THIẾT BỊ DÒ KHÍ DA-50 Series,GASDNA Vietnam - GASDNA Vietnam

DA-50 detects various combustible & toxic gases leaked from industrial areas for gas producers,
gas users, gas reservoirs, gas by-producers, and so on, in order to prevent any accidents in advance.

DA-50 converts digital signal into the 4-20㎃ standard current signal for output signal which
can be transmitted to various external devices such as PLC, DDC, RECODER, and so on.
Using these functions, you can easily construct the gas monitoring system more extensive
as well as more comprehensive.

DA-50 provides RS-485 communication signal and gas leakage alarm signal by relay contact output.
Besides, DA-50 has DC 4-20mA standard output which realizes max 2,500m long distance output signal transmission from sensor to receiver and RS-485 communication signal which realizes max 1000m long distance signal transmission.
