Description

E2658 series is a new line of flameproof detectors and transmitters intended for use in ATEX Zones 2 and 22. 

E2658 series devices are based on PluraSens® multifunctional platform.

Hydrogen Sulfide detector-transmitter E2658-H2S utilises novel fully calibrated and temperature compensated gas sensor with excellent repeatability, stability and long lifetime.

To connect the detector to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol. We recommend to set the output scale within 20-100% of the detection range.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. For 0...100 ppm range alarm set-points are 10 and 20 ppm. For 0...2000 ppm range alarm set-points are user settable within 5-95% of the detection range.
