SMART3-R is developed to detect gases in non-classified areas, such as machinery rooms and laboratories.

Due to the optimal performance in these applications, an electrochemical cell detects toxic gases. Four smart LEDs illuminate the transparent ring to describe the detector status, and an internal buzzer is activated in alarm and fault conditions.

The SMART3-R gas detector has a standard 12-24 Vdc power supply, but a 220 Vac version can be supplied. The gas detector has three relay outputs, an RS485 serial communication and an analogue 4-20 mA output (not in the 220 Vac version).

The polycarbonate case has a global size of 130 x 130 x 74 mm. The box has two entries with M20 cable glands. Pre-formed guides can be drilled on the sides to add up to 6 M16 cable glands.

The gas detector can have a remote head connected with a RJ12 6P6C cable.
