2.6 Technical Specifications – iRIS 220
Dimensions: 100mm x 172mm x 40mm (3.93in x 6.77in x 1.57in)
(Excluding connectors)
Mass: 380g (13.4oz)
Power Supply: External regulated 12V dc power supply or rechargeable sealed lead-acid battery.
Charger Source - External 15-30V dc supply. Supports a directly connected solar
panel (no regulator required).
Power Consumption: Less than 3mA @ 12V in idle mode and full power save mode selected.
Actual current consumption is dependent on power management mode, wireless
modem state and I/O configuration.
Comms Interfaces: 1x RS232 DB9, 38400 bps, DTE configuration.
1x Integral dual-band (900/1800MHz) GSM/GPRS modem or
Integral single-band (1900MHz) GSM/GPRS modem or
Integral CDMA/CDMA-X 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 Indication (RSSI)
Logging Memory: Non-volatile 2MB flash storage of 262,144 time/date stamped data points. Circular
buffer mode (overwrites oldest data when memory is 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.
Clock/Calendar: Non-volatile with integral lithium back-up battery. Leap year recognition. Accurate to
+/-20 secs month, trimmable via a configuration register.
Mounting: 4 x M4 (3/16”) mounting holes at ends of case.
Environmental: Storage Temperature: -20°C - +85°C. (-4°F - +185°F)
Operating Temperature: -10°C - +70°C. (14°F - +158°F)
