Introduction

DA-90-10 is an on-site indication type gas detector and a digital transmitter based micro-processor. It detects various combustible & toxic gases leaked from industrial areas and It displays its concentration and 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. If the gas concentration is over the alarm value set, its light bar and buzzer are activated automatically. DA-90-10 provides RS-485 communication signal and gas leakage alarm signal by relay contact output.

Features

Digital Process

Digital processor based on built in micro processor realizes various artificial intelligent functions which result in more convenient, more accurate, and more efficient gas detection environment.

Self-Diagnostic

Digital processor automatically diagnoses the sensor signal and sends 2mA error signal output on the malfunction in the sensor.

Gas Concentration Display

Display the measured gas concentration on FND and easily check it in dark environment.

User Programmable Menu

User programmable calibration density and detection range etc for user’s own operating functions.

Multi Signal Output

Various output signals - DC 4-20mA, 2 step-relay contact, & RS-485(option) – provides best networking with all kinds of devices & equipments.
