The Siemens 7RQ0110-0BM00 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 24 V AC control supply and includes an LED indicator across the coil. Siemens' official 7RQ documentation identifies 7RQ0110-0BM00 as the 24 V AC version in the 2 CO, 10 A, 8-pin relay family.

Siemens 7RQ0110-0BM00 Plug-In Relay

The 7RQ0110-0BM00 belongs to the Siemens SINOVA 7RQ plug-in relay family for industrial control and switching applications. It provides two changeover contact sets in a compact plug-in construction, allowing multiple switching functions to be handled through a single relay.

Siemens' official selection table places this article in the 2CO, 10 A, 8-pin AC relay range.

24 V AC Control Supply

The defining specification of 7RQ0110-0BM00 is its 24 V AC control supply.

Siemens lists the AC versions of this 2CO, 10 A, 8-pin relay 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 connected to the relay coil should match the specified 24 V AC version.

2 Changeover Contacts

The relay provides 2 changeover contacts (2CO).

Each changeover contact has:

• Common contact

• Normally Open (NO) contact

• Normally Closed (NC) contact

This configuration allows the relay to switch two independent circuits or provide multiple auxiliary functions.

Typical applications include:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Signal transfer

• Electrical interlocking

• Alarm circuits

• Machine-control circuits

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

8-Pin Configuration

The 7RQ0110-0BM00 uses an 8-pin plug-in configuration. Siemens specifically identifies the article within the 2CO, 10 A, 8-pin relay family.

The relay should be installed only in a compatible socket with the corresponding mechanical and electrical configuration.

For this relay family, Siemens identifies:

7RQ0211-1BX00 – DIN rail mounting socket

7RQ0212-1BX00 – PCB mounting socket

10 A Contact Rating

The exact relay belongs to the 10 A, 2CO category. Siemens identifies the 7RQ0110 family as a 2 CO, 10 A, 8-pin plug-in relay series.

The permissible switching load should always be checked according to the load type, switching category, operating voltage and complete circuit design.

LED Indicator Across Coil

The 7RQ0110-0BM00 includes an LED indicator across the coil. This provides a visible indication when the relay coil is energized.

The LED indication can help with:

• Panel status checking

• Relay troubleshooting

• Maintenance inspection

• Faster identification of an energized relay

The 7RQ product data lists the LED indicator as a feature of this relay family.

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

• Reduced maintenance time

• Convenient panel servicing

• Simple troubleshooting

• Reusable socket wiring

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

Compatible Mounting Sockets

For the 2CO, 10 A, 8-pin family, Siemens lists:

7RQ0211-1BX00 – DIN rail mounting socket

7RQ0212-1BX00 – PCB mounting socket

This gives flexibility for both DIN rail control panels and PCB-based control assemblies.

Industrial Control Applications

The 7RQ0110-0BM00 can be considered for compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control systems

• Process-control circuits

• Relay interface applications

• Equipment signalling

• Alarm circuits

• Status indication

• Industrial machinery

• Maintenance and replacement applications

The final application depends on the relay contacts, coil circuit and connected load.

Control and Interlocking Applications

The two changeover contacts allow the relay to provide more than one switching function from a single coil.

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

• Electrical interlocking

• Equipment status feedback

• Alarm indication

• Auxiliary control

• Signal switching

• Process-status indication

• Control sequence functions

The exact use of the contacts should follow the applicable electrical design.

Difference from 48 V AC Version

The 7RQ0110-0BN00 is the 48 V AC version, while 7RQ0110-0BM00 is the 24 V AC version.

Both belong to the same 2CO, 10 A, 8-pin relay family, but their coil/control voltages are different.

Difference from 110 V AC and 230 V AC Versions

The same Siemens family includes:

7RQ0110-0BM00 – 24 V AC

7RQ0110-0BN00 – 48 V AC

7RQ0110-0BP00 – 110 V AC

7RQ0110-0BQ00 – 115 V AC

7RQ0110-0BR00 – 230 V AC

The exact control voltage must be selected according to the available supply.

Difference from 24 V DC Version

Siemens also provides a 24 V DC version in the same 2CO, 10 A, 8-pin family:

7RQ0110-0BC00 – 24 V DC

The 7RQ0110-0BM00 is specifically the 24 V AC version.

AC and DC coil versions are separate articles and should not be interchanged without checking the control circuit.

Replacement and Maintenance

The 7RQ0110-0BM00 can be used as a replacement where an existing installation requires a 2CO, 10 A, 8-pin, 24 V AC plug-in relay.

Before ordering, verify:

• Exact relay article number

• Coil/control voltage

• AC or DC requirement

• 2CO contact configuration

• 8-pin arrangement

• Contact rating

• Compatible relay socket

• Existing control circuit

This helps prevent selecting a similar relay with a different coil voltage.
