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 98k. 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.
