APPLICATION SCENARIOS |
| ◆ Eight independently isolated AC output channels support high-load switching. |
◆ Industrial heaters, valves and contactors using 120/230 V AC. |
| ◆ Green channel LEDs indicate output status during commissioning and service. |
◆ S7-400 process and manufacturing control cabinets. |
| ◆ Internal and external fault LEDs indicate fuse or load-voltage conditions. |
◆ Retrofit of installed SM 422 output stations. |
| ◆ Official current limits support coordinated thermal and load planning. |
◆ Lifecycle spare-part support where original field wiring must be retained. |
