Introducing NCD’s Long Range Industrial IoT Wireless 4-20mA Current Receiver, boasting up to a 2 Mile range using a wireless mesh networking architecture. It incorporates a High resolution 16-bit ADC that samples 4-20mA analog inputs at user defined intervals and transmits the result to remote modems and gateways. Between samples, this device enters a ultra-low power sleep mode to minimize power consumption. This Industrial IoT Wireless 4-20mA Current Receiver has an additional feature of detecting change in current every 7 seconds (user configurable) and sending out ADC samples if the change in current is greater than 10% (user configurable). Both features work simultaneously to support multiple application areas in one package.
This Industrial IoT Wireless 4-20mA Current Loop Receiver has on board 16V buck boost power supply, thus eliminates requirement of external power supply. This power supply is used to power up the external 4-20mA sensor. This device can be used with any 2 wire 4-20mA sensor/device into a wireless nodes.
Figure 1: Device Overview
The Status LED is used to indicate errors or other sensor diagnostics.
LED blinks once – Message was sent successfully and no error in last sensor read as well in data transmission.
LED blinks twice and then one more time – Message was sent successfully but there was an error in last sensor read.
LED blinks thrice – MCU is having issue communicating with the radio module.

Warning!Make sure you wire you probe correctly as per the instruction below, otherwise you risk damaging the probe and/or the sensor.×
This Sensor has two power options:
Note!The L91 Batteries are non-rechargeable Li-Ion batteries.×
While changing the batteries:
The Truth About Battery Life!Under the best of circumstances, the best non-rechargeable batteries commonly available today are limited to a 10 year non-working shelf life in a room temperature environment. Factors such as actual usage, temperature, and humidity will impact the working life. Be wary of any battery claims in excess of 10 years, as this would only apply to the most exotic and expensive batteries that are not commonly available. Also note that most battery chemistries are not rated for use in extreme temperatures. NCD only uses the best Non-Rechargeable Lithium batteries available today, which are also rated for use in extreme temperatures and have been tested by our customers in light radioactive environments. Lithium batteries offer a 10 year maximum expected shelf life due to limitations of battery technology. NCD will never rate sensor life beyond the rated shelf life of the best batteries available today, which is currently 10 years.×
