704C
Controller
by MJK
The MJK
704 controller is a microprocessor based unit used with a 4 - 20 mA
signal. This controller is designed to work with a variety of sensor
styles and control up to four pumps. Functions for control, alarm,
indication and flow calculation are selectable. The controller is
supplied with data communication capabilities so that it can be connected
to a SCADA System.
Applications
include water and wastewater pump stations and processing tanks, water
towers and reservoirs, deep wells, lakes, rivers, and storage tanks.
