Product Description
Key Features
- Digital output identity: SIMATIC S7-400 SM 422 digital output module with isolated 16 DO.
- Load voltage: Rated load voltage: 230 V; 120/230 V AC. Permissible range: 79 V to 264 V, with a permissible frequency range of 47 Hz to 63 Hz.
- Output current: Signal "1" output current: 2 A rated value, with a permissible range of 10 mA to 2 A and permissible surge current of 50 A per cycle.
- Output protection: Short-circuit protection: Yes; clocked electronically. Following a short-circuit, reclosing under a full load cannot be ensured.
- Channel separation: Digital outputs have potential separation between channels and between channels and the backplane bus; separation is in groups of 4.
- Lifecycle status: Announcement of product phase-out.
Applications
- Redundant load control: Two outputs can be switched in parallel for redundant control of a load, only with outputs having the same load voltage.
- Digital input control: The digital outputs can control a digital input.
