Dual channel gas detector controller host

Dual channel gas detector controller host

Function Overview:

It is a multifunctional device that collects gas concentration from gas transmitters, displays real-time concentration on the panel, and provides alarm indication, alarm reminder, and alarm control based on relevant parameters.
The product has a dual channel four digit 7-segment digital display tube, and relevant parameters can be viewed and configured through the "ESC", "UP", and "OK" keys.

Collection and upload interface:

Default two 4-20mA channels for data acquisition; The RS485 channel is set as the upload interface by default.

RS485 default communication properties: 9600, n，8，1。

When the RS485 port is configured for acquisition function, the device simultaneously collects data from both 420mA and RS485. When both interfaces collect data, the concentration value is taken as 420m data.

installation dimensions

Dimensions: 240 * 178 * 81 (in millimeters).

Indication function:

The device can simultaneously collect two gas channels

Each channel has alarm indication, fault indication, and normal indication.

Indication alarm function

1. Indication function

Dual channel gas detector controller hostTwo gas channels can be collected simultaneously.

Each channel has alarm indication, fault indication, and normal indication.

2. Alarm function

When the device alarms, the corresponding channel's alarm light will light up and the buzzer will sound.

1) Flashing once per second: low report;

2) Flashing twice per second: high alarm;

3) Always on: Alarm, but muted.

When the device alarms, the sound and light alarm interface will output a 24V driving signal

1) The sound and light alarm interface can be configured with functions:

2) Function: Sound and light alarm, light alarm:

3) Output: level, pulse.

The motherboard comes with a built-in buzzer function, and an external alarm indicator device with only a light alarm can be selected,

3. Mute operation

There is a "Mute" button configured on the operation panel.

When the "Mute" button is pressed, the buzzer will turn off and the alarm light will turn on normally. When there is a new one

When an alarm occurs, the mute function automatically fails. When the sound and light alarm output (VL) is configured as "light output", the mute function is invalid for this interface. When the sound and light alarm output (VL) is configured as "sound and light output", the interface does not output a signal in the mute state.

To cancel the mute, press "ESC" on the real-time concentration display interface.
