LT range : the modular platform

NATO code of LT with LT200 CPU : 7022-14-577-6051

Mechanical and hardware presentation

- ROBUSTNESS : each module is enclosed in a aluminium cabinet which allows a protection against electro-magnetic interference and a good thermal dissipation.

- COMPACITY: Height x Depth : 105 mm x 84 mm ; Width = 25mm x Number of modules

- MODULARITY : LT supports up to 15 I/O blocks. A block has between 2 and 5 modules.

A logical block has between 8 and 32 inputs or outputs.
An analogue block has between 4 and 16 channels. 

Up to 2 extension racks.      Width of the base on demand.

The classic LT has connectors with screw terminals.

The base is fixed by asymmetrical DIN rail mounting (EN 50035-G32  (32 x 15mm)) or by brackets for screwing to a grid or a plate.
