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.

What is Interposing Relay in a PLC System?

Case 1: Interposing Relay system. Suppose we want to operate a motor through a command from the PLC. PLC works on 24 VDC and the motor runs on 230 VAC. We can use a relay in this case. The relay should have a coil voltage rating of 24 VDC and a contact rating of 230 VAC.

Interposing Relays in PLCs | Relay Control Systems

An industrial example of an interposing relay between mismatched devices is shown here, where an AC output proximity switch must trigger an input channel to a Programmable Logic Controller (PLC) rated for only 24 volts DC:

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.

Use of an Interposing Relay for Increased Contactor Speed

The interposing relay''s Normally Open (N.O.) will easily accommodate the higher voltage. At the same time the small coil of the interposing relay is more compatible with the PLC. Experiments suggest that the smaller control relay''s operating opening speed is not as sensitive as the larger contactor.

Interposing Relay | Automation & Control Engineering Forum

An interposing relay cabinet is usually installed in the Motor Control Centre for the purposes of starting/stopping/drive status and ESD of electrical drives. This therefore provides a standard interface to separate the above disciplines. Like Reply. V. Vitor Finkel. Nov 10, 2012

Solution for High-Density Interposing Applications

The 700-HL Terminal Block Relay meets the demand for panel space-savings with our new 6.2 mm wide General Purpose Relay. Interposing relay applications require a significant amount of panel space. For this reason, the 700-HL serves as an interposing relay between the controller and the field devices, allowing flexibility to

Wiring Interposing Relays

Voltage References – Wiring Interposing Relays. When wiring NPN and PNP sensors, we cannot mix them together with the same common input point of the PLC. This is because in an NPN connection the common input point will be at 24VDC. The PNP connection will place the common input point at 0VDC.

High-Density Interposing Applications

6 FAQs about [Interposing relay cabinet Bahamas]

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.

Why is interposing relay important?

This will collapse the relay coil’s magnetic field. Interposing relay saves one system when the system connected on the other side of the relay gets damaged. The damage can be due to a short circuit or earthing issue. Interposing relay will also make communication between high voltage rated PLC and low voltage rated PLC.

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.

What is an example of an interposing relay between mismatched devices?

Can control relays be interposed?

It is worth noting that although control relays can be interposed for safety reasons, this is not synonymous with the category of devices called ' safety relays ' with redundant sets of input coils and contact sets which meet strict safety regulations, normally for motor and motion applications.

What is an interposing relay coil?

Interposing relay coil requires a minimum voltage and lower current than the driving relay. Along with directly performing logic functions, an electromechanical relay can also be used as an interposing system between dissimilar probes, sensors, controllers, and/or control devices.
