Key Features
- Product designation: SIMATIC S7-400, digital output SM 422 with isolated 32 DO.
- Load voltage: Rated load voltage: 24 V DC; permissible range: 20.4 V to 28.8 V DC.
- Output current: Rated output current for signal "1": 0.5 A; permissible range: 5 mA to 600 A is omitted because it conflicts with the supplied rated value.
- Output delay and switching: The supplied product description gives a 0.15 ms output delay. Maximum switching frequency is 100 Hz with resistive load and 2 Hz with inductive load.
- Diagnostics and protection: Diagnostics, parameterizable diagnostic function and alarms, wire-break and short-circuit diagnoses, and electronic clocked short-circuit protection.
- Installation and isolation: Dimensions: 25 mm width, 290 mm height, 210 mm depth. Digital outputs have potential separation between channels in groups of 8 and from the backplane bus; isolation tested with 500 V DC.
