Technical Specifications
Dimensions:
160mm x 130mm x 67mm (6.30in x 5.11in x 2.64in)
(Excluding glands)
Mass:
1450g (3.19lb) with gel-cell battery fitted.
Power Supply:
Internal 12V @ 0.8A/Hr rechargeable sealed lead acid battery. Can also connect an
external regulated 12V dc power supply or rechargeable sealed lead-acid battery.
Charger Supply:
External 15-30Vdc supply. Supports a directly connected solar panel (no regulator).
Power Consumption:
Less than 6mA @ 12V in idle mode. Actual current consumption is dependent on
power management mode, wireless modem state and I/O configuration.
Comms Interfaces:
1x RS232 DB9, 38,400 bps, DTE configuration.
1x Integral multi-band wireless modem or
1x Plug-in comms adaptor E.g. Ethernet, satellite etc. Requires PCB Rev 1.2+
Digital I/O:
4 x Digital Inputs/Outputs. Each channel configurable as either an input or output.
Digital Input Mode:
- 30Vdc maximum input, switch to 0Vdc to activate.
- Link selectable for either mechanical (<20Hz) or electronic (<5kHz) switching.
Digital Output Mode:
When set for output, the channel can be either:
- Switched 12V out (max 100mA) or
- Open-drain pull-down (max 100mA @ 30V)
Analogue I/O:
4 x 16 bit uni-polar analogue inputs. Range 0 – 5.000V. Input impedance 98kΩ.
Referenced to 0V common. Internal measurements available for monitoring are:
Battery Voltage
Supply Voltage
Internal Temperature (
C or
F)
Received Signal Strength (RSSI or RSCP)
Link selectable for either voltage (0-5V) or current (0-20mA) mode. Integral
current mode resistor value 100R.
SDI-12 Interface:
SDI-12 hardware interface that fully complies with the SDI-12 electrical standard.
Software support to SDI-12 standard 1.3.
Logging Memory:
Non-volatile 8MB flash storage of 1,085,476 time/date stamped data points. Circular
buffer mode (overwrites oldest data when memory full).
A typical site with 2 parameters logged every 15 minutes plus battery voltage logged
hourly will give 3.3 years of storage before data overwrite occurs.
Audio Memory:
iRIS 350FXV only
. Non-volatile 8MB flash storage of PCM audio files. Total
cumulative audio playtime 12 minutes at 11.025kHz sampling rate.
Clock/Calendar:
Non-volatile with user replaceable lithium back-up battery module. Accurate to +/-
20 seconds / month
