EL2xxx | Digital output

The EL1262-0010 is a universal, high-performance oversampling terminal for input and output signals. It contains two input and two output channels that can all be operated simultaneously at up to 10В Mbit/s. It can thus resolve binary states with up to 100В ns fineness. Electrically it can read and output differential RS422 (full duplex), RS485 (half duplex) as well as 5В V single-ended. Termination and bias are electronically switchable for serial operation. This makes it suitable for the most demanding high-speed applications, e.g. laser control or the emulation and read-along of serial protocols. It thus extends the application range of the previous EL1262/EL2262 with 1В Mbit/s by a factor of 10.

The EL2024 digital output terminal connects the binary 24В VВ DC control signals from the automation device on to the actuators at the process level with electrical isolation. TheВ EtherCAT Terminal contains four channels whose signal state is indicated by LEDs. Direct connection of four 2-wire actuators is possible because the terminal has four ground connection points.

The EL2042 digital output terminal connects binary 24В VВ DC control signals to the actuators with electrical isolation. Each EtherCAT Terminal contains two channels whose signal state is indicated by LEDs. The EL2042 enables connection of loads with current consumption up to 8В A if the outputs are connected in parallel. Two 3-wire actuators can be connected directly to the EL2042.

The EL2202/EL2202-0100 digital output terminal connects the binary control signals from the automation device on to the actuators at the process level with electrical isolation. This terminal benefits from very small output delay and is therefore suitable for signals requiring particularly fast output. The EtherCAT Terminal has a push-pull output that can be actively switched to 24В V, 0В V or high-impedance. The EL2202-0100 contains two channels. LEDs indicate the signal state of each channel.

The EL2535-xxxx output terminals control the output current through pulse width control of the supply voltage. They 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 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.

The EL2596-0010 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 EL2596-0010 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 EL2596-0010 switches off to protect the LED (resettable).

The EL2622-0010 output terminal has two relays each of which has a single contact. The relay terminal switches at the zero voltage crossing to protect the contacts and is particularly suitable for capacitive loads such as LED lamps. A practical test was able to show that an EL2622-0010 remained fully functional at a capacitive continuous current load of 4В A after 200,000 switching cycles (for details see documentation). The power contacts are not passed through. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.

The EL2712 output terminal uses a power switch to control mains voltage from 12В V to 230В VВ AC. The switching element is a triac, which is connected to the power contact potential. As a semiconductor switch, it is not subject to wear. The steady load capacity of a digital output is 0.5В A. The EtherCAT Terminal has two independent outputs, whose signal state is indicated by LEDs.

The EL2904 TwinSAFE component is a digital output terminal with four channels. It switches 24В VВ DC actuators with up to 0.5В A per channel and has four fail-safe outputs. The outputs are controlled by a TwinSAFE Logic-capable component via FSoE. The component automatically switches off if it detects an error (fail-stop).

With the EL/ELM264x (Reed) and ELM274x (Solid-State) Beckhoff is considerably extending the usage possibilities of the integrated measurement technology of the ELM3xxx series as well as the normal EL3xxx/EL4xxx analog inputs and outputs, because several sensors or sources can now be connected at the same time to one analog input channel.
