RS485 interface (option) |
Modbus protocol with 19200bps |
|
1)Wall mounting, real time detect IAQ
2)With Japanese famous semiconductor mix gas sensor. 5~7 years lifetime.
3)The sensor is sensitive to VOC such as various kinds of odorous gases and combustion gas in the room (smoke, CO, alcohol, human odor, material odor).
4)Two types available: indicator with 6 LED indicator lights and transmitter without indicator lights.
5)Indicator type is specially designed with 6 indicator lights to indicate different IAQ levels.
6)Transmitter type is designed to provide one 0~10VDC analog output corresponding with real time detected VOC values.
7)One on/off output optional for indicator type. Four setting IAQ value ranges can be selected to control the relay output via a set of jumpers
8)RS-485 communication interface is another optional for both Indicator and transmitter types. 15KV antistatic protection, independent address setting.
