Product Description:

The EJ3214 is a Beckhoff manufactured EtherCAT Plugins Module. It belongs to the EJ Plugins series. It is considered an effective device which is well suited for industrial automation applications.

The EJ3214 EtherCat Plugins is built to function reliably across -25…+60°C industrial temperature ranges. It is designed to tolerate very high ambient humidity up to 95% as long as condensation does not occur which ensures internal electronics remain safe. For Pt sensors, it can read between -200 to +850 degrees Celsius of temperature. On the other hand, if Ni sensors are connected it can detect temperature ranging between -60 to +250 degrees Celsius. The module can simultaneously connect and read up to four different temperature sensors. This plugin module meets industrial electromagnetic compatibility standards which means it cannot be affected easily by electrical noise. It is highly flexible and supports a broad variety of RTDs such as Pt100 – 1000 and Ni100 - 1000. It is able to handle signals with frequency components up to about 1 kHz which helps reject very fast noise while maintaining sensor signal integrity. It can be safely stored in -40…+85°C temperatures without damage.

The EJ3214 EtherCat Plugins draws relatively low power up to 160 A from the EtherCAT bus which ensures minimal load on the network's power budget. It conforms to EN 60068-2-6 and EN 60068-2-27 which makes it able to withstand industrial vibrations and occasional shocks without malfunctioning. The module comes with smart onboard features like smoothing noisy data, triggering alarms on out of limit temperatures and flexible wiring options. It supports both common RTD wiring methods, with 3 wires offering compensation for wire resistance for more accurate measurements.

Frequently Asked Questions about EJ3214:

Q: What type of electrical isolation does the EJ3214 provide and why is it important?

A: The EJ3214 offers 500 V isolation between E-bus and field potential. This prevents interference and protects the communication network from field wiring faults.

Q: How does the integrated digital filter benefit the EJ3214 EtherCAT Plugin in industrial applications?

A: The digital filter helps to smooth out noise from unstable signals. This ensures highly accurate and stable temperature readings during operations.

Q: Why does the EJ3214 support 2- and 3-wire connections for RTD sensors?

A: 2- and 3-wire options provide installation flexibility. The 3-wire method compensates for lead resistance, improving overall measurement precision.

Q: What is the significance of the 1 kHz input filter limit frequency in the EJ3214?

A: A 1 kHz filter limit frequency ensures fast noise rejection. This preserves the true sensor signal quality for accurate readings.

Q: How does vibration resistance improve the performance of the EJ3214 in rough environments?

A: Vibration resistance allows the EJ3214 to maintain consistent readings even in heavy machine environments. It ensures module longevity under mechanical stress.
