Q. How do I connect sensors to the VMB4AN?
A. Up to 4 sensors can be connected to the VMB4AN using the "analog in" connections. For resistance, 0-10V and frequency sensors connect one wire to the COM input and the other to the 1, 2, 3 or 4 input. For current sensors (0-20mA), connect the + of the sensor to the + (power supply) of the VMB4AN, and the - of the sensor to input 1, 2, 3 or 4.
The type of each sensor (resistance, 0-10V, 0-20mA or frequency) is configured using Velbuslink.
If the sensor needs a 24V DC power supply, this can also be supplied by the VMB4AN using the leftmost 4 connections.
If the sensor has 3 wires, 2 of them (typically those that have the same color) have to be connected together.
