Replacement Box SE-402-701

After more than 25 years of successful use and more than 2,500 units delivered, we had to discontinue production some time ago due to components that are no longer available.
Spare parts and repairs are currently still possible for devices that were delivered in the last 10 years. By stocking electronic cards and components, we can still guarantee spare parts and repairs.
Due to the high quality of our products, program controllers are often in use for more than 20 years.
In order to guarantee the function and future security of your plant, we recommend for devices, which are 15 years and older (SN-No. under 21000), a change to current device technology. To be able to offer you the changeover to the latest technology as simply, quickly and cost-effectively as possible, we have developed a conversion concept for this purpose.
The requirement is that your SE-402 program controller is still functional so that the configuration data can be read out.
The read-out configuration is transferred by us into the configuration compatible and newly developed SE-701. Afterwards the controller can be installed and operated in your system again.
Since the device and function principle is almost identical, you can quickly resume operation and operation of your installation without much effort.

Please contact our sales department for an non-binding offer or in case of queries.
