Applicable sensors: No.7910-00 Wind speed and direction sensor (W639-ED1)
Input signal: Wind direction: 0 to 360°/0 to 1VDC
Wind speed: pulse output (60 pulses per one propeller rotation)
Indication: Wind direction: red LED 16 pcs. (16 azimuth)
Wind speed: red 7 segments LED 4 digits, height of character (upper and lower): 14.2mm
Display elements: Wind direction: instantaneous or mean value (average of 10 minutes): changed by a button setting
Wind speed: instantaneous value and mean value (average of 10 minutes)
Display range: Wind direction: 0 to 360° (16 azimuth)
Wind speed: 0.00 to 99.9m/s
Sampling interval: ~1 sec. (lighting hold time)
Alarm:
- Wind direction:
+ Instantaneous or mean
+ Alarm setting range: two sections in 0 to 359°
- Wind speed:
+ Instantaneous or mean
+ Alarm setting range: 5 to 90m/s (Mutual setting in alarm 1, alarm 2 and alarm 3)
Alarm output:
- Wind direction:
+ No voltage make contact , Contact capacity: 24VDC, 1A (resistance load) * the signal of the alarm contact is output from alarm 3
+ LEDs of 16 azimuth: LED blinks to indicate the alarm setting section
- Wind speed- alarm 1:
+ No voltage make contact: contact capacity: 24VCD, 1A (resistance load)
+ Green LED (slow blinks)
+ Buzzer (long intermittent sound)
- Wind speed-alarm 2
+ No voltage make contact Contact capacity: 24VDC 1A (resistance load)
+ Yellow LED blinks (fast blinks)
+ Buzzer sound (short intermittent sound)
- Wind speed-alarm 3:
+ No voltage make contact; Contact capacity 24VDC, 1A (resistance load)
+ Red LED blinks (continuous blinks)
+ Buzzer sound (continuous sound)
* If the alarm sound in wind direction is set, the alarm 3 is not usable for wind speed
Alarm reset: When contact output and wind speed value of LED display are smaller than the value of the alarm setting / the value of wind direction is out of the range to be set.
Buzzer sound (continuous sound): by the key operation of the front panel
Operation ambient: 0 to 50°C, less than 90%rh (no condensing)
Remote distance: approx. 300m max. (in use of CVVS 1.25mm2 cable)
Case: Steel plate, desk top type (rubber foot, tilting stand)
Power requirements: 100VAC±10%, 50/60Hz, approx. 20VA
Dimensions: (W)200×(H)110×(D)200mm
Weight: ~3.5kg
