Series MPCJR Pump Controller
One or Two Pump Control with Built-In Alternation
The Mercoid MPC Junior Pump Controller provides versatile level control in a standard 1/4 DIN package. Designed for use with almost any style level transmitter the unit displays the present level and main set point value. Incorporated in the MPC Jr. is programmable level differential for on/off control of one or two pumps, valves, or other devices through two SPDT relays. Also featured are two additional programmable alarm contacts with front alarm light indication.
The MPC Jr. is flexible and incorporates a user-friendly programming menu. The front face meets NEMA 4X for outdoor panel mounting.
