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.
Wiring Interposing Relays
The interposing relay will fail and the PLC outputs will be protected. A typical example of an interposing relay would be for a motor starter circuit. You will notice that the motor starter coil uses a 120VAC coil. This will then turn on the 3 phase motor contacts for the motor. Voltage Differences – Wiring Interposing Relays

Why IRP Used for Interface Between DCS and MCC
IRP houses Interposing Relays. The reason for using interposing relays are: 1) To electrically isolate two systems with different voltage levels (e.g., DCS @ 24V, MCC @ 220Vdc, or 230Vac 0r 110Vdc). If there is any short circuit or any electrical disturbance at MCC side, Interposing Relays shall protect DCS from them and vice versa.

Interposing relays | PLCS
Interposing relays were seen as a luxury as they took up too much space, extra wiring, and added cost. Nowadays, PLC''s/PAC''s, cards/modules and relays have become smaller, reducing their footprint in an installation and lessons have been learned on the hazards of not protecting or isolating outputs (or inputs for that matter).

6 FAQs about [Interposing relay cabinet Serbia]
What is an interposing Relay Cabinet?
An interposing relay cabinet is a device used along with automation devices to control heavy load circuits like AC and refrigerators. It has auto/manual switches to bypass the loads from automation controls and provides feedback of switch positions to the control panels.
What is an interposing relay?
Interposing relays can ‘change’ a control (coil) voltage circuit into a higher or lower load voltage. Interposing relays can use a small control (coil) current and translate it into a substantially higher load current that would damage the sensitive digital controls.
What are interposing relay panels in industrial control?
Interposing relay panels in industrial control are used to communicate the signals and status between the Automation system such as DCS & PLC and electrical modules in Machine control centre (MCC) such as motor control units, motors, pumps, lamps, and so on.
Do interposing relays need to be rated?
The coil of the interposing relay should require less voltage and current than the driving relay is rated for, and the contacts of the interposing relay must be rated to handle the requirements of the load ( Controller).
Which type of interposing relay is needed for a PLC?
The PLC relay is DC type with an output voltage of 24 V. But we need a DC type interposing relay with a coil voltage of 24V DC but the contact AC type with 230 V. The PLC operates interposing relay in the first stage & Contactor through its Auxiliary contacts.
