SMART 3G
Safety for all applications
SMART 3G series detectors are used in
various application areas, including the paper industry,
food and beverage, and cosmetic industry.
The gas detectors of the SMART 3G series are used to detect the presence of flammable substances, toxic gases, refrigerants, as well as to detect deficiencies or excess of oxygen in both classified and non-classified areas.
Basic Board
| Power Supply | 12-24 Vdc 12-24 Vdc |
| Analog Output | Uscita 4-20mA |
| Digital Output (optional) | RS485 serial output through the ST.S/IDI card |
| Relay Outputs (optional) | 3 relay outputs through the STS3REL card |
The basic board is tropicalized.
Tropicalization is a protective barrier against environmental factors such as dust, humidity, or other contaminants that could adversely affect the operation of the assembled circuit.
Certified hardware at SIL2 and software at SIL3; by creating a redundant system, even the hardware achieves a safety level of SIL3.
