Product Description:

The Beckhoff EL2521-0025, an EtherCAT Terminal output, is a terminal that generates pulse trains and frequency output signals. Since this is an advanced terminal equips with RS422, it is suitable for high-precision pulse and frequency control applications, such as motor control or stepper drive systems, or encoder emulation.

Further, the EL2521-0025, via EtherCAT communication, easily finds use in automation networks and enables fast, real-time signal processing. It has one output channel and current output is 0.05 A, hence suitable to a plethora of external devices. The two-wire connections and spring-loaded plug-in technology which are used by the terminal, help ease the installation process while also assuring tight connections are maintained. Intended for reliable use in harsh conditions, this terminal complies with vibration and shock resistance standards EN 60068-2-6 and EN 60068-2-27. It is suitable for use in gas ATEX Zone 2 environments, although it is not intrinsically safe and appropriate safety measures have to be taken when installed in potentially hazardous areas.

The EL2521-0025 comes with dimensions of 12 mm x 100 mm x 68 mm (W x H x D) which makes it suitable for applications which are space limited. For operational purposes it is rated for a temperature range of 0°C to +55°C and for storage conditions the operating temperature is -25°C to +85°C. Furthermore, it is UL, CE, and ATEX certified which guarantees international compliance. With this EtherCAT terminal comes an ESI-EEPROM that retains identity information and configuration data, streamlining system integration and servicing. The EL2521-0025 offers an ideal solution for high pulse and frequency output applications in today’s automation systems, due to its strong construction and high output capabilities.
