São Tomé and Príncipe interposing relay cabinet

Here in this case we are operating a PLC with a contactor with a single-phase AC supply. 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. . The PLC relay can only avail 1A at 110 VAC, but the relay connected to the controller needs 3A at 110 VAC. Here, an interposing relay with. . The function of interposing relay is to separate 1. Two dissimilar or non-identical systems. 2. One voltage level from another. 3. Energize the starter to switch on the electric motor. [pdf]

FAQS about São Tomé and Príncipe interposing relay cabinet

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.

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.

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.

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).

What is a relay used to interpose between mismatched devices?

A very simple example of a relay used to interpose between mismatched devices is shown in the following circuit diagram, where a delicate toggle switch is used to control a bank of high-power lights for an off-road vehicle: In this circuit, the relay performs no logic function whatsoever.
