Product Description

Siemens 7RQ0110-0BE00 Plug-In Relay – 2CO, 8-Pin, 10A, 110V DC

The Siemens 7RQ0110-0BE00 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 110 V DC control supply and includes an LED indicator across the coil. Siemens' official 7RQ documentation identifies 7RQ0110-0BE00 within the 2 CO, 10 A, 8-pin DC relay family.

Siemens 7RQ0110-0BE00 Plug-In Relay

The 7RQ0110-0BE00 belongs to Siemens' SINOVA 7RQ plug-in relay family, developed for industrial control, switching, signalling and auxiliary circuit applications.

It provides two changeover contacts in an 8-pin plug-in format, allowing one relay to perform multiple switching functions within a control circuit.

Siemens' official selection data lists the article under the 2CO, 10 A, 8-pin, DC relay category.

110 V DC Control Supply

The defining specification of 7RQ0110-0BE00 is its 110 V DC control supply.

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

• 6 V DC – 7RQ0110-0BA00

• 12 V DC – 7RQ0110-0BB00

• 24 V DC – 7RQ0110-0BC00

• 48 V DC – 7RQ0110-0BD00

• 110 V DC – 7RQ0110-0BE00

The relay coil should be supplied only with the specified 110 V DC control voltage.

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 separate circuits or provide multiple auxiliary functions from a single control signal.

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 relay's applicable contact ratings.

8-Pin Configuration

The 7RQ0110-0BE00 uses an 8-pin plug-in connection.

The relay should be installed into a compatible Siemens socket designed for the corresponding 2CO, 10 A, 8-pin configuration.

Siemens identifies the following compatible socket options for this relay family:

7RQ0211-1BX00 – DIN rail mounting

7RQ0212-1BX00 – PCB mounting

10 A Contact Rating

The exact article belongs to the 2CO, 10 A relay category. Siemens' official selection data identifies 7RQ0110-0BE00 as the 110 V DC article within this family.

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

LED Indicator Across Coil

The 7RQ0110-0BE00 includes an LED indicator across the coil. This provides a visual indication when the relay coil is energized.

The LED can assist with:

• Panel status checking

• Relay troubleshooting

• Maintenance inspection

• Quick identification of an energized relay

Siemens lists the LED indicator as a standard feature of this 7RQ relay family.

Plug-In Construction

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

This design supports:

• Easy relay replacement

• Faster maintenance

• Convenient panel servicing

• Simplified troubleshooting

• Reusable socket wiring

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

Compatible Mounting Sockets

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

7RQ0211-1BX00 – DIN rail mounting socket

7RQ0212-1BX00 – PCB mounting socket

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

Industrial Control Applications

The 7RQ0110-0BE00 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

• Maintenance and replacement applications

The exact application depends on the control circuit and connected load.

Control and Interlocking Applications

The two changeover contacts allow a single relay to control multiple electrical paths.

Depending on the circuit 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 electrical design should consider the relay's contact ratings and load characteristics.

Difference from 110 V AC Version

The 7RQ0110-0BP00 is the 110 V AC version of the same 2CO, 10 A, 8-pin relay family.

The exact article here is:

7RQ0110-0BE00 – 110 V DC

while:

7RQ0110-0BP00 – 110 V AC

The required coil type must match the available control supply.

Difference from 48 V DC Version

The 7RQ0110-0BD00 is the 48 V DC version, while 7RQ0110-0BE00 is the 110 V DC version.

Both have the same 2CO, 10 A, 8-pin configuration, but their coil voltages are different.

Difference from 24 V DC Version

The 7RQ0110-0BC00 is the 24 V DC version of the same relay family.

Therefore:

7RQ0110-0BC00 = 24 V DC

7RQ0110-0BD00 = 48 V DC

7RQ0110-0BE00 = 110 V DC

The control voltage must be selected according to the application.

Difference from 110 V AC and DC Relay

The 7RQ0110-0BE00 is specifically designed for 110 V DC. It should not be substituted with the 7RQ0110-0BP00, which is the 110 V AC variant, simply because both have the same nominal voltage.

The coil type is different and the control supply must match the correct relay article.

Replacement and Maintenance

The 7RQ0110-0BE00 can be used as a replacement where an existing installation requires a 2CO, 10 A, 8-pin, 110 V DC plug-in relay.

Before ordering, verify:

• Exact relay article

• Coil/control voltage

• DC operation

• 2CO contact configuration

• 8-pin arrangement

• Contact rating

• Compatible relay socket

• Existing control circuit

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