Product Description

Siemens 7RQ0100-0DR00 Plug-In Relay – 4CO, 14-Pin, 5A, 230V AC

The Siemens 7RQ0100-0DR00 is a SINOVA 7RQ plug-in relay with 4 changeover contacts (4CO), a 5 A contact rating, and a 230 V AC control supply. Siemens' official 7RQ documentation identifies this article as the 4CO, 5 A relay with a 14-pin configuration and an LED indicator across the coil.

Important product-title correction: The supplied title says 25 pin, but the Siemens documentation and current product data identify 7RQ0100-0DR00 as a 14-pin relay, not 25-pin. For the SB Smart product page, the title should therefore use 14-pin to avoid incorrect product information.

Siemens 7RQ0100-0DR00 Plug-In Relay

The 7RQ0100-0DR00 belongs to the Siemens SINOVA 7RQ plug-in relay family and is designed for industrial control, switching, signalling and auxiliary circuit applications.

The relay provides four changeover contacts, allowing multiple independent switching functions to be handled through one compact relay. Siemens' official product documentation places the article in the 4CO, 5 A relay family.

230 V AC Control Supply

The exact 7RQ0100-0DR00 is designed for a 230 V AC control supply.

Siemens lists the AC control-voltage variants in the same 4CO, 5 A family, including:

• 24 V AC – 7RQ0100-0DM00

• 48 V AC – 7RQ0100-0DN00

• 110 V AC – 7RQ0100-0DP00

• 115 V AC – 7RQ0100-0DQ00

• 230 V AC – 7RQ0100-0DR00

The control voltage should be matched to the exact relay article before installation.

4 Changeover Contacts

The relay provides 4 changeover contacts (4CO).

Each changeover contact provides a common connection that switches between normally open and normally closed paths according to the relay state.

Four changeover contacts can support several independent switching functions from one relay, including:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Signal transfer

• Electrical interlocking

• Alarm circuits

• Machine-control functions

The connected load should remain within the applicable relay contact ratings.

14-Pin Configuration

The correct Siemens configuration for 7RQ0100-0DR00 is 14 pins. Siemens' official 7RQ documentation and current Indian product information identify the article as a 14-pin, 4CO, 5 A relay.

This is important when selecting the matching relay socket. A socket with an incorrect pin configuration should not be used.

5 A Contact Rating

The 7RQ0100-0DR00 belongs to the 4CO, 5 A relay category.

The actual switching capability should be selected according to the load type, voltage, switching frequency and applicable relay-contact specifications rather than relying only on the nominal current rating.

LED Indicator Across Coil

The relay includes an LED indicator across the coil, providing a visible indication when the relay is energized. Current product listings also identify the LED indicator as a key feature of this exact article.

This can assist with:

• Panel status checking

• Relay troubleshooting

• Maintenance inspection

• Identifying an energized relay

Plug-In Construction

The 7RQ0100-0DR00 uses a plug-in relay design, allowing it to be installed into a compatible socket.

This construction makes relay replacement more convenient because the socket can remain connected to the control-panel wiring while the relay itself can be removed.

Advantages include:

• Easy replacement

• Reduced maintenance time

• Convenient troubleshooting

• Reusable socket wiring

• Simplified panel servicing

Compatible Relay Sockets

For the 4CO, 5 A 7RQ relay family, Siemens identifies compatible socket arrangements including:

7RQ0201-1DX00 – DIN rail mounting socket

7RQ0202-1DX00 – PCB mounting socket

The socket should be selected according to the required mounting method and the exact relay configuration.

Industrial Control Applications

The 7RQ0100-0DR00 can be considered for compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control systems

• Process-control circuits

• Relay interface systems

• Equipment signalling

• Alarm circuits

• Status indication

• Auxiliary switching

• Industrial machinery

• Maintenance and replacement applications

Multiple Switching Functions

The 4CO configuration allows one relay to provide multiple switching paths.

Depending on the control-system design, the four contacts can be used for:

• Multiple status signals

• Interlocking functions

• Alarm circuits

• Auxiliary control

• Signal switching

• Equipment monitoring

• Control-sequence functions

The actual use of each contact should follow the complete electrical design and load requirements.

Difference from 2CO Relay

The 7RQ0110 family is used for 2CO relays, while 7RQ0100-0DR00 provides 4CO contacts.

The 4CO relay therefore provides additional independent changeover contacts from one relay, while using a different socket configuration.

Difference from 3CO Relay

The Siemens 3CO relay family uses an 11-pin configuration, whereas 7RQ0100-0DR00 is a 4CO, 14-pin relay.

For example, Siemens identifies 7RQ0100-0CR00 as the 3CO, 10 A, 11-pin 230 V AC version.

This makes the 3CO and 4CO relay/sockets different product configurations.

Difference from 4CO, 7A Socket System

The 7RQ0100-0DR00 is the relay itself, rated at 4CO, 5 A.

The 7RQ0201-1DX00 and 7RQ0202-1DX00 are the corresponding 4CO, 7 A socket category articles listed by Siemens for the mounting system.

Therefore, the relay and socket ratings should always be checked together before replacement or assembly.

Replacement and Maintenance

The 7RQ0100-0DR00 can be used as a replacement where an existing installation requires a 4CO, 14-pin, 5 A, 230 V AC plug-in relay.

Before ordering, verify:

• Exact relay article

• Control-supply voltage

• 4CO contact configuration

• 14-pin arrangement

• Contact rating

• Compatible socket

• Existing control circuit

This is particularly important because current online listings have inconsistent pin descriptions for this article. Siemens' official documentation should be treated as the primary reference, which identifies the article as 14-pin.
