Interface Relays
What are Interface
Relays?
An interface
relay module is 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.
Where are
Interface Relays used?
A general-purpose
relay module has 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, electrophysical, X-ray and other high-power (10-100kV)
applications.
Kempston
Controls, a leading supplier of automation and control components, stocks an
extensive range of plc interface relays from all the leading brands
including Weidmuller, ABB, Finder, MURR and many
more.

dedicated sales team a call on +44 (0) 1933 411411 or use the contact form
