Interfaces

The 1-wire industrial bus has been around since the end of the 1980s => proven technology. Nevertheless, the bus is highly modern. We have extended the existing bus with a plug and play layer and applied for a patent for this => Auto-E-Connect.

Alarm loops are very often used in IT and industry. They are used to forward faulty states of devices to signalling devices. ECO controllers have alarm inputs and outputs.

In the field of building automation (smart building), there is often a need to detect 230V AC signals. This also applies to the IoT sector. It is about binary input for the 0/1 queries. We have this type of inputs in our portfolio.

In industry, the 24V binary input is the standard for 0/1 queries. Of course, we offer these inputs in many sensors and controllers.

For the electrical connection of analog sensors, 0-10V DC interfaces are still often used today. Measured values are converted proportionally into a voltage between 0-10V. On the receiver side is converted back.

The current interface or also called current loop interface (4-20mA) for analog values has been around for a long time. It is mostly used in industrial environments where high noise levels have to be expected.

Counter or pulse inputs, also called S0 input, are often used for the acquisition of energy consumption. As an example for electricity meters, water and gas meters. Pulse inputs are also used in the field of wind sensors.

By relay almost all types of digital outputs can be switched. It should be noted that most relays can be operated up to 30VDC or 230VAC. For inductive and capacitive loads, spark suppression capacitors must be provided.

Resistance sensors have been used for many years. The best known are the PT100 and PT1000 sensors. In the temperature range up to 125°C, they are now often replaced by the technically more modern semiconductor sensors, such as the 1-Wire sensors.
