AD-LU 320 GVD

Description

The digital power measuring transducer AD-LU 320 GVD measures all quantities of the power-network (current, voltage, energy, harmonics, phase angle, active power, reactive power, apparent power) and converts these measuring values onto two freely scalable analogue outputs. The unit is therefore optimal suitable for integration in energy management systems. For measuring of high voltages or high currents, external transformers can be connected in series at any time. All measuring ranges and outputs can be freely parameterized. This can be carried out via the optional operating modul AD-VarioControl or via the programming software AD-Studio. The LEDs at the front signals the operating condition. The compact type of construction and the high performance ability with simultaneous low energy consumption allows usage in almost any application.

Modbus Communication

The optional AD-VarioConnect operating module has an RS-485 interface. The data is transferred via the Modbus RTU protocol, the AD-VarioConnect operating module represents a Modbus slave. Communication takes place according to the master-slave procedure and starts with a request from the master, e.g. from a PLC or a PC. Each bus participant must have a unique address. If a slave detects that its address has been addressed by the master, the slave always sends an answer. The slaves never communicate with each other. They are also not able to start a communication with the master.
The Modbus master can read out the individual registers of the AD-LU 320 GVD via the addresses.
The default standard data format is 19200,e,8,1 with slave address 1. These settings can be changed via the AD-VarioConnect operating module.
