8411190000 Datasheet, PDF (45/58 Pages) Weidmuller – Mini Coupler / Mini Conditioner

Current Monitoring
• For AC/DC
• With and without adjustable switching threshold
• Opto-coupler output
SMSI DC O
With adjustable switching threshold
Up to 50 mA
Up to 250 mA
This series is particularly suitable for
monitoring small currents from
50 mA to 5 A.
The adjustable switching threshold
activates optionally one relay-or opto-cou-
pler output each.
