Product Description
The hydrogen alarm (NDR-H2-1B) is a device that detects leaked hydrogen gas with high accuracy and issues an alarm to alert the surrounding area of the danger. The detection threshold is a concentration of 500 ppm, and when gas is detected, an alarm is instantly sounded with a buzzer (approximately 93 dB) and an LED lamp.
The power supply is AC100V. The external output isB-contact relay (AC250V 1A, resistive load)The circuit is normally open, but when an alarm occurs the contacts close, ensuring reliable signal transmission to external devices.
In this model, the circuit is normally open and closes when an alarm occurs.Easily linked to external buzzers, patrol lights, equipment stop devices, etc.This makes it easy to build a system that can reliably and immediately issue an alarm in the event of an abnormality, or safely shut down equipment.
*When connecting an external device, please be careful not to exceed the relay contact rating (AC250V 1A, resistive load).When connecting high current devices, we recommend using a relay.
*Gas alarms are devices that require regular inspection and calibration to maintain accurate detection performance.
Please consult us in advance, especially if you are considering installing the unit in a high or difficult-to-access location.
We can also propose installation methods that take maintenance plans into consideration.
*A contact specification model (NDR-H2-1A) is also available separately.
