AD-TV 400 GVD

Description

The isolation amplifier AD-TV 400 GVD serves the galvanic separation of analogue signals and of transmitter signals. When a 2-wire transmitter is connected, this will be supplied directly via a galvanically separated and current-limited supply voltage. All measuring ranges and outputs can be freely parameterized. This can be carried out via the optional operating panel AD-VarioControl or via the programming software AD-Studio. The wide bipolar input measuring range makes this buffer amplifier into the universal type for almost all applications in the area of standard signals and beyond. Due to its current-sinking output, transmitter signals can also be separated or converted. All supply ranges are covered with the wide range power pack.

AD-PC: Communication interface for configuration by a PC

Communication interface for VarioControl

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-TV 400 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.
