Product Description:
Beckhoff EtherCAT terminal EL3121 is a high-performance differential input signal module used in the industrial applications for analog signal processing. Being a member of the EL EtherCAT Terminal Series, the EL3121 is famous for the high accuracy and reliable work. This terminal has a resolution to 16 bits, and therefore delivers reliable signals meeting the necessary levels, it is ideal for operations that require extreme accuracy. The fact that it uses the digital differential input type improves the signal accuracy through reducing on potential electrical noise as well as on signal loss that is inherent through the use of cables over long distances. Having a working range of -25 to +60°C the EL3121 is suitable for any standard and some harsh environments. The terminal has the surge voltage resistance up to 35V to prevent electrical surge and to maintain performance in electrically noisy environment. Besides, an input filter limit frequency is set to be 5 KHz, which gives this module a good response speed and effective noise rejection when dealing with Dynamic signals without compromising the signal quality.
The EL3121 uses a current of approximately 130 mA through the E-bus which is a power supply of EtherCAT networks. It measures approximately 55 grams and is therefore ideal for use in industrial control systems because it does not add bulk to the overall system.
This terminal is most suitable for use in applications that may demand precise signal measurements or control as well as monitoring. Due to the high functional capabilities and increased degree of protection the EL3121 EtherCAT terminal is created for today’s industrial conditions and ensures the stable work in the difficult environment.
