Product Description
Key Features
- Exact module identity: SIMATIC S7-400 digital output SM 422 with isolated 16 DO.
- Load voltage: Rated load voltage L+ is 24 V DC, with a permissible range from 20.4 V to 28.8 V.
- Output capacity: Rated output current for signal "1" is 2 A; the permissible range is 5 mA to 2.4 A.
- Output protection and switching: Short-circuit protection is electronically clocked. Switching frequency is up to 100 Hz with resistive load and up to 0.1 Hz with inductive load.
- Installation and isolation: Dimensions are 25 mm width, 290 mm height and 210 mm depth; digital outputs have potential separation between channels in groups of 8 and from the backplane bus.
- Lifecycle status: Product phase-out has been announced.
Applications
- Digital input control: The outputs can control a digital input.
- Redundant load control: Redundant control of a load is possible using outputs of the same group.
