals series. It clicks into the modular EtherCAT stack to capture low-level process voltages and stream the resulting data words to a controller across the backplane. Used in distributed automation panels, the terminal enables PLCs to monitor sensors such as transducers or potentiometric devices while keeping signal wiring short and shielded inside the cabinet.
The EL3042-0017 provides 2 analog input channels, each converted by a successive-approximation ADC that delivers a 12-bit resolution, giving a nominal step size of 0.024% of full scale. The digitized sample is right-justified within a 16-bit presentation width, so host software can assemble uniform words from mixed Beckhoff terminals. To suppress high-frequency interference, an internal RC network imposes a 1 kHz input filter cutoff. The front end withstands voltages up to 30 V, protecting it against accidental connection to adjacent 24 V power loops. Multiplex sampling alternates between the two channels, and the terminal forwards the 2-byte status field and 2-byte value field for each channel during every EtherCAT cycle.
The housing carries an IP20 protection rating, so the terminal must be installed inside an enclosure. Logic and interface power are supplied via the E-Bus, eliminating separate 24 V field wiring and allowing the reference potential to follow the common 0 V power contact on the carrier. The molded foot locks onto a 35 mm DIN rail for secure installation in densely populated rows. Signal inputs share a single-ended ground reference, which simplifies field cable selection when sensors already relate their outputs to the control cabinet ground. Distributed clocks are not supported, so timestamping must occur in an upstream master.
