Notes

Safety informationInput and output must be safely isolated from any hazardous live parts!

NoteThe 3 (Us+), 7 (Us+), 4 (GND 3) and 8 (GND 3) connections are internally commoned.

.

T echnical data

Current carrying capacity between 3/4 and 7/8 connections: 1 A (max.)

Use shielded signal lines!

Only use shielded signal lines for analog input and output signals.
Only then can you ensure that the accuracy and interference immunity specified for the
device can be achieved, even in the presence of interference acting on the signal cable.
