multi-channel gas detection control unit

The ECHO 28 from Simtronics, is an expandable monitoring panel that covers the middle ground between the small controllers like ECHO 2/4, and the larger modular systems such as MDXI. It can be used as a wall mounted or rackable unit, providing constant supervision of gases and flammable or toxic fumes. As well as constant supervision of the risk of lack of oxygen. It utilizes Modbus interface, and data handling is processed by PLCs. Plus, it has an 8 relay expansion module.
