DA-50-EO

Introduction
(영문메뉴얼업데이트예정)
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 2500m long distance output signal transmission from sensor to receiver and RS-485 communication signal which realizes max 1000m long distance signal transmission.
Features
Digital Process
Digital process based on built-in micro processor realizes various artificial intelligent functions which result in more convenient, more accurate, and more efficient gas detection environment.
Polycarbonate Housing
Polycarbonate housing which has corrosion proof material and water proof structure is the best application to detect corrosive gas.
Self Diagnosis
Digital processor automatically diagnoses the sensor signal and sends 2mA error signal output on the malfunction in the sensor.
