When using the BULLET, no additional battery is needed. Connection of HART devices is possible as well as connection of 4 mA … 20 mA devices, enabling flexible adaptation to changing application requirements.
The BULLET supplies itself with energy from the 4 mA … 20 mA current loop, using a special technology called “StepVolt”. This technology allows users to set insertion voltage from 1 V to 2.5 V in order to optimize the usage of available loop power and wireless communication bandwidth.
The BULLET provides reliable performance even under worst case low-current conditions, where there is very little power available – when using transmitters on very long cable runs or with intrinsically safe barriers. In scenarios where more power is available, the BULLET provides a higher amount of WirelessHART packets per second, leading to an increased performance of the overall WirelessHART network.
