4-Channel RTD/CT Wireless Sensor Node

The SN90RC-4 is a battery-powered wireless sensor node that provides support for two 100 ohm Platinum RTD inputs, two current transformer inputs and two switch inputs (many other sensor configurations are available, contact Murata for details). Connectivity is provided through a 900 MHz Frequency Hopping Spread Spectrum (FHSS) wireless connection, making use of the companion LG90E Ethernet gateway or LG90C cellular gateway. The unique low-power architecture used in the SN90RC-4 provides years of battery operation. Sensor data and battery status are automatically transmitted based on user-configurable conditions, simplifying application software design. The wireless sensor node can be configured over-the-air or through its serial port.
