Opto 22 adds new RTD temperature sensing I/O module

Opto 22 Snap-AIRTD-10 is a two-channel analog input module used to monitor temperature with RTDs.

Opto 22 Snap-AIRTD-10 is a two-channel analog input module to monitor temperature via RTDs.

Opto 22, developer and manufacturer of the programmable automation controllers, I/O, and accessories, has released the Snap-AIRTD-10, a two-channel analog input module used to monitor temperature via connection to copper resistance temperature detectors (RTDs.)

The Snap-AIRTD-10 provides two channels of analog temperature input from 10-ohm copper RTDs, which makes it well-suited for deployment in older installations. The module has an input range of -180 °C to +260 °C (-292 °F to +500 °F) and can also be used for 0-25 ohms resistance measurements. With its wide input temperature range, high over range limits for RTD input, and small footprint, the module will prove most useful in water treatment, refrigeration, thermoforming, curing, autoclaving, refining, PID loop control, welding, and other temperature monitoring applications that require high resolution measurements with minimal drift. Development of the 10-ohm Snap-AIRTD-10 nicely complements the input module, which accepts 100-ohm platinum RTD inputs. The addition of the Snap-AIRTD-10 also expands Opto 22’s line of multi-channel analog input modules for interfacing to RTDs, thermocouples, ICTDs, thermistors, and infrared sensors for remote monitoring and data acquisition. www.opto22.com
