ECHO 28
The ECHO 28 controller covers the middle ground between the small controllers like ECHO 2/4 and the larger modular systems such as MDXI. The single unit design keeps the cost down.
Features
Evolutionary unit from 4 to 28 channels of measurement.
- Wall mounted or rackable unit designed for an evolutionary solution.
- Constant supervision of gases and flammable or toxic fumes.
- Constant supervision of the risk of oxygen deficiency.
Application
This unit completes our range of rackable industrial units and perfectly meets the requirements of partly industrialised sites and service sectors.
