Analog I/O Modules isolate connected field devices.
Press Release Summary:
Dual-channel modules SNAP-AIARMS-i and SNAP-AIVRMS-i suit applications involving ac/dc current and voltage measurement, respectively. Featuring 2 isolated input channels with -1 to +1 mA range, SNAP-AIMA2-i is used for monitoring very low currents in µA range. Module SNAP-AOA-23-iSRC, which features built-in, isolated loop sourcing, is used to output current values to industrial devices. This unit provides 2 channels of current output with 4-20 mA range.

Opto 22 Introduces New Isolated Analog Modules
Temecula, CA - December 20, 2005 - Opto 22, a developer and manufacturer of hardware and software for industrial automation, remote monitoring, data acquisition, and machine-to-machine (M2M) applications, has introduced four new isolated analog modules:
SNAP-AIARMS-i, used for applications involving AC/DC current measurement; SNAP-AIVRMS-i,
used for applications involving AC/DC voltage measurement; SNAP-AIMA2-i, used for monitoring very low currents; and SNAP-AOA-23-iSRC, which features built-in, isolated loop sourcing and is used to output current values to industrial devices.
"These new analog I/O modules offer full isolation between field devices connected to the same module," states Tom Edwards, Senior Application Engineer at Opto 22. "This electrical isolation eliminates the possibility of any damage resulting from differing operating voltages for the connected devices, and protects against damage to devices that may share a module with an overloaded or otherwise malfunctioning device. Also, the built-in, isolated loop sourcing on the SNAP-AOA-23-iSRC can significantly reduce troublesome ground loops when installing 4-20 mA instrumentation."
The SNAP-AIARMS-i offers two channels of 0-10 amp RMS AC/DC input and is perfectly suited for the 5-amp secondary input of current transformers used to monitor AC line current in factory power distribution centers. In these types of applications, the SNAP-AIARMS-i enables early detection of spikes in the facility's electrical consumption, often due to malfunctioning compressors, failed bearings or other components.
The SNAP-AIVRMS-i provides two individually isolated channels of AC or DC input with a range of 0 to 250 AC/DC volts. It is ideal for monitoring the commonly found 120/240-volt AC and 12/24/48-volt DC system voltages to powered equipment and the process voltages of that equipment as it operates.
The SNAP-AIMA2-i provides two isolated input channels with a range of -1 to +1 milliamps. It is best suited for measuring very low currents in the microampere range.
The SNAP-AOA-23-iSRC provides two channels of current output with a range of 4 to 20 milliamps, and includes built-in, isolated current loop sourcing which saves instrumentation technicians' time and the costs associated with providing required isolated external loop power. "Users of Opto 22's popular mistic family of I/O systems-developed in the early 1990's-have found loop-sourcing so valuable, and now it's available in SNAP I/O," explains Edwards.
The SNAP-AOA-23-iSRC's loop sources are internally connected to the individual outputs. Additionally, the two channels and their loop sources share no field connections and are isolated from each other. Each loop source is also current limited so that an external fault on one loop will not affect the other.
All of these new modules are part of Opto 22's flagship SNAP Ethernet systems family and are fully supported by ioProject(TM) Basic and ioProject Professional, comprehensive software suites that include control programming, debugging, human-machine interface development, OPC connectivity, and utilities.
The modules are designed for use with Opto 22 SNAP B-series mounting racks in control system architectures with SNAP Ultimate, SNAP Ethernet, or SNAP Simple brains as well as the recently introduced SNAP PAC-R and SNAP PAC-S programmable automation controllers.
The SNAP-AIARMS-i, SNAP-AIVRMS-i, SNAP-AIMA2-i, and SNAP-AOA-23-iSRC (available now through Opto 22 authorized distributors, partners, and system integrators, or through the Opto 22 website) are priced as follows:
o SNAP-AIARMS-i - $265 USD
o SNAP-AIVRMS-i - $265 USD
o SNAP-AIMA2- i - $265 USD
o SNAP-AOA-23-iSRC - $265 USD
