FAQ Question?Is this module compatible with S7-400H (high-availability) and S7-400F (failsafe) systems?Answer: Yes, the SM 422 standard digital output module can be used in S7-400H and S7-400F systems for non-safety-relevant tasks. For safety-critical outputs, a dedicated F-module is required. Question?What type of front connector is required for this module?Answer: This module requires a 40-pin front connector. The specific part number depends on the connection type, for example, 6ES7492-1AL00-0AA0 for screw terminals. Question?Can this module directly drive inductive loads like contactors or solenoid valves?Answer: Yes, but it is crucial to use appropriate protective circuits, such as freewheeling diodes, across the inductive load to protect the module’s output transistors from voltage spikes when the load is switched off. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
