Jieyi GCE alarm box DGM-SK model complete

The alarm controller DGM-SK, as a fault alarm control unit, can connect up to 10 alarm channels to monitor whether the circuit deviates from normal. The integrated sound and light device can be used to test whether the various functions of the controller can operate normally. When one or more alarm signals are triggered (such as gas failure), the control signal sent will activate an audible alarm (buzzing sound) and a visual light alarm (red LED light) to complete the alarm purpose. Stop the sound alarm by pressing the sound alarm button, but the status of the indicator light remains unchanged; The indicator light will only automatically return to its normal state after all faults have been resolved. The alarm controller processes various collected information and transmits it to the central control room, individual control units, or external alarm devices. The controller achieves signal transmission through mechanical or inductive contact methods that comply with DIN19234 NAMUR standards.
application
An alarm controller is an alarm signal device that effectively monitors gas status or is used to monitor gas flow in gas applications. By monitoring the pressure difference between the upstream and downstream of the gas (using an electric contact pressure gauge), the weight of the gas in the bottle, and the bursting disc, it is possible to achieve single monitoring of the gas source channel or simultaneous control of more than ten channels. Flow switches, float flow meters, and large flow controllers can also be used to transmit signals and achieve effective control of flow. Design a new relay central control system to generate alarms through fax or SMS. Through programming, each channel can be independently set, that is, each channel can be selected to sound an alarm through SMS or SMS in this article, and the channel number can be defined.
Optional accessories
Electromagnetic valve controller DGM-MV, relay DGM-IT, electric contact pressure gauge and gas management system operation control terminal DGM-AX, large flow controller, steel cylinder scale gauge, bursting disc, float flowmeter, flow switch and cable monitoring.
Install
The box should be installed on the wall outside the explosion-proof area. The back of the box has 4 mounting bolt holes for installing the box on the wall. Open the casing cover by loosening the nut.
