Product Description

Siemens 7RQ0110-0BN00 Plug-In Relay – 2CO, 8-Pin, 10A, 48V AC

The Siemens 7RQ0110-0BN00 is a SINOVA 7RQ plug-in relay with 2 changeover contacts (2CO), an 8-pin configuration, and a 10 A contact rating. The exact article is designed for a 48 V AC control supply and includes an LED indicator across the coil. Siemens' official 7RQ documentation places this article in the 2CO, 10 A, 8-pin AC relay family.

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

Siemens 7RQ0110-0BN00 Plug-In Relay

The 7RQ0110-0BN00 belongs to the Siemens SINOVA 7RQ plug-in relay range. It provides two changeover contact sets in an 8-pin plug-in format, making it suitable for applications where multiple switching functions are required from a single relay.

The exact article is the 48 V AC version of the 2CO, 10 A, 8-pin relay family.

48 V AC Control Supply

The defining specification of 7RQ0110-0BN00 is its 48 V AC control supply.

Siemens lists the AC versions of the same 2CO, 10 A, 8-pin family as:

• 24 V AC – 7RQ0110-0BM00

• 48 V AC – 7RQ0110-0BN00

• 110 V AC – 7RQ0110-0BP00

• 115 V AC – 7RQ0110-0BQ00

• 230 V AC – 7RQ0110-0BR00

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

2 Changeover Contacts

The relay provides 2 changeover contacts (2CO).

Each changeover contact has a common terminal and can switch between normally open and normally closed paths depending on the relay state.

This configuration can support applications such as:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Alarm signalling

• Electrical interlocking

• Machine-control circuits

• Signal transfer

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

8-Pin Configuration

The 7RQ0110-0BN00 uses an 8-pin plug-in configuration. Siemens specifically groups this article under the 2CO, 10 A, 8-pin relay category.

The relay should be installed only in a compatible socket having the corresponding 8-pin mechanical and electrical arrangement.

10 A Contact Rating

The exact article belongs to the 10 A, 2CO relay family. Siemens' official selection table identifies 7RQ0110-0BN00 under 2 CO, 10 A, 8 pin.

The actual switching load should be evaluated according to the connected load type, switching conditions and the ratings of the complete relay circuit.

LED Indicator Across Coil

The 7RQ0110-0BN00 includes an LED indicator across the coil. This provides visual indication when the relay coil is energized.

This feature can make panel inspection and troubleshooting easier by allowing technicians to quickly identify relay energization.

Plug-In Construction

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

This arrangement supports:

• Easy relay replacement

• Faster maintenance

• Simple panel servicing

• Convenient troubleshooting

• Reusable socket wiring

The socket remains connected to the circuit while the plug-in relay can be removed separately.

Compatible Mounting Sockets

For the 2CO, 10 A, 8-pin 7RQ relay family, Siemens identifies compatible sockets including:

7RQ0212-1BX00 – PCB mounting socket

7RQ0211-1BX00 – DIN rail mounting socket

This allows the same relay family to be used in both PCB-based and DIN rail control-panel arrangements.

Industrial Control Applications

The 7RQ0110-0BN00 can be considered for compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control circuits

• Process-control systems

• Relay interface circuits

• Equipment signalling

• Alarm circuits

• Status indication

• Industrial machinery

• Maintenance and replacement applications

The final application should be selected according to the relay's electrical specifications.

Control and Interlocking Applications

The two changeover contacts allow one relay to control multiple circuit paths.

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

• Electrical interlocking

• Status feedback

• Auxiliary control

• Alarm indication

• Signal switching

• Equipment monitoring

• Control sequence functions

The exact use of each contact should be defined by the electrical circuit.

Difference from 24 V AC Version

The 7RQ0110-0BM00 is the 24 V AC version of the same family, while 7RQ0110-0BN00 is the 48 V AC version. Siemens lists both as separate article numbers.

The relay coil voltage must be matched to the control supply.

Difference from 110 V AC and 230 V AC Versions

Within the same 2CO, 10 A, 8-pin AC family:

7RQ0110-0BN00 – 48 V AC

7RQ0110-0BP00 – 110 V AC

7RQ0110-0BR00 – 230 V AC

Selecting the exact control-supply voltage is essential for correct relay operation.

Difference from DC Relay Versions

Siemens also provides DC versions in the same 2CO, 10 A, 8-pin family, including:

• 24 V DC – 7RQ0110-0BC00

• 48 V DC – 7RQ0110-0BD00

• 110 V DC – 7RQ0110-0BE00

The 7RQ0110-0BN00 is specifically the 48 V AC version and should not be confused with the 48 V DC article.

Replacement and Maintenance

The 7RQ0110-0BN00 can be used as a replacement relay where an existing installation requires a 2CO, 10 A, 8-pin, 48 V AC plug-in relay.

Before ordering, verify:

• Exact relay article

• Control-supply voltage

• AC or DC requirement

• Contact configuration

• Number of pins

• Contact rating

• Compatible socket

• Existing control circuit

This helps prevent replacing a 48 V AC relay with a 48 V DC or different-voltage model.

The Siemens 7RQ0110-0BN00 is relevant for:

• Electrical panel builders

• Industrial buyers

• Electrical contractors

• Machine builders

• Maintenance departments

• 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.
