The EL2564 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 5…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:

• flexible input voltage 5…48 V DC

• adjustable color component per channel with multicolor LEDs (adjustment of the duty cycle)

• adjustable total brightness across all channels

• adjustable frequency 1…16.000 Hz, for the avoidance of stroboscopic effects and the realization of visible flashes at low

frequencies

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.

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.

Special features:

• Pulse train (frequency output), RS422

• Different operating modes

• Frequency modulation

• Pulse direction setting

• Incremental encoder simulation (1x ABC, 2x AB)

• Integrated path control

• Synchronized operation through distributed clocks XFC technology possible
