SNAP Analog I/O

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, right out of the box. Some modules also offer channel-to-channel isolation.

Analog modules are available in a broad range of signal types. Each module contains 1 to 32 channels (points), which can be individually configured. Signal types include:

• 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
• Power monitoring

 

 

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
