GDB9 Intelligent Gas Alarm Controller

Description

GDB9 series gas alarm controller is used to detect the concentration of the gas to be tested in the ambient air. When the concentration of the gas to be tested reaches or exceeds the preset alarm value, the controller immediately sends out an audible and visual alarm to remind us to take safety measures in time and start the actuator to control the exhaust or other peripheral equipment.

Functions Features

★With 32 4-20mA analog inputs or 150 RS485 inputs
★The system uses a 32-bit processor as the control unit, with high sensitivity and fast processing speed
