Product information
Overview
Key Features
- Digital output capacity: Has 8 isolated digital outputs with electronic short-circuit protection and a green status indicator per channel.
- Load voltage: Rated load voltage L+ is 24 V DC, with a permissible range from 20.4 V to 28.8 V.
- Output current: Rated output current for signal "1" is 2 A; the permissible range is 5 mA to 2.4 A for 0 to 40 °C and 5 mA to 2.4 A for 40 to 60 °C.
- Output timing: Maximum output delay with resistive load is 100 μs from "0" to "1" and 500 μs from "1" to "0".
- Isolation and connection: Digital outputs have potential separation between channels in groups of 4 and from the backplane bus by optocoupler. The required front connector is 20-pin.
- Installation and dimensions: Total output current per group is 4 A for horizontal installation up to 40 °C or 60 °C and for vertical installation up to 40 °C. Dimensions are 40 mm × 125 mm × 120 mm.
