Control panel: Control panel with touch panel H 3700 for retort furnaces

This control and regulation system with touch panel H3700 is a quality product that ensures reliable operation for many years.

All functions and the entire process are stored and displayed graphically in a clear manner.
The data can be read and processed via various interfaces (USB, Ethernet TCI/IP, MPI, Profibus) from the PC or other customer-side programs.
All set and actual values can be stored on a CF card and read out using the appropriate card reader.
With extensive accessories, even complicated heat treatment processes can be realized.
Control and regulation system as well as the operating elements are integrated into the furnace housing.
The temperature control and furnace control is implemented via an SPS (Siemens Simatic S7).

The visualization and operation of the furnace functions is a H 3700 touch panel (touch panel with 12” color display and 256 colors) for simple and clear operation.

Additional functions:
Acoustic and optical signal of a fault message.
Programmable start time.
