Thermocouple analog modules provide a single channel of transformer and

optically- isolated temperature-to-digital conversion. The modules offer wide nominal

input range and special over/under range capabilities. The modules also include

complete electrical channel-to-channel isolation that eliminates troublesome ground

loop problems. Modules plug into an Opto 22 Modular controller or an analog I/O

brick and are secured by a captive screw. The field connections are made through four

contacts to the terminal strip located on the brick base or Modular Controller I/O

board.

NOTE: Any system using analog sensors and input modules should be calibrated

annually for analog signals. To do so, use OptoControl commands “Calculate and Set

Analog Offset” and “Calculate and Set Analog Gain.”

Products

Opto 22 produces a broad array of reliable, flexible hardware and

software

products for industrial automation, remote monitoring, enterprise

data acquisition, and machine-to-machine (M2M) applications.

SNAP Ethernet Systems

Based on the Internet Protocol (IP), SNAP Ethernet systems offer

flexibility in their network connectivity and in the software applications

they work with. The physical network may be a wired Ethernet network, a

cellular wireless network, or a modem. A wide variety of software

applications can exchange data with SNAP Ethernet systems, including:

• Opto 22’s own ioProject™ suite of control and HMI software

• Manufacturing resource planning (MRP), enterprise management,

and other enterprise systems

• Human-machine interfaces (HMIs)

• Databases

• Email systems

• OPC client software

• Custom applications

• Modbus/TCP software and hardware.

SNAP Ethernet system hardware consists of controllers and I/O units.

Controllers provide central control and data distribution. I/O units provide

local connection to sensors and equipment.

SNAP OEM Systems

Opto 22 SNAP OEM I/O systems are highly configurable, programmable

processors intended for OEMs, IT professionals, and others who need to

use custom software with Opto 22 SNAP I/O modules.

Linux® applications running on these systems

can read and write to analog, simple digital, and serial

I/O points on SNAP I/O modules using easily

implemented file-based operations. Applications can

be developed using several common development

tools and environments, including C or C++, Java,

and shell scripts.

M2M Systems

Machine-to-machine (M2M) systems connect your business computer

systems to the machines, devices, and environments you want to monitor,

control, or collect data from. M2M systems often use wireless cellular

communications to link remote facilities to central systems over the Internet,

or to provide monitoring and control capability via a cellular phone.

Opto 22’s Nvio™ systems include everything you need for M2M—

interface and communications hardware, data service plan, and

Web portal—in one easy-to-use package. Visit nvio.opto22.com for

more information.
