Transform output: 4-20mA (the load <650Ω)1-5V
0-10mA(the load <1000Ω)0-5V
Communication connection: RS232 or RS485
Storage medium: U disk/256M, U disk/512M
*Record: 16 pens
Without U disk, 23.6 days /pen (1 sceond interval) ~15 years /pen (4 minutes interval)
U disk/256M, 256/4× [23.6 days /pen (1 sceond interval) ~15 years /pen (4 minutes interval)]
*Storage time: T=storage capacity/ the sum of the reciprocal of each open channel's record interval; When storage data is temple, the storage capacity also the total storage is 4000× 504.
For example: When the storage data is temple, the open channels are 1, 3, 5, 7, the record interval of every channel is 1second, 5seconds, 10 seconds, 20seconds, then
T= 4000× 504/(1/1+1/5+1/10+1/20)=1493333 seconds=414.8 hours=17.28days.
(note: The total storage is 976× 504 when channels≤ 8)
*cut off protection time: The data can be stored forever when the electricity is cut off for it adopts FLASH MEMORY, it can run accurately when cut off if hard clocks is equipped.
*Power source: Switch power supply 85VAC-264VAC, 50Hz± 1Hz, power consumption 12W
*Ambient temperature: 0-45
*Ambient humidity: 0-85%RH
