Description for BECKHOFF EL2595-Channel LED Constant Current Terminal
The EL2595 EtherCAT Terminal contains a constant current source for LEDs and is designed for controlling one or several LEDs connected in series. The user specifies the required set current, the integrated power supply unit then provides the required forward voltage, depending on the connected LEDs. To this end, the EL2595 features a step up/step down power supply unit, which generates the output voltage from the 24 V DC input voltage. The output voltage is also adjusted during operation in order to maintain the set current. The current can be switched quickly for short-term lighting, so that the shortest light flashes are possible. The pulse duration can be set from 1 µs to infinite, the flash timing itself can be specified via timestamps with distributed clocks as in the EL2252. An external trigger input is also available. Extensive real-time diagnostic functions for input current/voltage and output current/voltage enable detailed control of the LED light intensity. If a specifiable load corridor is exited, e.g. due to load errors, the EL2595 switches off to protect the load (resettable).Technical dataEL2595Recommended useconstant lighting > 300 mA and simple illumination tasksConnection technology2-wireNumber of outputs1Input voltage24 V DC (-15 %/+20 %)Load typeohmic (LED)Distributed clocksyesDistributed clock precision<< 1 µsOutput voltage2…48 V DCMax. output current300…700 mA (depending on output voltage and Duty Cycle)Switching timestyp.
