iRIS 220 / iRIS 320, V1.19 User Guide
2.7 Technical Specifications – iRIS 320 / iRIS 320V
Dimensions: 117mm x 162mm x 67mm (4.60in x 6.37in x 2.64in)
(Excluding glands and mounting plate)
Mass: 1580g (3.48lb)
Power Supply: Internal 12V @ 0.8A/Hr rechargeable sealed lead acid battery. Can also connect
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 3mA @ 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 dual-band (900/1800MHz) GSM/GPRS modem or
Integral single-band (1900MHz) GSM/GPRS modem or
Integral CDMA/CDMA-1X modem.
Digital I/O: 2 x Digital Inputs
- 30Vdc maximum input, switch to 0Vdc to activate.
- Link selectable for either mechanical (<20Hz) or electronic (<5kHz) switching.
2 x Digital Outputs
- 1 x Switched 12V out (max 300mA)
- 1 x Open-drain pull-down (max 300mA @ 30V)
Analog I/O: 4 x 12 bit uni-polar Analog inputs. Range 0-5000mV. 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)
SDI-12 Interface: SDI-12 hardware interface that fully complies with the SDI-12 electrical standard.
Software support to SDI-12 standard 1.2.
Logging Memory: Non-volatile 2MB flash storage of 262,144 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 320V only. Non-volatile 2MB flash storage of PCM audio files. Total
cumulative playtime 3 minutes at 11.025kHz sampling rate.
Clock/Calendar: Non-volatile with integral lithium back-up battery. Y2K compliant with leap year
recognition. Accurate to +/-20 secs month, trimmable via a configuration register.
Mounting: 4 x M4 (3/16”) blind mounting holes in rear of case. Mounting plate supplied as
standard accessory for wall or panel installation.
2 x 16mm (¾”) compression glands for power supply and I/O cabling access.
1 x 25mm (1”) compression gland for antenna / RF cable access
Front secured by three M5 Allen Key® screws. The two (left-hand) screws act as
hinge links. The third (right-hand) screw can be locked with a tamper-proof wire seal.
Environmental: Storage Temperature: -20°C - +85°C. (-4°F - +185°F)
Operating Temperature: -10°C - +70°C. (14°F - +158°F)
Enclosure sealed to IP65 with gasket and glands.
