Product Description:
The EL7211 from Beckhoff is a high performance EtherCAT terminal designed for precise motion control applications. It offers a 4.5 A output current which ensures reliable actuation in industrial environments. The terminal is specifically engineered to drive DC motors and other inductive loads using push pull technology.
The EL7211 terminal supports a wide rotating field frequency range from 0 to 599 Hz which enables compatibility with varied motor speeds. It includes advanced safety features such as short circuit protection and overload protection for safe and consistent operation. The terminal operates with a 24 V DC switching voltage and integrates one output channel. It is equipped with diagnostic LEDs that allow quick status assessment during runtime. The terminal PWM clock frequency is maintained at 16 kHz to ensure smooth and accurate motion control. Its weight is approximately 95 grams. The EL7211 terminal has a typical E bus current consumption of 120 mA which helps in energy efficient integration. Its housing is made from durable polycarbonate which resists wear in industrial environments. The terminal is DIN rail mountable which simplifies its installation within control panels. Its permissible operating temperature range lies between 0°C and +55°C which ensures stability in normal production conditions. The terminal stripping length of wires is between 8 mm and 9 mm for a safe connection. Its storage temperature ranges from -25°C to +85°C which supports long term warehousing without damage.
The EL7211 terminal offers compact dimensions of 24 mm width by 100 mm height by 68 mm depth. It has two power contacts that handle the load voltage separately. Electrical isolation is provided up to 500 V between the E bus and field potential for added operational safety. The terminal is widely adopted for precise control where response speed and protection are critical.
