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 98k￿. 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)
