Technical data

EPP3504-0023

Analog inputs

4 channel (differential)

Time relation between channels to each other

Simultaneous conversion of all channels in the box, synchronous conversion between devices, if DistributedClocks will be used

ADC conversion method

ΔΣ (Delta-Sigma) with internal sample rate

8 Msps

Cutoff frequency input filtering hardware
(see explanations within chapter Features/ Firmware filter concept)

Before AD converter:
Hardware low pass -3 dB @ 30 kHz
type butterworth 3th order

Within ADC after conversion:

Low pass
-3 dB @ 2.6 kHz, ramp-up time 300 µs

type sinc3/average filter

The ramp-up time/ settling time/ delay caused by the filtering will be considered within the DistributedClocks-Timestamp.

Note to cable length

Signal cable lengths to the sensor / encoder over 3 m must be shielded, the shield design must be in line with the state of the art and be effective. For larger cable lengths >30 m a suitable surge protection should be provided if appropriate interference could affect the Signal cable.

EMC notes

In case of push-in connectors, ESD air discharges conforming to EN 61000-6-4 into the connectors or to the lines connected there can lead to measurement deviations up to ±FSV within the respective channel or to other channels by crosstalk.

Peak voltages (surge) conforming to EN 61000-6-2 into the Up supply at set connection “Connect Up- to GNDA“ within CoE (F800:01) can lead to measurement deviations up to ±FSV.

*) Real applicable approvals/markings see type plate on the side (product marking).
