Industrial relays
Industrial Relays and Bases
Devices intended for construction of automation and signalling boards. They are mainly used for command
transfer towards the executive mechanisms. Currents of comparatively heavy values enabling the direct control
of industrial executive mechanisms are commuted in comparatively small sizes. The contact surfaces are made
from silver-coated electrolytic copper. The entire contact system is closed within a lid of colourless fire-proof
plastic with a test-button installed to it. The base provides a safe electric connection of the conductors of the
electric installation and the relays and is used to install the relay to the DIN busbar.

Industrial Solid State Relays (SSR)
Industrial SSR are intended for mounting in power and control cabinets as an output switch devices with reliable ON/
OFF performance. The SSR are based on the CMOS technology. The non-contact electronic switch is optically separated
from the input signal by a photoelectric coupler. This allows use of switch currents of up to 50A despite of the devices
small overall size. Another important feature of the relay is that output load can be regulated depending on the input
signal value. The relay is mainly used to transmit control signals to actuating mechanisms since it can work at comparatively high currents making it possible to directly control actuators. SSR have transparent plastic covers to additionally
improve their safety level. The SSR use is connected with considerable heat emissions, so measures must be taken to
dispense the excessive thermal energy in the atmosphere. This is achieved through application of specially deigned
radiators. The correct definition of radiator parameters is of critical importance. It is made by calculating the heat generation capacity with the formula: Heat generation = active load current x 3.0 W/A. The heat removal surface is estimated
with the help of the following graphic:
