Product information
Overview
Key Features
- Digital input capacity: 8 digital inputs with an AC input voltage type and an input characteristic curve in accordance with IEC 61131, type 1.
- AC input voltage: Rated input value: 120 V; 120/230 V AC (47 … 63 Hz). Signal "0": 0 to 40V; signal "1": 79 to 264V.
- Potential separation: Digital inputs have potential separation between the channels, in groups of 1, and between the channels and backplane bus; the latter uses an optocoupler.
- Front connection: Required front connector: 40-pin.
- Installation limits: Maximum quantity is 8 for horizontal installation up to 60 °C and 8 for vertical installation up to 40 °C.
- Product lifecycle: Product cancellation.
