The relay operates with a 230 V AC control supply and includes an LED indicator across the coil. Siemens' official 7RQ documentation identifies this exact article in the 2 CO, 10 A, 8-pin relay family.

Important SKU formatting note: the supplied SKU 7RQ01100BR00 corresponds to Siemens article number 7RQ0110-0BR00. This is the format used in Siemens' selection and ordering data.

For SB Smart, this product is positioned as a Siemens industrial plug-in relay for control circuits, electrical panels, machine control, signalling, switching and relay-interface applications.

Siemens 7RQ0110-0BR00 Plug-In Relay

The 7RQ0110-0BR00 belongs to the Siemens SINOVA 7RQ plug-in relay family. It is designed for industrial switching and control applications where a compact relay with multiple changeover contacts is required.

The relay uses an 8-pin configuration and provides 2 changeover contacts, allowing two separate switching functions to be controlled from the same relay. Siemens lists the 230 V AC version under the 2CO, 10 A category.

230 V AC Control Supply

The exact 7RQ0110-0BR00 operates with a 230 V AC coil/control supply at 50/60 Hz. Current product information also confirms the 230 V AC specification.

The control voltage should match the relay coil voltage before installation.

2 Changeover Contacts

The relay provides 2 changeover contacts (2CO).

Each changeover contact includes:

• Common contact

• Normally Open (NO) contact

• Normally Closed (NC) contact

This configuration allows the relay to control two independent circuits or provide multiple status and control functions.

Typical applications include:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Electrical interlocking

• Alarm signalling

• Machine-control circuits

10 A Contact Rating

The 7RQ0110-0BR00 belongs to Siemens' 10 A contact-rating category. Siemens' official selection data specifically groups this article under 2 CO, 10 A, 8 pin plug-in relays.

The actual permissible load should be checked against the relay contact characteristics, load type, switching category and system requirements.

8-Pin Configuration

The relay has an 8-pin connection arrangement. This pin configuration is used for the two changeover contacts and the relay coil interface.

The corresponding socket must have the correct 8-pin mechanical and electrical configuration.

Siemens lists compatible mounting sockets for this 2CO, 10 A relay family including:

• 7RQ0212-1BX00 – PCB mounting

• 7RQ0211-1BX00 – DIN rail mounting

LED Indicator Across Coil

The 7RQ0110-0BR00 includes an LED indicator across the coil. This provides a visual indication when the relay coil/control circuit is energized. Siemens specifies the LED indicator as a standard feature for this relay family.

This can make panel inspection and troubleshooting easier by providing a visible indication of relay energization.

Plug-In Construction

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

This provides several practical advantages:

• Easy relay replacement

• Reduced maintenance time

• No direct soldering of the relay

• Simplified panel servicing

• Reusable socket wiring

The fixed socket remains connected while the relay can be removed and replaced.

DIN Rail and PCB Socket Compatibility

The relay itself is a plug-in component and can be used with compatible Siemens sockets selected according to the installation method.

For the 2CO, 10 A family, Siemens specifies:

PCB mounting: 7RQ0212-1BX00

DIN rail mounting: 7RQ0211-1BX00

This allows the same relay family to be integrated into different panel or PCB arrangements.

Electrical Switching Applications

The two changeover contacts allow the relay to be used in circuits requiring additional switching functions.

Depending on the circuit design, the relay can support:

• Motor-control circuits

• Machine-control circuits

• Process-control circuits

• Signal switching

• Alarm circuits

• Status indication

• Auxiliary control

• Electrical interlocking

The actual application depends on the complete control-system design.

Industrial Control Panels

The 7RQ0110-0BR00 is suitable for use in industrial electrical assemblies where a compact plug-in relay is required.

Typical applications include:

• Industrial control panels

• Machine control cabinets

• Electrical switchboards

• Process-control panels

• Relay interface circuits

• Equipment signalling systems

• Industrial machinery

• Maintenance and replacement applications

Mechanical and Electrical Construction

Current product information identifies the relay with:

• AgNi contact material

• IP40 relay protection

• IP20 base protection

• 50–60 Hz frequency

• Double insulation

• 21 × 38.5 × 28 mm dimensions

• Approx. 43 g weight

These characteristics make the relay suitable for compact industrial control applications.

Operating Performance

Current product specifications list an operating time of approximately 16 ms, including bounce time, and a release time of approximately 8 ms, including bounce time. The specified operating temperature range is -40°C to +55°C for AC coil versions.

The actual application environment should remain within the specified operating limits.

Relay Life

Product data lists the mechanical life as approximately:

• 10 million operations for AC coil versions

• 20 million operations for DC coil versions

For the exact 230 V AC article, the AC mechanical-life specification is the relevant value.

Electrical life depends on the actual load and switching conditions.

Contact Material

The relay uses AgNi (silver-nickel) contact material, as listed in current product information.

The appropriate contact application should still be selected according to the load characteristics and relay specifications.

Replacement and Maintenance

The 7RQ0110-0BR00 can be used as a replacement relay in compatible Siemens 7RQ installations requiring a 2CO, 10 A, 230 V AC relay.

Before ordering, verify:

• Relay article number

• Coil voltage

• 2CO contact configuration

• 8-pin arrangement

• Contact rating

• Compatible socket

• Mounting arrangement

• Existing control circuit

This avoids replacing a relay with a similar-looking article having a different coil voltage or contact rating.

Difference from 6 A 2CO Relay

Siemens also offers 6 A, 2CO, 8-pin 7RQ relays. The 10 A article 7RQ0110-0BR00 is distinct from the 6 A family such as 7RQ0100-0BR10. Siemens' official selection table separates these relay families by contact rating and standard features.

This distinction is important when selecting a replacement relay.

Difference from 3CO Relay

The 7RQ0110-0BR00 provides 2CO, while Siemens' 3CO relay family uses an 11-pin configuration. For example, the 230 V AC 3CO article is 7RQ0100-0CR00.

Therefore, the 2CO and 3CO relays require different socket configurations.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 7RQ0110-0BR00 is relevant for:

• Electrical panel builders

• Industrial buyers

• Electrical contractors

• Maintenance departments

• Machine builders

• OEM maintenance teams

• Control-panel assemblers

• Electrical product dealers

• Replacement-part procurement

For SB Smart, the product is positioned around industrial electrical product supply and procurement.

The core relay configuration is supported by Siemens' official 7RQ documentation; mechanical and environmental specifications are supported by current product data.
