Active RFID Tags: Features, Specifications, and Deployment Guidelines

These tags report their own unique ID and a portion of the 4-20 mA loop current value once every 10 seconds using RF

Code’s patented communication protocol; this results in three (3) sensor readings per minute.

4-20 mA supported specifications:

 1.25 uA resolution

 ±0.5% accuracy

 100 ohm resistance

 Loop supply not included; the sensor must provide the power (or a separate power supply is required)

The R180 ships with an 8-foot 24 AWG stranded cable that can be cut to fit or spliced.

Powered by three (3) field-replaceable coin cell batteries, the R180 tag will perform reliably in an operating temperature

range from -20 to +70 degrees Celsius. R180 tag enclosures are impact resistant and temperature stable. The R180 tag

operates with a low duty cycle that translates to long battery life (typically > 5 years). Featuring a low-battery alert, the

tag will continue to report 4-20 mA data for at least three months following this alert.

Features:

 4-20 mA wired interface via replaceable 8-foot insulated cable (24 AWG stranded)

 Adhesive mounting options for the tag and cable, making it easy to install the tag for maximum RF propagation

 Tag relays 4-20 mA payloads for upstream compiling and interpretation in the software stack

 Standard reporting interval of 3x per minute; optional custom firmware configurations to adjust communication

and beacon rates for specific applications

 Estimated 5-year battery life with user-accessible / replaceable coin cell batteries

 Modular cable that is easy to install and to cut to length, with a binding connector to reduce the chance for

accidental unplugging

Mounting and Configuring R180 Tags

When mounting R180 4-20mA Sensor Tag, follow these instructions and guidelines:

1. Mount the R180 tag using provided adhesive pads or by securing with screws or zip-ties (not provided). Attach

the tag to the top of equipment to ensure a clear RF signal path in metal-dense environments.

2. Optionally cut the 8 ft. cable to desired length.

3. Secure wiring using zip-ties to provide a strain-relief and prevent inadvertent unplugging of the sensor.
