E2670-O2 Rev 10.05.2023 Product description E2670 is a series of flameproof gas detectors-transmitters intended for operation in safe zones and ATEX Zones 2 and 22. E2670 series devices are based on the PluraSens® multifunctional platform and provide all its features. The instruments utilize gas sensors of various types with excellent repeatability, stability, and long lifetime.
E2670-O2 Rev 10.05.2023 Operating conditions The device should be used in a basic electromagnetic environment, where the latter is defined in EN 61326-1. Avoid strong mechanical shock and vibrations. Although E2670 series devices are suitable for use in the presence of flammable dust, special precautions should be taken when operating in a dusty environment.

E2670-O2 Rev 10.05.2023 NOTE! The outputs are not galvanically isolated from the external power supply and share a common 0V. Allowed load resistance limits are stated in the Specifications table. To power the instrument from an external power source, connect terminals 0V and +U to the source.
E2670-O2 Rev 10.05.2023 Operation Turn on the power. The instrument warm-up time takes about 1 minute after switching on and the final sensor stabilization time to maximum accuracy takes about 30 minutes, but depending on the sensor type, it can take up to several hours. The operating status is indicated by the LED on the PCB of the device.
