Product information
Overview
Key Features
- Digital output capacity: 8 isolated digital outputs with 0.5 A rated output current for signal "1".
- Load voltage: Rated load voltage is 24 V DC, with a permissible range from 20.4 V to 28.8 V.
- Protection and diagnostics: Electronic short-circuit protection is provided; diagnostics include wire break, short-circuit, missing load voltage, and parameterizable diagnostic alarms.
- Channel and bus isolation: Digital outputs are potential-separated in groups of 8, with optocoupler separation between the channels and backplane bus.
- Connection: A 20-pin front connector is required.
- Output group current: Total current is up to 4 A per group for horizontal installation up to 40 °C, or 3 A per group up to 60 °C.
