Product Description:
The EL3041-0000 is an analog input terminal from Beckhoff’s EL EtherCAT Terminals series. It connects voltage signals from field devices to an EtherCAT I/O system so a PLC can monitor process variables in real time. As a single-channel module, it saves rack space and relies on the EtherCAT E-bus to pass power and communication to adjacent terminals, allowing installation on a DIN rail without additional wiring. The terminal is intended for control cabinets that meet the IP20 protection class and is suited for machine automation where compact, modular signal acquisition is required. Its narrow form factor also makes it useful in stations where only one measurement point must be added without expanding to a larger I/O assembly.
This model provides 1 analog input referenced to a single-ended ground and offers 12-bit resolution for digitizing incoming signals. Power for its signal conditioning electronics is taken directly from the control network through the E-bus, eliminating a separate supply line and helping keep terminal assemblies compact. The housing meets the IP20 ingress rating, so it must be mounted in an enclosure. An internal low-pass network imposes a 1 kHz filter cutoff to attenuate high-frequency noise before the sample-and-hold stage. The terminal publishes 2 bytes of status and 2 bytes of value into the process image, does not support CoE storage, and does not implement distributed clocks, so time stamping is handled by the parent controller.
Converted values are packaged with a 16-bit data presentation for transmission on the fieldbus, which preserves gain and offset adjustments in a format wider than the converter itself. Isolation between the input channel and the logic side is rated for 30 V dielectric strength. Specified service temperatures span -25 °C to +60 °C, enabling use in refrigerated zones or warm machinery spaces without derating. Acquisition is based on simultaneous sampling, so each communication cycle delivers a coherent measurement value to the control system. This helps the terminal support stable process monitoring in compact EtherCAT I/O stations.
