HOW THE PRODUCT WORKS
The RD3000E Gas Leakage Detection Alarm Controller centralizes signals from compatible gas detectors across industrial sites. It supports 1–16 detection channels, accepting three-wire 4–20 mA detectors and RS-485 bus-type detectors, and can upload RS-485 communication data to host software. Depending on the selected detectors, the system can monitor combustible gases, toxic and harmful gases, temperature, and humidity.
A large LCD displays live concentration readings, and users can adjust high and low alarm setpoints. The controller provides low alarm, high alarm, and fault alarm modes. When a configured reading reaches its alarm condition, the controller issues audible and visual alarms and can drive exhaust ventilation or other connected equipment through relay outputs. Detector selection and setpoints must be matched to the target gas and site requirements.
The RD3000E accepts three-wire 4–20 mA analog inputs and RS-485 bus-type detectors. Its listed outputs include switch signals, RS-485, and Ethernet. Two groups of dry normally-open relay contacts are specified, rated 10 A at 250 VAC. Confirm compatible detector models, communication protocol, channel allocation, relay loads, and host software interface before system integration.
The controller automatically stores at least 10,000 alarm records and uses two-level password management. Main supply is 85–265 VAC, 50/60 Hz; an optional backup supply uses two rechargeable 12 V / 7.2 Ah lead-acid batteries. The wall-mounted enclosure measures 500 × 360 × 122 mm and weighs about 15 kg. Verify environmental limits, mounting clearances, cable routes, and certification documents for the supplied configuration.
For a system quotation, provide the site type, target gases, detector models and quantity, 4–20 mA or RS-485 interfaces, alarm setpoints, relay-driven equipment, Ethernet or host software needs, backup power requirement, and installation environment. This helps match the multi-channel gas detection alarm controller to compatible detector signals and site alarm requirements.

APPLICATIONS
Centralize compatible gas detector signals and alarms across hydrogen station or production facility detection points.
Monitor configured combustible and toxic gas detection points and route alarms to ventilation or other equipment.
Connect multiple detectors for centralized readings and low/high alarm handling, subject to site design and detector compatibility.
Use multi-channel alarm control where industrial risk assessment calls for gas leak monitoring and control-room reporting.
