Introduction
The Opto 22 SNAP-IT
™
panel-mount unit is a packaged solution for attaching electrical, electronic,
and mechanical devices to an Ethernet network. Once attached to a network through the SNAP-IT
unit, these devices can be monitored and controlled from anywhere in the world.
The panel-mount unit comes in multiple models.
The SNAP-IT-PM-R1ADS and SNAP-IT-PM-R2ADS include a SNAP PAC R-series rack-mounted
controller, a 12-module mounting rack, a power supply, and a 24 V loop power supply, all built in and
pre-wired. The controller provides I/O processing, communications, and programming capability.
With this unit you receive the PAC Project Basic software suite, which includes control programming,
human-machine interface (HMI) development, and configuration software.
Other models provide a modem for remote communication, or offer a SNAP PAC brain instead of a
controller. The brain does not include programming capability, but provides local intelligence for I/O
processing and communications.
With any SNAP-IT model, you add the analog, digital, and
special-purpose input/output (I/O) modules necessary
for your application.
Packaged in a sturdy NEMA 3R metal housing for
mounting on walls or equipment, SNAP-IT units are
suitable for use in indoor or outdoor environments.
Typical applications include monitoring and controlling
facilities, machines for manufacturing and processing,
communication towers, tanks, pipelines, and other
equipment. For example, you can:
• Detect machine jams and shutdowns
• Control processes
• Report production counts
• Track machine throughput to plan preventative maintenance
• Manage temperature, humidity, and security in facilities
• Control fans, lights, pumps, and compressors
