combustible dust – Part 11: Protection by intrinsic safety 'iD'
Inputs
Each input can be operated from a NAMUR sensor or a mechanical contact
(if mechanical inputs are used). Do not apply any nonintrinsically safe
signals to this module.
When using an intrinsically safe electrical apparatus according to EN50020,
