Overview
BOSEAN BH-50 single-channel multi-function host alarm control cabinet is a single-channel (4-20) mA/RS485 transmitter signal input intelligent controllable system with high stability, high accuracy and high intelligence. The system has rich external control ports, and users can freely choose the type and access port of the attached transmitter. On-site detection and alarm can be carried out through simple setting. The system has integrated sound and light alarm, and provides relay normally open control terminal. It is widely used in occasions where toxic and harmful gases need to be detected. When the on-site gas index exceeds or falls below the set standard, the system will trigger a series of actions such as alarm, exhaust, trip, etc.
Features
1. Single signal input, support (4-20) mA or RS485 transmitter signal.
2. High Stability, High Accuracy and High Intelligence.
3. The external control ports are abundant, and users can freely choose the type of connector and access port.
4. Easy to set up for on-site detection and alarm configuration.
5. Integrated sound and light alarm function.
6. Provide the normally open control terminal of the relay.
Principle
The system analyzes and displays the current gas concentration of each channel by collecting standard 4~ 20mA signal input or RS485 communication input (optional). According to the set Alarm threshold, the system operates the relevant alarm signal, and can transmit the detection information to the computer through the RS485 bus.
Applications
Where toxic and harmful gases need to be detected
Steps
1. Select and hook the appropriate transmitter to the input port.
2. Simple system settings, configuration detection parameters and Alarm threshold.
3. The system starts to collect signals and display gas concentration.
4. When the concentration exceeds the standard, the system automatically triggers the integrated sound and light alarm and relay control action.
