EL9xxx | System

Each bus station must be terminated on the right-hand side with an end cap. In addition to the E-Bus, the EL9012 also covers the power contacts and is color-matched to the EL terminal series.

The EL9181 potential distribution terminal provides two potentials with 8 terminal points each for potential distribution and enables the tapping of the voltages without further terminal blocks or wiring work. The power contacts are fed through to the next terminal without connecting to the terminal points.

The EL9186 potential distribution terminal provides 8 terminal points with the 24В V potential at the front on the terminal contacts. The 24В V power contact is connected to the front-side terminal contacts and is passed through to the adjacent terminal. The 0В V power contact is not connected to the front-side terminal contacts and is passed through to the adjacent terminal. With the EL9186, the use of additional terminal blocks on the terminal strip can be reduced.

The EL9221-6000 electronic overcurrent protection terminal is a 24В VВ DC EtherCAT Terminal with an electronic protection function. The EL9221-6000 is a single-channel device and switches 24В VВ DC overcurrents off reliably. The rated current can be adjusted in 1В A steps up to a maximum of 4В A both via TwinCAT and via a mechanical button on the overcurrent protection terminal. The protected output can be fed out via a terminal contact or directly forwarded via the power contact of neighboring terminals without wiring. The operating status is displayed via an LED and in the process image.

The EL9222-6600 electronic overcurrent protection terminal is a 24В VВ DC EtherCAT Terminal with an electronic protection function. The EL9222-6600 is a 2-channel device and switches 24В VВ DC overcurrents off reliably. The rated current can be adjusted in 1В A steps up to a maximum of 4В A both via TwinCAT and via a mechanical button on the overcurrent protection terminal. The protected outputВ 1 can be fed out via a terminal contact or directly forwarded via the power contact of neighboring terminals without wiring. The operating status is displayed via an LED and in the process image.

The EL9227-4433 electronic overcurrent protection terminal is a 24В VВ DC EtherCAT Terminal with an electronic protection function. The EL9227-4433 is a 2-channel device and switches 24В VВ DC overcurrents off reliably. The rated current is fixed to 3В A/3В A. The protected outputВ 1 can be fed out via a terminal contact or directly forwarded via the power contact of neighboring terminals without wiring. The second output can be tapped via the front terminal contacts.

The EL9227-6644 electronic overcurrent protection terminal is a 24В VВ DC EtherCAT Terminal with an electronic protection function. The EL9227-6644 is a 2-channel device and switches 24В VВ DC overcurrents off reliably. The rated current is fixed to 4В A/4В A. The protected outputВ 1 can be fed out via a terminal contact or directly forwarded via the power contact of neighboring terminals without wiring. The second output can be tapped via the front terminal contacts.

The EL9501 power supply terminal generates an adjustable output voltage from the 24 V DC input voltage. This makes it suitable for supplying sensors or devices that require less than the 24 V that are usually available. It can also be used like an analog output terminal to simulate slowly varying signals but has far more output power than a 20 mA channel. The operating status is output via LED and process data. The diagnostics include the output current and the output voltage, so it is possible to integrate the terminal into an external control loop – for example, to reduce load effects.

The EL9520 potential feed terminal decouples the input and output signal with an integrated filter and enables the supply of AS interface networks from standard power supply units or from another AS interface network. The EL9520 can be placed directly adjacent to the EL6201 AS interface master terminal. The parallel operation of this combination in an EtherCAT terminal block is possible several times and saves several AS interface power supply units.

The EL9562 power supply terminal generates two electrically isolated output voltages from the 24В VВ DC input voltage. The output voltages can be tapped at the terminal with a current of 0.2В A, they are electrically isolated from each other and from the input voltage. The power contacts are looped through. The power LEDs indicate the operating status of the terminal. Connecting both voltages makes it possible to create a symmetrical DC voltage.

Терминал EtherCAT EL9576 содержит высокопроизводительные конденсаторы для стабилизации напряжения питания. EL9576 может использоваться совместно с клеммами шагового двигателя EL70x1, клеммами двигателя постоянного тока EL73x2 и клеммами серводвигателя EL72x1. Низкое внутреннее сопротивление и высокая импульсная токовая способность обеспечивают хорошую буферизацию параллельно с блоком питания. Обратные токи сохраняются, особенно в контексте приложений привода, тем самым предотвращая перенапряжения. Если рекуперативная энергия превышает емкость конденсаторов, энергия может рассеиваться через внешний тормозной резистор. Соответствующий порог может быть напрямую параметризован в TwinCAT System Manager.
