Product information
Overview
Key Features
- Digital input capacity: 16 digital inputs, with 16 simultaneously controllable inputs and 2 byte input address space per module.
- Input voltage: Rated input: 230 V; 120/230 V AC, 50/60 Hz. Signal "0": 0 V AC to 40 V AC; signal "1": 79 V AC to 264 V AC.
- Input timing: Input delay: 20 ms. For standard inputs, transition times are max. 25 ms from "0" to "1" and max. 25 ms from "1" to "0".
- Channel grouping and isolation: 16 channels are arranged in groups of 4. There is no potential separation between channels; separation from the backplane bus is provided.
- Connection and cable length: The front connector has screw terminals or push-in terminals and is ordered separately. Maximum cable length is 1 000 m shielded or 600 m unshielded.
