l applicable with standard Modbus RS485 signal equipment.
l 4 groups of public relay output (Fault alarm, First level alarm, Second level alarm)
l provide standard RS232 or RS485 interface to communicate with PLC or PC
l data records can be exported via USB
l alarm parameter setting, detection range setting, system time setting, communication mode setting and alarm delay setting can be reset by pressing button
l the alarm channel number, alarm concentration & time, and alarm mute function can be directly queried through the menu
l installation method: wall-mounted installation
l when the gas concentration exceeds the pre set first-level (A1 low alarm) alarm value , the buzzer will makes a slightly slow, intermittent sound, the alarm indicator l amp will light on , and the first-level alarm public relay will starts to work
l when the gas concentration exceeds the pre set second -level (A 2high alarm) alarm value , the buzzer will makes a sharp , intermittent sound, the alarm indicator l amp will light on , and the first-level alarm public relay will starts to work
l when the gas detector’ s circuit fail, such as: no signal output from the gas detector, of transmission line drop or the signal output of the gas detector exceeds the measurement range, the buzzer will makes a continuously sound and the alarm indicator l amp will light on
l Data L ogging F unction
