Input Signals | Connect to (4-20)mA standard current signals or passive switching value signals locally or via a channel card |
Output Signals |
1.RS485 bus communication signal (standard MODBUS protocol); 2.Signals of 3 sets of relays (relays1, 2, 3); contact capacity: AC250V/10A or DC30V/10A |
Alarming Mode | Audible alarm and LED visual alarm |
Display Mode | OLCD Chinese display |
Mounting Mode | Standard 19"Cabinet panel mounting |
Boundary Dimension of the Standard Rack | 19"standard 3U rack (Length x Width x Thickness:483mm x 252mm x 132.5mm) |
The 19” standard 3U panel-mounted all-metal rack has a slideway plug-in design in each channel; the standard 3U cabinet installation is characterized by easy installation, small volume (73% of AEC2392a) and anti-EMI/RFI interference;
The master control card and channel cards are set separately but have a function of synchronous display. With a large LCD Chinese display screen, the master control card can realize Chinese menu operation as well as faster and easier display and operation;
Channel cards can work independently under an independent menu. Thus, failure of the master control card or failure of other channel cards will not have an impact on normal channel cards’ gas monitoring;
Channel cards can receive 4-20mA signal or switching value signal input and be connected with various devices, including combustible gas detectors, toxic and hazardous gas detectors, oxygen detectors, flame detectors, smoke/heat detectors and manual alarming buttones, etc.;
Channel cards’ multiple output types are applicable to linkage of on-site external control devices, good for integration of the host control system (e.g. DCS, PLC, etc.);
The master control card integrates the functions of the power supply card and the one-circuit channel card. All channels can be equipped with a HART communication module, showing a strong function;
Strong output driving capacity; each circuit’s output capacity is up to 8W, to drive the integrated detector of audible and visual alarms and display;
The master control card integrates the functions of the power supply card of the former 292a and the one-circuit channel card. All channels can be equipped with a HART communication module, showing a strong function;
Channel cards have a three-color backlight LCD, which can indicate normal, failure and alarming status clearly;
With an OLED screen and an aluminum alloy wortle panel, this product looks beautiful and magnificent generally.
The control panel contains the display interfaces and operating interfaces of the master control card and channel cards, including the display screen, the LED status indicator, the alarm buzzer (installed inside the master control card) and operating keys. The master control card has ten operating keys while a channel card has three ones (see the following diagram)
