Exact current control and synchronization of LED lamps. The LED strobe control terminals supply an LED with the desired current and voltage. Applications from continuous light to short light pulses in the kHz range are thus possible. Extensive real-time diagnostic, e.g., for input current/voltage and output current/voltage allow detailed monitoring of the LED light intensity. Overdrive applications are also possible with short high-current pulses through the LED.
In this 30-minute webinar, Sina Sampl, Product Manager I/O, begins with a brief introduction to LED technology before describing the functions of the different LED terminals. In addition, the EL2596-00x0 and EL2595 terminals are compared with each other and the functionality of the EL2595-00x0 described in greater detail. The parameterization and the functionality are then illustrated on the basis of a short practical example. In addition, the product manager presents an overview of the control of LEDs with digital output terminals from Beckhoff.

EL2595 | EtherCAT Terminal, 1-channel LED output, 2…48 V DC, 0.7 A
The EL2595 EtherCAT Terminal contains a constant current source for LEDs and is designed to control one or more 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. For this purpose, the EL2595 has 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, hence even extremely short flashes of light are possible. The pulse duration is adjustable from 1 µs to infinity, the flash time itself can be set through a timestamp via distributed clocks; an external trigger input is also available. Extensive real-time diagnostics, e.g. for input current/voltage and output current/voltage allow detailed monitoring 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).
EL2596 | EtherCAT Terminal, 1-channel LED output, 0…24 V DC, 3 A
The EL2596 LED strobe control terminal contains a flexible power supply unit that supplies the LED with the required current and voltage. Applications from continuous light to short light pulses in the kHz range are thus possible. Each individual flash can be triggered in a controlled manner by the control system via the distributed clocks/timestamp function. The EL2596 has a trigger output for triggering cameras and high-quality, fast current and voltage control, so that line scan cameras, for example, also benefit from constant illumination. Extensive real-time diagnostics, e.g. for input current/voltage and output current/voltage allow detailed monitoring of the LED light intensity. Thus, overdrive applications with short high-current pulses through the LED are possible. If a specifiable load corridor is exited, e.g., due to load errors, the EL2596 switches off to protect the LED (resettable).
