Det-Tronics UD10S5N25SB2 Gas Display Unit

Feature & Principle

It is an explosion-proof universal display unit from Det-Tronics FlexVu UD10 series. It receives 4-20mA analog signal from remote gas sensors and converts the signal into readable gas concentration values on LCD. Three relay outputs support high/low alarm and fault interlock. Non-intrusive magnetic calibration allows adjustment without opening the enclosure in classified hazardous zones. Built-in continuous self-diagnosis detects sensor failure, circuit fault and power abnormality. It can work with Det-Tronics PIR9400, GT3000 and other gas detectors for fire and gas safety systems.
