Special features:

• suitable for simple lighting tasks and continuous LED operation

• max. output current 300…700 mA

• optional automatic operation in case of communication interruption

• support of XFC technology timestamp

• synchronized operation through distributed clocks XFC technology possible

Recommended use:

• The EL2564 is the right choice for lighting tasks with RGBW LEDs in voltage

mode.

• The EL2595 LED terminal of the 1st generation can be used for current-regulated

control of LEDs.

• The EL2596 and EL2596-0010 are the significantly more powerful successors of

the EL2595 and are therefore suitable for applications requiring high-precision

current- and voltage-controlled control of LEDs.

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).

The EL2564-0010 digital output terminal controls LEDs with integrated series

resistor via an adjustable (ground switching) PWM signal.

Common anode RGBW LEDs can be controlled with the four channels.

The operation with four LEDs of the same color is also possible with the

terminal. The terminal has a flexible input voltage of 8…48 V DC. 

The output voltage corresponds to the input voltage. For the operation of

multicolor LEDs the color portion per channel is adjustable. 

Thus any color mix can be realized. In addition to the color mixing per channel,

the adjustment of the total brightness over all channels is also possible.

Another parameter that can be adjusted is the frequency. By setting the

frequency in a range of 1…16.000 Hz, stroboscopic effects can be avoided.

Furthermore, visible flashes can be realized by the low frequencies.

Special features:

adjustable frequency 1…16.000 Hz, for the avoidance of stroboscopic effects

Optimized control of proportional valves with PWM

The EL2535-xxxx output terminals are specially designed for the precise

control of single and double-coil proportional valves and proportional

solenoid valves. They regulate the output current through pulse width

modulation (PWM) of the supply voltage and are electrically isolated

from the E-bus. The current values (0 to maximum output current) are

specified by the automation device through a 16-bit value.

The output stages are protected against overload and short circuit.

Each EtherCAT pulse width current terminal contains two channels

whose signal state is indicated by LEDs. The light emitting diodes simplify

local diagnosis by displaying typical load and wiring faults.

Special features:

• 2 PWM outputs with push-pull output stage

• suitable for inductive loads > 1 mH

• max. output current 3.5 A per channel at 24–48 V DC nominal voltage

The EL2522 incremental encoder simulation terminal (pulse train)

outputs a frequency-modulable signal on two channels with four

outputs. The signal can be used to control motor drivers or other

signal receivers, which are controlled by single cycles.

The pulse sequence and pulse number can be specified directly

via the process data in the frequency. Alternatively, the integrated

path control can be used. For each channel the operating mode

(frequency modulation, pulse/direction specification and incremental

encoder simulation) can be selected. In addition, the EtherCAT

Terminal can control three output channels in the ABC encoder

simulation.
