Product information
Overview
Key Features
- 32 isolated digital outputs: Provides 32 digital outputs with potential separation between channels and the backplane bus; channel separation is arranged in groups of 8.
- 24 V DC load voltage: Rated load voltage is 24 V, with a permissible range from 20.4 V to 28.8 V.
- 0.5 A rated output current: Rated output current for signal "1" is 0.5 A; the permissible minimum is 5 mA.
- Electronic short-circuit protection: Digital outputs have clocked electronic short-circuit protection.
- Configurable diagnostics: Diagnostic function, diagnostic alarm and hardware interrupt are parameterizable; wire-break and short-circuit diagnostics are available.
- Output switching frequency: Maximum switching frequency is 100 Hz with resistive load and 2 Hz with inductive or lamp load.
