Product information
Overview
Applications
- Controlling digital inputs: The digital outputs can control a digital input.
- Redundant load control: Two outputs can be switched in parallel for redundant control of a load, only with outputs having the same load voltage.
Key Features
- 16 isolated digital outputs: The SM 422 module has 16 digital outputs with potential separation between channels and the backplane bus. Channel separation is arranged in groups of 4.
- 120/230 V AC load voltage: Rated load voltage is 230 V; the stated load voltage is 120/230 V AC, with a permissible range from 79 V to 264 V and a frequency range from 47 Hz to 63 Hz.
- 2 A rated output current: Signal "1" output current has a rated value of 2 A and a permissible range from 10 mA to 2 A. Permissible surge current is 50 A per cycle.
- Short-circuit protection: Short-circuit protection is provided electronically. Following a short-circuit, reclosing under a full load cannot be ensured; the load voltage or output signal must be interrupted as stated.
- Output switching performance: Response time is max. 100 ms. With a resistive load, output delay is max. 1 ms from "0" to "1" and max. 1 AC cycle from "1" to "0".
- Phase-out announcement: The product lifecycle is Announcement of product phase-out.
