EL2008

EL2008 is a Beckhoff terminal in the EL EtherCAT Terminals series. It provides eight outputs with an 8-bit output process image, assigning one control bit to each channel. The nominal output voltage is 24 VDC, and each channel supplies up to 0.5 A for switching connected devices. It supports ohmic, inductive, and lamp loads, allowing it to control resistive equipment, coils, and lighting loads. The outputs are non-reactive, which prevents their switching states from affecting bus communication.

The terminal has a typical turn-on time of 60 µs and a typical turn-off time of 300 µs, indicating how quickly each output changes state. Each channel can dissipate 150 mJ of switch-off energy when disconnecting inductive loads. Reverse-polarity protection helps protect the terminal if the supply polarity is connected incorrectly.

The EL2008 typically draws 110 mA from the E-bus for terminal electronics and 15 mA through the power contacts. It mounts on a standard 35 mm DIN rail for installation in an electrical cabinet. Its IP20 protection class guards against contact with fingers and similarly sized solid objects but does not provide water protection.
