Beckhoff ELM3348-0030 | EtherCAT Terminal, 8-channel analog input, temperature

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 arealso easy to record.

The resolution is adjustable to 0.001°C. The channel properties can be

adjusted individually for each channelvia 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 differencesbetween channels. In addition, the 

ELM334x can also continuously measure potential differences in orde

to detect impairments.

Like all ELM3xxx terminals, the ELM334x devices support the TE1310

TwinCAT 3 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.

The individual calibration certificate for each device, in accordance with

ISO 17025 or DAkkS, depending on the device variant, can be downloaded

here. These calibration certificates are issued for Beckhoff by an accredited

service provider. Recalibration on request.

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.
