TMC430 Digital Pump Controller


The Time Mark model 430 pump controller is a versatile and advanced liquid level/pump management system. The Model 430 was designed to control up to three pumps with a 4-20mA input. It can also be used to control 2 pumps with a 4-20mA input and backup floats or to simply control two pumps with only float inputs. Alarm inputs are provided, if necessary, and may be disabled through the menu system if not used. Alarm inputs are: “SF” – seal fail, “OT” – over temperature, “CF” – contact failure, and “SP” – spare (eg. a second seal fail). A relay output is provided for the level alarm (either high or low), depending on pump configuration; “pump UP” or “pump DOWN”.
