Product Description:

The Beckhoff EL4004-0000 is the unit of output which consists of 4 channels which comes from the EL EtherCAT Terminal Series. It provides a high USB 2.0 voltage control output which measures 0-10 V range and thus suitable for volt-imprecise systems. The terminal has an accuracy of 12 bits which makes him ideal for typical applications that require reliable voltage outputs.

The terminal works on a supply voltage of 24 V DC and draws 40mA from contacts and 140mA from E-Bus respectively. Each output can drive loads of more than 5 kilohm and in case of short circuit protection is available to ensure that the system operates safely and risk of any kind is eliminated. The output error is reported to be less than 0.1% with self-explanatory VCC output levels which are in relation to the set point. The cut out time of approximately 250 microseconds which gives a quick response in real time control applications.

The EL4004-0000 works hand in hand with Distributed Clocks without noticeable delay so there is no problem along the EtherCAT interface. This is particularly important for processes which are dependent on timing, where it is crucial to produce outputs simultaneously on several devices. Another added advantage allows enhancing output safety where a person can define some outputs and make a hot swap or start ramp in case of some communication disruption. Five bolts hold the interconnect in place after the fixing block serves as a backup, weighing 85 grams and operating between -25 and 60 °C with a storage temperature of -40 °C. It also provides 4 x 16 bit analog output channels enabling straightforward implementation in EtherCAT systems.
