APPLICATIONS
The MD plus system is ideal in many process applications
requiring a closed-loop DC variable speed drive with an optional
isolated 4-20mA input and output.
Typical applications include:
• Waste water treatment
• Chemical metering processes
• Laboratory mixing equipment
• Industrial auger/mixing equipment
• Polymer injection processes
OPT420 OPTION
The OPT420 Option may be factory or field installed to any
drive in the MD Plus Series. The 4-20mA output is Loop Powered,
relying on another device in the loop for its power. Both the
4-20mA input and output are individually isolated. A second relay
output is available when this option is used to indicate alarm and
status information.
