Modbus junction box

The Modbus junction box is a real time saver.You can create a daisy chain of VPFlowScopes without mixing up the wires. The Modbus junction box also includes termination and biasing for the RS485 connection. A LED indicator is available which tells you that the minimum voltage (12VDC) is met.

Electrical Installation

The VPFlowScope connection terminal houses the connections of the trunk line and additional inputs for the 4-20mA output from the VPFlowScope. A 4-20mA and return connector have been added to extract the 4-20mA signal. See the picture below for the terminal layout.
