AD-VarioControl, AD-VarioConnect


The removable control modules AD-VarioControl are used to display measured values of a base device (transmitter, isolation amplifiers ...) with a relevant interface. After plugging in, which is also possible during operation of the base device without restrictions, the basic device is automatically read out and the corresponding measured value is displayed. In addition to the display function, access to the parameters and controller functions of the basic device is also possible. The parameter settings can be loaded into the control panel using the backup function and can be restored on a different base device of the same type.
Establishment of a transmitter is usually necessary only once in the operating period of a device, therefore a display and operating elements are not permanently necessary for each device. By using the AD-VarioControl in connection with compatible basic equipment, operating elements and displays on each individual device can be dispensed with. This way, the installed devices are tamper-proof and more cost-effective.
The AD-VarioConnect has a fieldbus interface with the protocol Modbus-RTU via RS485. All measured values of the basic units are available above this.
