Zusammenfassung:A multiple safety zone valve driver system (110) for driving a plurality of valves of a valve manifold, comprising a plurality of valve drivers (20-26), wherein each valve driver is configured to drive one or more valves of the manifold, a first safe output (162) that is operative to provide and shut off power to a first one or more of the valve drivers (20-26), and a second safe output (164) that is operative to provide and shut off power to a second one or more of the valve drivers (20-26) separately from the first output (162) providing and shutting off power to the first one or more of the valve drivers (20-26), wherein the first and second safe outputs (162, 164) are configured such that in response to a first type of safety event the first output (162) shuts off power to the first one or more valve drivers (20-26) and the second output (164) maintains power to the second one or more valve drivers (20-26).
