Beckhoff EL2024 4-Channel 2 A Digital Output EtherCAT Terminal

EL2024 is an EL EtherCAT digital-output terminal rated 2 A per channel. Four 2 A outputs combine higher-current channels with direct two-wire actuator connections.

Beckhoff lists this exact model as Last Time Buy. Its EL wiring and process-image layout remain useful for an existing station. The manufacturer’s suggested ED alternative uses a different product identity and push-in connection technology; it is not this EL product.

The terminal electronics use the E-bus; the 24 V DC actuator circuit uses the station power contacts. 2-wire describes the terminal connection arrangement, not an Ethernet cable or an external connector supplied with the terminal.

Use the labeled supply and 0 V points in the exact terminal map. A physical position used for a supply or earth point on a two-channel terminal may be a signal point on a higher-density terminal.

The housing power contacts are rated to carry up to 10 A through the station segment. This does not increase a channel’s rated current or any model-specific total-current limit. Add the actuator loads and terminal consumption when dividing the station into protected power-feed segments.

The channel LEDs indicate output state. Electronic short-circuit protection does not add the controller-visible diagnostic process image of EL2014 or EL203x. Match the selected terminal’s process image in TwinCAT rather than treating the channel count as its complete interface.

Install the EL terminal in a compatible EtherCAT terminal station behind its coupler or controller and scan/configure the terminal in TwinCAT. The terminal communicates through the E-bus side contacts; it does not have its own RJ45 Ethernet port. Provide a station end terminal and the required power feeds as part of the station assembly.

The SyncManager watchdog monitors process-data communication. Configure the watchdog and output behavior for the machine before commissioning; disabling a watchdog to maintain outputs changes the communication-loss response. A standard EL digital-output terminal is not a TwinSAFE safety-output terminal.

Mount on a 35 mm DIN rail, engage the side slot/key connection and the rail lock, and preserve the E-bus and power-contact alignment. The EL terminal has a fixed spring wiring level operated by a screwdriver; ES is the separate pluggable-wiring version. Disconnect power before installing, removing or rewiring station terminals.

Use the operating-temperature range with the documented mounting conditions and load current. IP20 provides no weatherproof field enclosure. Space, ventilation, power-feed protection and the complete station’s current budget remain installation decisions, not features supplied by one output terminal.
