ELM3348-0000 | EtherCAT Terminal, 8-channel analog input, temperature, thermocouple, 24 bit, high-precision, 1 ksps

The 4- and 8-channel EtherCAT Terminals from the ELM334x economy series are designed for temperature measurement with thermocouples. All common thermocouple types are covered and, with a sampling rate of 1 ksps per channel, fast processes are also easy to record. The resolution is adjustable to 0.001°C. The channel properties can be adjusted individually for each channel via CoE. An exceptionally high measuring accuracy is achieved through the precise measurement of the internal cold junction.

In the ELM334x-0000 version, the 6-pin connector (push-in) is removable for maintenance purposes without loosening the individual cores. The internal ground for the external connection is also available on it in order to avoid potential differences between channels. In addition, the ELM334x can also continuously measure potential differences in order to detect impairments.

The ELM334x-0003 version with white “universal” thermocouple socket is designed in this series for the highest accuracy requirements. As a result, the thermocouple of one type can be fed into the terminal and thus measured even better. Changing the sensor in laboratory operation is even simpler with the mini socket.

Like all ELM3xxx terminals, the ELM334x devices support the TE1310 TwinCAT Filter Designer for application-oriented filter design and the typical internal functions of the ELM3xxx for data processing such as true RMS calculation, drag indicator, etc.

The fed-through power contacts simplify the potential distribution directly on the DIN rail. To reduce ambient air effects, the ZS9100-0003 shielding hood, which is available as an accessory, can be mounted on the terminal.

Extensive documentation is available from Beckhoff sales, support or measurement@beckhoff.com.

This ELM3xxx series measurement terminal enables efficient implementation of complex system-integrated data acquisition systems (DAQ) that place high demands on measurement accuracy and time synchronization.
