Interface Relays
Interface relays are designed to guarantee the interfacing digital
control signals that are being exchanged between the processing units and other crucial
automation control components are maintained. Interface relays are used with components that
are isolated from each other and cannot be allowed to be directly connected due
to differences in their voltage.
Interface
relay modules are provided with galvanic isolation between the final and receiving
control systems of the interface relay which protects the signals from
interference. An interface relay guarantees electrical and information
compatibility and supplies the required algorithms for the interaction of special
control instruments components.
General-purpose relays have some level of isolation between
output and input circuits, but this function is only secondary and isn’t decisive.
However, the property of galvanic isolation in interface relays is decisive. Interface
relays are typical utilised in control and protection systems such as powerful
radio-electronic, electro physical, X-ray and many more high-power (10-100kV) applications.
Kempston Controls,a leading supplier of electrical and electronic components, stocks an extensive range of interface
relays from all the leading brands including Weidmuller,
ABB,
Finder,
MURR
and many more.
