Traditional and connectable

Mod. DSU816

The DSU816 is a unit made up of a general module (DSU816-M) capable of managing up to 8 19” racks that are interconnectable. Each rack can contain up to 8 autonomous measurement modules
(DSU816-Z), each fitted with two inputs. This amounts to a connectivity that can go up to 128 toxic gas and/or explosive gas detectors for a single general module.
The unit was designed to provide intuitive use for the end user.
By connecting it to one or more Dalemans detectors, you will benefit from a very high performance installation and one which is especially well adapted to applications in the industrial sector.
