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.

Product Applications

Water and wastewater
Sump and sludge pits, clarifiers, digesters
Chemical storage tanks
Oil tanks
Reservoirs

Selectable pump alternation when used with two pumps to minimize pump wear
Integral 24 VDC power supply for transmitter
User selectable security lock-out of programming and/or set points
Optional process input retransmission as a current (4 to 20 mA) or voltage (2 to 10 VDC) analog signal
Analog output on pump "on" condition for activation of separate pump run time meters
