The SO-52v11-eMC-A controller is designed to control the cooling system of oil transformers and two-winding and three-winding autotransformers. The main task of the controller is to maintain the temperature of the solid insulation within the assumed limits and to prevent its overheating. The controller also monitors the oil insulation. Maintaining the proper temperature should be independent of the changing load, ambient temperature and other environmental conditions. The controller also controls the switching on of the cooling system elements by rotating switching the order of switching on the cooling groups. The controller also has an automatic cooling function to prevent the so-called "Found devices".
The basic parameters of the device are: maximum oil temperature measurement and load current measurement; external binary signals are also collected, e.g. signaling that the transformer is energized. The temperature of the winding's hottest point is also calculated. The method of its calculation is selected during the driver configuration. The device has a sufficient number of binary inputs and outputs required for control and signaling to the SSiN station supervisory system. The cooling controller also has analog outputs, which are intended for the analog presentation of the measured temperatures.
The controller performs its functions by handling feedback signals and generating warnings along with sound, light and other alarms. They result from previously defined logical dependencies or occurring sequences of events.
The controller has a modular structure and its basic components are:
The SO-52v11-eMB controller is a device designed to monitor the transformer cooling system. It is equipped with a set of digital and analog inputs that can perform all the required functions. The device also measures temperature.
The SO-52v11-eMB controller consists of the following modules:
The SO-52v11-eMB controller is designed to work with the SYNDIS ES and ESB software. 
The telecontrol system based on SO-52v11-eMT devices is used to monitor and control geographically dispersed processes of technological interlocks between remote primary devices such as circuit breakers, disconnectors, earthing switches operating at the ends of a power line. The system also collects states at distant substations. Such a system integrates dispersed primary devices into one coherent telemechanics system. Binary states read at the inputs of one of the devices are transferred using a special, reliable PRP protocol, via optical fiber links, to the outputs of the other device. Analogous, binary states sent to the second device are transferred to the outputs of the first device. The telecontrol system can be used as part of the security system.
The device has a modular structure with IP50 resistance class. A 19 ”wide cassette can accommodate the following configuration:
The SMT-102/103 is a Transformer Overvoltage Transmitter Registration Module. The module description is in the device group "Devices> Disturbance recorders".
The CPT-00x measuring probe is intended for use in on-line monitoring systems of transformer bushings. The probe, together with the capacitance of the bushing, forms a capacitive divider that matches the voltage level from the bushing to the input of the SMT-10x recording device. It works with the SMT-10x module for recording overvoltages of the transformer bushing. 
The specialized USP-001-PZ transducer is designed to supervise the operation of the on-load tap changer. The device monitors its condition and signals anomalies occurring in the operation of the switch. Additionally, the module records predefined data, which are used during the analysis of the correct operation of the switch. These parameters can be read from the device remotely or locally and processed e.g. by external software. The device can be a component of any distributed telemechanics system in the environment of both the energy sector and any industrial installations. The device can work with the SYNDIS system, and equally well with any other SCADA type system.
The USP-001-PZ device is equipped with the following types of input and output connectors:
