EL307x, EL4x7x: The new generation of multi-functional analog terminals
A new generation of Beckhoff analog I/Os
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 known standard signals in the range of ±10 V and ±20 mA can be output per channel – for example, 4…20 mA. The current outputs can also drive high burden resistors and report an overload or wire break or, in the case of a voltage output, a short circuit. The voltage and current 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.
