EYESKY ES90C-4 gas alarm control host, four channels, metal case

Description

The Visionless ES90C-4 gas alarm control host is a four-channel combustible gas alarm controller. It is composed of a general metal shell, a switching power supply, a motherboard, an interface board, an alarm and other parts.

The display part is composed of 0.8-inch digital tubes, which take turns to display the concentration of each channel, and the display is clear and can adapt to different light environments, and at the same time has channel status information indication; The key part is composed of a number of high-quality buttons, which feel good when pressed, effectively improving the user's operating feel. When the program is designed, a high-security key trigger scheme is adopted--- pressing the button to start recognition, and releasing it to complete the recognition. The key signal below 20ms is invalid, the key signal between 20ms~3 seconds is a normal key, and the key signal for more than 3 seconds is a long press; It has sound and light alarm (light alarm optional), multiple sets of alarm relay outputs (relay output can be defined by users to adapt to different occasions).

Features

◆ Controller power supply AC220±20%, 50HZ; The output Voltage is DC24V, and the power consumption of the controller < 2W.

◆ Using digital tube and LED display, long service life, high brightness, low power consumption, clear display, adapt to different light environments, can intuitively display concentration, unit, alarm, fault and other information.  

◆ The 32-bit high-performance and low-power microcontroller embedded with ST can quickly process the signal transmitted by the Detector and display the concentration information in real time.

◆ Sound and light alarm function, light alarm optional, Detector failure, low report, high alarm to send out different frequencies of sound alarm.

◆ Up to four groups of relay outputs (passive), relay outputs can be customized to adapt to different occasions.

◆ Detector signal communication mode optional: 4-20mA, RS485 (factory default 4-20mA, RS485 optional).

◆ With silencing function, you can press the silencing button to silence when the controller alarms due to misoperation or test needs.

◆ The 8-channel controller has the function of channel locking, and the channel can also be switched after locking, which is convenient for real-time detection and testing of a certain channel.

◆ High-quality buttons, large pressing area, good pressing feel, effectively improve the operation experience.

◆ The connection between the controller case door and the chassis body adopts a simple waterproof function, and the surface of the metal shell of the chassis is smooth, with a certain touch feel and compression resistance.

◆ Waterproof and dustproof terminals are used at the inlet of the controller, which can effectively fix the incoming wire.

◆ Wall-mounted installation, convenient for controller disassembly, optional mounting bracket.
