The hopf FO-StarCoupler 4811 for 35 mm DIN rail mounting (DIN EN 50 022) is a low-cost solution for the active distribution of a FO signal to up to 7 FO outputs. All FO-StarCoupler FO components are ST (bayonet) type and designed for multimode cables. Each component of the FO-StarCoupler has its own status LED. The equipment is very widely used to transmit time server signals to several devices at far distances by a master time server device and optical fiber cables; finally, converting them into electrical signals next to each device.

The system 6855 is a DCF77-based time server system. This means that the system is synchronized to local time (standard time with ST/WT conversion, if needed). The 6855 Time Server System is available in a 3U version as well as a 1U Slim Line version. Both offer extensive modularity that allows customized solutions to be realized with the 6855 DCF77 system. The system can be developed using functional boards, added by the customer. So, its performance can be easily upgraded on the site at low cost. Performance panels can also be replaced directly on site.

DCF77 4417 / 4418 / 4420 / 4436 / 4437 antennas are all German hopf antennas with active directional capability and an electrical design. Ferrite antennas are used for long wave range frequencies to keep the antennas small. The oscillating circuit in the antenna, which is made of a wire ferrite rod and various capacitors, is set up on 77.5 kHz. DCF77 is a standard for transmitting time (hours, minutes and seconds) and date to clocks and timing devices, and it is transmitted to devices with high accuracy by radio (local transmitter).

Switch-Box - System 5000 was designed and developed to operate redundant clock systems in "hot standby function with automatic status-dependent signal switchover" mode of operation. The system 5000 is used when the most urgent demands are presented on the availability of a master clock system. The German Hopf system 5000 ensures that the output signal is given to the customer program with little error through the clock system. This system detects the error-dependent signal change between the primary system and its redundant system by monitoring the state of the respective clock system

The HOP5750-30TX switch has 24 ports with 2.5G of capacity, and 6 ports with 10G of capacity. This switch is made by HOUPER Company. It is one of the HOP5750 series switches that are sold in the network equipment market. This model of switch allows you to connect up to 2.5 gigabytes per port. As a Layer 3 switch, it has extremely high switching capacity, and supports multi-port reflective analysis and service flow-based image analysis. It also supports the mechanism of security filters such as ACL.

EVD4 is an evolved PID controller complete with driver for stepper motors specially designed for the management of electronic expansion valves in refrigerant circuits. It features sophisticated control functions 

and can be used in many operating configurations in refrigeration and air-conditioning systems, such as:

- PID control of superheat with protection and safety compensation functions;

- PID control on one measurement (pressure or temperature);

- positioner for electronic expansion valves controlled by 4 to 20 mA or 0 to 10 Volt signal. 

The device is configured and the address set via serial interface and the user interface software is stored in non-volatile memory.

This electric current is measured by a current transformer: by varying the level of water using a fill solenoid valve and due to the evaporation process, the current, and consequently steam production, can be modulated. Due to evaporation, the level of water decreases and must therefore be topped up. As the steam produced does not carry mineral salts, the salt concentration in the water and therefore the conductivity increases, and has to be periodically diluted by draining part of it using the drain pump and replacing it with new water.

The CAREL DPW* series serial probes are devices used for applications in the air-conditioning, refrigeration, heating and air handling sectors. These are installed in combination with the controllers that feature the serial connection. As well as the wall-mounted room probes, industrial and duct versions are also available.
