Power Solutions
10–30V dc
For locations with power, the 10–30V dc devices offer an easy-to-install solution for sensing
devices.
• 10–30V dc can power more sensors and more types of sensors to obtain the necessary
data.
• The number of sensors powered by the SureCross device is only limited by the number
of I/O points available.
• The Node may be set to high-speed I/O sample and reporting rates for quicker data
collection.
FlexPower™
Banner’s FlexPower technology offers a true wireless solution by allowing most FlexPower
devices to operate using either 10–30V dc, 3.6V lithium D cell batteries, or solar power.
• The FlexPower Node may be powered from 10–30V dc and use an external battery
supply module to provide a battery back-up solution.
• When a FlexPower Node receives 10–30V dc, it operates like a standard 10–30V dc
Node.
• Good applications for FlexPower devices operating from batteries include sensors that
require no or very little power, including dry contacts, RTDs, and thermocouples.
FlexPower with Switched Power
Some FlexPower devices include an internal power supply, called switched power (SP), for
powering sensors that require 5, 10, or 15V power (ideally, 4–20 mA loop-powered sensors).
• To extend battery life, after the sensor takes a reading, the Node shuts down the sensor
to conserve power. To reduce power consumption, slower sample and reporting rates
are used. Faster sample and report rates can be configured, but this will decrease the
battery’s life.
• The FlexPower switched power management system can operate a FlexPower Node and
a sensing device for up to five years on a single lithium D cell.
Internal Battery FlexPower Devices
A few FlexPower devices operate using a 3.6V lithium D cell battery integrated into the
housing. These integrated battery devices:
• Operate only from the battery and cannot use an external power supply
• Are limited in the available I/O because of the limited connectivity
• Can only be powered from the integrated battery
Solar Power Assembly
Banner’s Solar Power Assembly can be used to power up to two radio devices, including a
FlexPower Node, a FlexPower Gateway, or a data radio.
When used with a FlexPower Node and sensors, the Solar Power Assembly can supply
enough power to run most sensors at higher sample and report rates than a single battery can
reasonably support. Rechargeable batteries power the devices while the solar panel recharges
the batteries.
