GMS-2500-LB

Introduction
GMS-2500-LB is multi-channel gas alarming unit to monitor gas leakages from more than one gas detectors simultaneously. GMS-2500 is composed of one alarming unit & more than one receiving units. While each receiving units in GMS-2500 receive density signals from external gas detectors, when the density becomes higher than alarm value, receiving units automatically give signal to alarming unit to sound alarm.
GMS-2500-LB transmits the relay output and standard current output signal 4-20㎃ to various controllers such as PLC, DDC, recorders, and computers for composition of integrated gas monitoring system.
Features
- Centralized gas monitoring is available by connection with more than one gas detectors.
- Receiving 4-20㎃ analogue continuous signals from more than one gas detectors simultaneously and displaying the digital signals accurately by built-in high resolution A/D converter.
- User programming alarm range, alarm delay time, and so on, by built-in micro processor.)
- Bar graph displays the alarming density for maximum visual effect.
- Built-in high resolution D/A converter for accurate transmission of 4-20㎃ standard current output signal to external controllers (PLC/DDC).
- High/low relay output for interlocking with external devices such as fan.
- Robust aluminum alloy casing & frame.
