Key Features
2 digital inputs and 2 digital outputs; the inputs are current-sinking, while the outputs use MOSFET solid-state switching with current-sinking/current-sourcing.
Input and output rated voltage: 24 V DC. Input signal "0": 0 to 5 V; input signal "1": +15 to +30 V.
Permissible supply voltage: 20.4 V to 28.8 V DC.
Standard input delay is selectable in groups of four: 0.2 ms, 0.4 ms, 0.8 ms, 1.6 ms, 3.2 ms, 6.4 ms or 12.8 ms.
Maximum switching capacity is 0.5 A with a resistive load and 5 W with a lamp load.
Lifecycle status: Active Product.
