15MS
Dual Channel Input/Output Isolators 15-RACK
POTENTIOMETER CONVERTER
Functions & Features
• Providing a DC output proportional to a potentiometer or slidewire position input
• Constant voltage excitation allows use with pots with total resistances from 100 Ω – 10 kΩ without affecting accuracy
• 50 % zero/span adjustments with minimal interaction
• 2 channels available; accomplishing economical and space-saving multi-input processing
Typical Applications
• Tank levels
• Positions
