Fixed alarm controller

SFD-860ⅡThe type of SFD-860II series alarm controller

Using (ARM Cortex -M3) 32 bit high speed industrial control, 12 bit AD conversion chip, faster and more accurate. 

2.8 inch true color display, touch screen control, full Chinese menu, friendly UI design experience.

Has 1000 alarm time records, alarm concentration records,1000 fault and trouble shooting time records , 1000 boot and shutdown time records. Detector capable of shielding failure. The zero point and sensitivity calibration of the intelligent detector can be carried out remotely. The measurement range, unit and sensitivity of each detector can be set up. Built in 5.2AH/12V standby power supply.

Power input: 100 ~ 240 vac 50/60 hz

Measuring range: 0 ~ 10000 (unit value can be set arbitrary)
Signal input: 4 ~ 20 mA signal

Output capacity: output four groups( Intelligent programming combined control ), passive, normally open contact signal.
Power consumption: < 12 w.
Warning: sound and light alarm, digital display.
Temperature range: - 10 ℃ ~ + 45 ℃


Transmission distance: when connected to the gas detector (note: the gas detector working voltage of 12 V ~ 36, a combustible detector largest consumption need 100 mA current, a toxic detector largest consumption need 50 mA current , R loop resistance  

=(V controller stable voltage -v detector minimum operating voltage)/I detector biggest consumption current . According to the formula to calculate the largest connected with combustible gas detector circuit resistance of 120 ohms, and toxicity detector connected biggest circuit resistance of 240 ohms.


With 4 loop detector, for example:
Calculation method: furthest distance = maximum loop resistance ÷ Kilometer loop resistance  ÷  n channel detector








Temperature range: - 40 ℃ to + 70 ℃.
Relative humidity: 15% 95% RH.

Size: 200 x300x80 (mm).
Associated equipment: SFD-860III alarm controller, SFD-2000 system, SFD - 860, SFD - 600 (BA), SFD - 600, SFD - 600 II
