6M
Field-mounted Two-wire Signal Conditioners 6-UNIT
POTENTIOMETER TRANSMITTER
Functions & Features
• Providing a 4 – 20 mA DC signal proportional to a potentiometer or slidewire position input
• Constant voltage excitation allows use with pots with total resistances from 100 Ω – 20 kΩ without affecting accuracy
• Minimal interaction between zero and span adjustments
• Rugged enclosure
MODEL: 6M
ORDERING INFORMATION
• Code number: 6M
• Mounting adapter (e.g. surface mounting adapter plate, model: A-01)
Note: When a mounting adapter is required, specify mounting adapter. Not included without specifying.
