Designed for industrial use

Opto 22 introduced the first analog I/O for a PC-based control system—Optomux—in 1983. We've been making reliable, industrial I/O for analog control ever since.

SNAP analog modules are designed for harsh environments: all are transformer isolated and optically isolated from the field side to the control side. An isolated input module or output module offers channel-to-channel isolation, too.

Analog modules are available in a broad range of signal types:

• Current input and current output (with and without loop sourcing)
• Voltage input and voltage output
• RMS
• Rate
• Temperature (ICTD and thermocouple)
• RTD
• pH/ORP
• Thermistor
• Load cell
• TPO

In addition, special SNAP power input modules are ideal for measuring energy use.

Each SNAP analog module contains 2 to 32 points of I/O—software configurable by point—so a small number of modules can handle a wide range of inputs.

Analog Control

Analog modules monitor, control, and acquire data from a wide assortment of sensors and devices.

Use analog modules for:

• temperature monitoring
• flow control
• valve automation
• pump control
• air pressure control
• drum or tank level control
• and many other similar industrial control applications

All SNAP I/O modules are built in Temecula, California, and tested twice. So reliable, they're guaranteed for life.
