Product Description
The DS-4483 datalogger is supplied standard with keypad and 2x40 display, 1Mb storage memory, a standard RS232 and two dedicated serial instrumentation ports for connection to SDI12 and synchronous serial instruments. The unit is fully programmable, has an on-board real-time clock and is Year 2000 compliant. Shutdown and sleep modes will keep the power requirements to a minimum so that the unit can be used for solar powered sites.
Power Supply 12V - 13.8V DC (nominal rating) Maximum 15V - over voltage and reverse polarity protected.
Quiescent Power Loading 19 mA - all relay and control outputs off, SDI-12 port idle, backlight off (current drawn by external equipment connected to the datalogger is not included)
Physical Dimensions 226mm H x 117mm W x 38mm D
Environmental Limits 0oC - +70oC, 5% to 95%RH (non-condensing). -25oC - +70oC available on special request
Weight 1250 gms
Mounting Side mounting slotted holes (4mm flat head screws) or DIN Rail feet.
Digital I/O 2x Standard general purpose digital inputs 0-12V DC IN or a clean contact
2x High speed pulse inputs (5kHz) 0-12V DC
1x Uncommitted control relay SPDT rated 10A - typically used for radio switching
2x Open drain pull-down sinking outputs max 500mA @ 30V
2x 12V sourcing outputs max 100mA @ 12V
All outputs short circuit proof with auto-reset semiconductor fusing.
Analogue I/O 8 x 12 bit unipolar analogue inputs (can be paired as differential inputs). Software controlled base range on a per channel basis. Current and voltage mode settable by installingexternal resistors.
