Multiplex  Controller: Model MUL-120-123P

The Multiplex Controller is a microprocessor based three (3) pump controller that alternates between three (3) pumps. Built-in time  delays prevent more than one pump from turning on or off at the same time. All  three pumps may be manually operated by the multiplex controller. The multiplex controller requires a minimum of four (4) float switch inputs. LED's indicate the float and pump status. The level sensor option is available to enhance the multiplex controller.
