Introduction
The Commander Series has three unique application configurations. The choice of application is
field selectable. The three configurations are:
• Multi-Tank Display (Application #1) – Commander will accept up to Four 4-20 mA input
transmitters and will provide a 3A SPST relay output for each input.
• Differential Level Controller (Application #2) – Commander will monitor the levels
above and below a rake and control a relay based upon the defined differential between
the two levels. In addition, a differential alarm can be programmed as well as individual
alarms for each input.
