---|---|
Distributed Clocks | Yes, with Oversampling n = 1…100, accuracy << 1 μs |
Special features | Extended range 107 %, freely configurable numeric filters, TrueRMS, integrator/differentiator, non-linear scaling, PeakHold |
Functional diagnosis 1) | Yes |
Electrical isolation channel/channel 2) | - |
Electrical isolation channel/EtherCAT 2) | Functional insulation, 707 V DC (type test) |
Electrical isolation channel/SGND 2) | Functional insulation, 707 V DC (type test) |

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 that are applied to the cable shield can lead to measurement deviations up to ±FSV. |
