Beckhoff EL4074 | EtherCAT Terminal, 4-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.

The EL4072 and EL4074 have 24 V/0 V contacts for the supply of the

actuators. With a technical output range of ±107% of the nominal range,

the channels can even transport unconventional setpoints, such as for error

reporting purposes.

Special features:

• combined output terminal: 10 V/20 mA

• 107% measurement/output range

• high output power at 20 mA: load up to 500 Ω

• 2 ksps conversion rate per channel for standard automation tasks

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