EL2889 Beckhoff Digital Output Terminal 16 Channel
The EL2889 is a 16-channel digital output terminal from Beckhoff. It switches binary 24 V DC control signals to actuators. The terminal uses electrical isolation. LEDs show each channel state. It suits single-ended inputs. All loads must share the same reference point as the EL2889. Power contacts pass through. Outputs get supply from the 0 V DC power contact. This design saves cabinet space.

FAQ
Q: Can the EL2889 drive inductive loads?
A: Yes. It supports ohmic, inductive, and lamp loads. Each channel handles up to 0.5 A.
Q: Do I need to set an address for the EL2889?
A: No. The terminal needs no address or configuration setting. It works after wiring and power-up.
Q: What wire sizes fit the EL2889?
A: Solid wire: 0.08…1.5 mm². Stranded: 0.25…1.5 mm². Ferrule: 0.14…0.75 mm². Strip length is 8…9 mm.
Q: How do I choose between the EL2889 and a relay output terminal?
A: Choose the EL2889 for fast 24 V DC switching and compact 16-channel density. Choose relay outputs for AC loads or higher isolation needs.
Q: What should I check before ordering a used EL2889?
A: Confirm channel count, load type, and ATEX needs. Ask for test records. Check warranty and dispatch time. Oiltech Controls tests units before shipment.
