Communication - industrial transmitters (VFI, RPI, DPI v.1 & v.2)

Grundfos Direct Sensors™ (industrial) come with various signals.

In the basic version, an analogue signal is provided giving a 0-10 VDC ratiometric output or 4..20mA signal from a 12-30 VDC standard power supply.

 

Communication - standard sensors (VFS, RPS, DPS)

Grundfos Direct Sensors™ (standard) come with various signals. In the basic version, an analogue signal is provided giving a 0.5-3.5 VDC ratiometric output signal from a 5 VDC supply.

On top of the DC signal lies digital information, which thru a recommended interface enables the control manufacturer to read the sensor’s digital context.

A customized version for high volume OEM partners, provides a proprietary BUS protocol option.

Analogue:

  • Ratiometric output secures independences from power supply.
  • Low voltage solution for low power consumption.
  • For cost-effective controls.

Digital:

  • A simplified RS232 signal from the sensor enables intelligent controls.
  • RS232 is the most common digital signal overall.
  • Enables TTL connection in a very cost-effective way.

BUS:

  • The V-BUS®;enables whole new options when using Grundfos Direct Sensors™.
  • Easy-setup of multi node sensor networks.
  • Multitude of different RESOL® control solutions. The RESOL V-BUS®;is a registered trademark belonging to RESOL-Elektronische Regelungen GmbH.
