Product Description:
The EL2022 is a Beckhoff digital output terminal in the EL EtherCAT Terminals series. It provides two 24 VDC switching channels that connect solenoids, contactors, or indicator lamps to an EtherCAT I/O network, allowing the controller to actuate loads directly through the system bus. The module clips onto a standard 35 mm rail alongside adjacent terminals, occupies minimal panel depth, and supports variable installation positions within the terminal string. Its compact format allows output channels to be added without requiring a separate remote I/O enclosure. Front-facing connection points keep field wiring accessible after the terminal has been installed in a control cabinet.
Each channel forwards the supply potential and supports a continuous load current of up to 2 A, while the common power rail operates at 24 VDC. The terminal draws up to 100 mA from the E-bus to power its internal logic and LED indicators. The semiconductor output stages turn on within 40 µs and turn off in approximately 200 µs, keeping switching delays low during rapid machine sequences. Two independent outputs appear to the controller as a two-bit process image, which simplifies address mapping and limits cyclic data traffic. Supported loads include resistive heaters, inductive coils, and filament lamps, allowing the channels to operate common industrial devices. Integrated short-circuit and reverse-voltage protection helps prevent damage to the terminal and connected bus segment when output wiring faults occur.
The housing has an IP20 protection rating and is intended for installation inside a suitable control cabinet. Each channel permits less than 1.7 J of inductive switch-off energy, helping control voltage generated when relays, solenoids, or brakes are released. The output terminals face the operator side, so conductors can be connected or inspected without removing neighboring modules. Internal power contacts distribute supply voltage between adjacent terminals without separate jumper wiring, while the slide-lock arrangement secures each module to the mounting rail. Status LEDs provide a visible indication of output activity and assist with checking channel operation from the front of the terminal assembly.
