We are pleased to announce that the VPFlowScope electronics platform has been upgraded providing more robust protection against static discharges and short-circuiting. We implemented a new, ultra-robust Modbus transceiver circuit, which can hold up to ±60V on A and B lines. It can also allow a larger common mode range of ±24 Volts, which makes biasing of your RS485 network less critical. This transceiver was already in use in the VPFlowScope M and has now been integrated into the complete VPFlowScope product line, including the VPFlowScope Probe, DP, and In-line.

Background
In many industrial devices, for example, compressor controllers and sensors, RS485 transceivers are easily blown by static discharges, especially when connecting wires for the first time without any protection. Therefore, static protection is very important. We also experienced that one of the most common wiring errors is to reverse data and power lines. Connecting the 24V power supply across the data lines of any traditional RS485 port will result in the transceiver chip going up in smoke, which means the end of your VPFlowScope.
All your VPFlowScope products are now protected with the new integrated overvoltage protection. The new transceiver will protect your VPFlowScope against incorrect connection to the 24V power commonly found in building automation installations, and the data lines will withstand connection to 24V power indefinitely. The protection is rated for a maximum of ±60V.
At VPInstruments, we continuously strive to improve the quality of our products, to make them more reliable, and easier to use over time. That’s also a way to provide easy insight into energy flows.
