Modbus RS485 to USB converter. Used for connecting Modbus sensors using USB connector of Vutlan monitoring units.

Used for monitoring systems: VT900, VT900DC, VT960, VT960DC

The output signal can meet the RS485 standard, the communication distance of more than 1200 meters, the communication load is greater than 30, the baud rate is less than or equal to 19200BPS, by GB/T17626.4 electrical fast transient burst grade III experimental requirements, GB/ T17626.5 surge (impact) immunity level III test request.

Price €109.00

Allows to monitor up to 32 Modbus RTU devices/meters/sensors. Max. a 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 representation for these elements.

It can be used with VT325, VT335S, VT805, VT825 monitoring systems. Installed inside the monitoring unit. Has an internal termination and by default, it is switched ON (if required can be turned off).

The SDM630MCT is a three-phase multifunction DIN-rail meter. It can measure and display the characteristic of 1p2w, 3p3w, and 3p4w supplies, including voltage, current, power, active and reactive energy imported or exported. Energy is measured in terms of kWh, kVarh. Max demand current can be measured over preset periods of up to 60 minutes. In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the meter. The required current inputs are obtained via current transformers. It is easy to connect to any Vutlan monitoring unit via RS-485/Modbus RTU. And the configuration is password protected.
