VPI VISY-Power Interface
●For the sending of commands to the sensors, the VPI supports two protocols*. The response is assigned and forwarded to the individual sensor terminals.
●Up to 1,024 sensors can be connected to 32 VPIs. The sensors require a connection to the VPI. The installation location for the VPI must be outside the potentially explosive atmosphere.
●The VPI is designed for DIN carrier rail installation and has eight intrinsically safe sensor terminals.
●Up to 32 VPIs can be circuited in parallel, depending on the quantity of sensors to be connected.
●Features of the FAFNIR technology
■8 intrinsically safe sensor terminals per VPI
■Connection of max. 32 VPIs in parallel possible = 256 sensor terminals
■One sensor terminal supports the connection of up to 4 different VISY sensors
■Intrinsically safe power supply
■Passive communication via RS485
■Supply to VPI by commercially available power supply unit possible
■Two VPIs can be connected to one FAFNIR VPI-Supply (power supply unit)
■Easy DIN mounting rail installation, no additional enclosure required
■Maintenance-free
