1.5. HARDWARE FEATURES
The relay has an aluminum case (5052 H32) 1.5 mm thick with a sand texture surface and
dimensions corresponding to 1/3 of a 19’’ rack with 5 units height.
It incorporates the required elements for a frontal fix and the boards are fixed to the rear
panel. It also includes adaptable anchoring designed to facilitate the relay`s insertion into a
control panel. All those elements have been designed to prevent the relay`s components
from suffering the effects of vibration and other environmental factors.
