Beckhoff EL4078 | EtherCAT Terminal, 8-channel analog output, multi-function

The EL4072. EL4074. and EL4078 analog output terminals output 10 V/20 mA

standard signals with 16-bit resolution and up to 2000 values per second.

Each channel can be parameterized individually via the controller/TwinCAT.

All common standard signals in the range of ±10 V and ±20 mA can be output

per channel – for example, 0…10 V and 4…20 mA. Each channel signals a short

circuit for voltage output or a wire break for current output. The current outputs

can also drive high burden resistors.

The outputs are designed as single-ended, which means that one connection

point of each channel is already connected in the terminal to +24 V or GND

and no longer needs to be wired separately.

Special features:

• combined output terminal: 10 V/20 mA

• 107% measurement/output range

• high output power at 20 mA: load up to 300 Ω

• 2 ksps conversion rate per channel for standard automation tasks

• output diagnosis (short circuit at voltage output, wire break at current output)
