SN90R420-4

The SN90R420-4 is a battery-powered wireless sensor node that provides support for two 100 ohm Platinum RTD inputs, two 4-20 mA inputs and two switch inputs (many other sensor configurations are available, contact Muratafor 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 SN90- R420-4 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.
