Function and purpose

It is an extension PCB board and should be purchased separately.

Allows to monitor up to 32 Modbus RTU devices/meters/sensors. The maximum distance of a daisy chain is up to 1000 meters. Each metered value of a Modbus device is addressed individually using input registers and is shown by the system as virtual sensors. You can configure thresholds and icon representations for these elements.

It can be used with VT335t, VT336t, VT825t, and VT855t monitoring systems. A slot PCB board can be inserted inside the monitoring unit while the unit is in operation. Has an internal termination and by default, it is switched ON (if required can be turned off).
