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

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

What is Interposing Relay in a PLC System?

Hence, the relay is called Interposing Relay. The commutating diode used in the circuit is used to protect the sensor. Without this diode in the circuit, the coil''s kickback voltage (hundreds of volts in some cases) will definitely destroy the proximity switch. Here the commutating diode is connected in backward with respect to the polarity

Interposing relay Panel | Automation & Control Engineering Forum

Dear Summit, Normally the DO of DCS/PLC are operated by Open collector output of Transistor or TRIAC i.e. TTL logic based on microprocessor. Thus it is not recommended to make relay continuously energised for the long time.To achieve this, a logic is prepared such that a Relay coil (24V) is being energised for moment (2 Sec) in control panel

3 FAQs about [Dominica 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 is an example of an interposing relay between mismatched devices?

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:

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).
