EL4034 Beckhoff EtherCAT Terminal 4-Channel Analog Output EL4034

EL4034 Beckhoff EtherCAT Terminal | 4-Channel Analog Output, ±10 V, 12 Bit

The EL4034 is a 4-channel analog output terminal from the Beckhoff EtherCAT range. It outputs voltage signals from -10 V to +10 V with 12-bit resolution. Each channel is electrically isolated. The output stages run from a 24 V DC supply through the power contacts. All four channels share a common ground potential. LEDs show the signal state of each channel. This terminal suits drives, valves, analog meters, and positioners that need a stable bipolar voltage command.

FAQ

Q: How do I know the EL4034 is the right terminal for my drive?

A: Check the drive command input. If it needs -10 to +10 V, the EL4034 fits well. If it needs 0 to 10 V, a unipolar terminal is cheaper.

Q: Can I use the EL4034 in an ATEX area?

A: Yes, with the right panel design. The Ex marking is II 3 G Ex nA IIC T4 Gc. Follow local rules for Zone 2 use.

Q: Why choose the ES4034 over the EL4034?

A: The ES4034 adds pluggable wiring. That helps when you must swap a terminal fast without redoing every wire.

Q: What causes output error in real panels?

A: Long unshielded cables and ground loops add error. Use shielded twisted pair and keep signal wires away from drives.

Q: How do I check a used EL4034 before buying?

A: Ask for the LED test, channel-by-channel voltage check, and E-bus scan result. A good seller sends these before shipment.
