The sensors are prewired to an included wire bundle, which connects to the Whisker.Block® via an M8 connector. Also included is an internal, on-board, thermistor with +/- 1°C accuracy. By default, readings are taken every five minutes and battery life will last over ten years on the included battery pack.PowerThis Whisker.Block® can be powered internally using a 3.7V, 5.2A-H LiThCl battery pack (10+ years of service life) or 8-24V DC through Connector 1 pin 1. Select variants are equipped with an internal 5V/18V sensor power supply that can provide up to 30mA to external sensors; this is available on pin 1 on both connectors when battery power is used and pin 1 of connector 2 when external DC power is used.RangeIn an unobstructed, outdoor line-of-site environment, the sensor should be able to communicate for more than .5 miles assuming a receiving antenna elevation of 10 feet. If the receiving antenna is raised to 20 feet or more, the range should increase to more than 1 mile. Range performance will degrade if the internal antenna is used; maximum range is achieved with the external antenna.Internal ChannelsThis Whisker.Block® is configured with two (2) internal channels:VDCBattery VoltageAmbient TemperatureExternal ConnectionsThis Whisker.Block® is configured with two (2) external channels:4231Not used (Left)4231Con 1 (Right)ConnectorPinFunctionDescription11Vin(Vout)8-24V Input (Sensor Voltage Out)12Channel 14-20 mA Analog Input13Channel 24-20 mA Analog Input14GroundCircuit groundOrdering InformationPart NumberDescriptionWB1-9-0D-A4A4NNNN-0000-XR4-20 mA Analog Input (x2), 900 MHz, 8-24V Ext DC, External AntennaWB1-9-0D-A4A4NNNN-0000-LR4-20 mA Analog Input (x2), 900 MHz, 8-24V Ext DC, Internal AntennaWB1-9-50-A4A4NNNN-0000-XR4-20 mA Analog Input (x2), 900 MHz, External AntennaWB1-9-50-A4A4NNNN-0000-LR4-20 mA Analog Input (x2), 900 MHz, Internal AntennaWB1-9-10-A4A4NNNN-0000-XR4-20 mA Analog Input (x2), 900 MHz, External AntennaWB1-9-10-A4A4NNNN-0000-LR4-20 mA Analog Input (x2), 900 MHz, Internal Antenna
