Bullet WirelessHART Adapter
The MACtek Bullet
The Bullet enables existing wired HART field devices from any supplier to communicate with host applications by means of WirelessHART™ technology. The Bullet is installed permanently by wiring it directly to a standard HART field device, or connecting it anywhere on the 4-20mA current loop with a junction box. A wired HART field device retrofitted with the Bullet communicates its analog process variable over the existing wiring to the existing DCS with no wiring changes. The Bullet simultaneously communicates the digital PV and device diagnostic information over the WirelessHART network.
The Bullet can also be installed on a non-smart (analog only) device and will transmit a digital representation of the analog 4-20mA PV to the control room over the WirelessHART™ network which can save labor cost by eliminating manual recording of data.
- Add to existing wired HART-enabled devices to access valuable HART data and device diagnostics
- Use when new measurements are needed but cost of wiring or time is prohibitive
- Upgrade control valves with smart positioners to provide valve health and diagnostic data
- Additional measurements by adding the Bullet to “analog only” devices not connected to the control or asset monitoring systems
- Cost saving Multidrop support for up to 8 devices
- Loop powered option - no battery or other power source required
- Connects directly to HART field device or anywhere on the 4-20 mA loop
- Patent pending StepVolt™ technology sets insertion voltage in steps from 1 to 2.5 volts to optimize trade off between available loop power and wireless communication bandwidth
- Patent pending Direct Power option when local DC power or battery/solar system is available:
- Internal 250 ohm loop current sense resistor provided, configurable by WirelessHART command
- In Direct Power mode, Bullet can switch field device on/off to take periodic readings to save power
- 200+ meters open air range
- Certifications for GP model:
- HART 7.1 Registered with the HART Communication Foundation - fully compliant for communication reliability when the WirelessHART test suite is available
- FCC Part 15, IC, CE
