I/O module for RTDs

Opto 22 adds new 1,000 ohm RTD temperature sensing I/O module for its SNAP PAC family.

Opto 22 has released its new SNAP-AIRTD-1K, a two-channel, isolated analog input module for use with 1,000 ohm platinum RTDs.Opto 22 has released its new SNAP-AIRTD-1K, a two-channel, isolated analog input module for use with 1,000 ohm platinum RTDs (resistance temperature detectors). With the SNAP-AIRTD-1K, Opto 22's line of SNAP I/O modules now includes RTD input modules for use with 10 ohm copper, 100 ohm platinum, and 1,000 ohm platinum probes.

The SNAP-AIRTD-1K module provides two channels of analog temperature input, with a nominal input temperature range of -200 to 850 °C (-328 to 1,562 °F) and an input range of 0-4,000 ohms. The module has an average resolution of 0.042 °C (0.16 ohms). Used primarily with RTD probes to provide temperature inputs, the module can also be used for making high-resolution resistance measurements.

1000 ohm platinum RTD probes are used by engineers and technicians to measure temperatures precisely in industrial furnace and refrigeration applications, HVAC systems, autoclaves, or any application requiring accurate measurement over a wide temperature range. The SNAP-AIRTD-1K module is used in systems based on Opto 22's SNAP PAC (programmable automation controller), and also in SNAP Ethernet I/O systems used for PC-based control applications.

The module is guaranteed for life, is transformer isolated, and like all Opto 22 SNAP I/O modules, is optically isolated from the equipment and devices it connects to, as well as from other modules on a shared I/O rack.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
