EL2808 Beckhoff EtherCAT Terminal – 8-Channel Digital Output, 24 V DC, 0.5 A
The EL2808 connects binary 24 V DC control signals to actuators with full electrical isolation. It packs eight output channels into a 12 mm wide HD housing. Each channel drives ohmic, inductive, or lamp loads up to 0.5 A. The outputs are short-circuit proof and reverse polarity protected. Power contacts pass through for easy daisy-chaining. LEDs show signal state per channel. The terminal needs no address or configuration setting. It works with any EtherCAT network. Install on a 35 mm DIN rail. The EL2808 suits high-density panels where space matters.

Professional FAQ
Q: Can I use the EL2808 with inductive loads like relays or valves?
A: Yes. The terminal supports ohmic, inductive, and lamp loads. Each channel handles up to 0.5 A. For high-inductance loads, add a freewheeling diode to protect the output stage. This extends terminal life in harsh factory environments.
Q: Does the EL2808 need any address or configuration setting?
A: No. The terminal works without address or configuration settings. The EtherCAT master maps the 8 outputs automatically. This saves commissioning time. Just plug it into the network and power the 24 V DC contacts.
Q: How do I wire solid versus stranded conductors?
A: Solid wire goes in directly with the plug-in technique. For stranded wire, use a screwdriver to actuate the spring. Ferrules work from 0.14 to 0.75 mm². Strip length is 8 to 9 mm. This keeps wiring fast and tool-free for solid conductors.
Q: What approvals does the EL2808 carry for hazardous areas?
A: The terminal holds CE, UL, ATEX, and IECEx approvals. The ATEX marking is II 3 G Ex ec IIC T4 Gc. IECEx marking is Ex ec IIC T4 Gc. This makes it suitable for Zone 2 gas environments when installed correctly.
Q: Is the EL2808 a good spare part for older Beckhoff systems?
A: Yes. The EL2808 remains in regular delivery. It drops into existing EtherCAT networks. Oiltech Controls tests each unit before shipment. We also stock refurbished options for budget-focused projects. This helps keep obsolete lines running without redesign.
