Max. 500 mA per handwheel, i.e. a total of max. 1 A
High level: rated value 24 V, limits 15 ..30 V / 2 mA...15 mA
Low level: rated vale 0 V or open, limits –3...5 V
The binary outputs are short-circuit proof.
Max. switching current per output: 500 mA (coincidence factor 100%).
For an inductive load, an external protective circuit is required for unloading
