Use of an Interposing Relay for Increased Contactor Speed
What is an interposing relay? The interposing relay – typically a common control relay – is often used in industrial applications. The relay is "interposed" between two systems. It is used for a variety of reasons including: to increase the current handling capabilities of a device such as a Programmable Logic Controller (PLC). to change voltages such as when
Interposing Relay
As the relay coil temporarily outputs a "reverse" voltage, the diode gives that coil a continuous path for its current while dropping a low voltage (about 0.7 volts DC), dissipating the coil''s stored energy in the form of heat at the diode. Interposing relays are also used to connected mismatched PLC outputs and control devices.

Interposing Relays: What Are They?
How Interposing Relays Work. Interposing relays operate by receiving a low-power signal from a control device, such as a PLC, and using it to control the switching of a higher-powered load. When the low-power signal is applied, the interposing relay''s contacts are energized, closing the circuit and allowing current to flow to the load.
