Siemens 7RQ0110-0BC00 Plug-In Relay

The 7RQ0110-0BC00 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 controlled through one relay.

The exact article is the 24 V DC version of the Siemens 2CO, 10 A, 8-pin relay family.

24 V DC Control Supply

The defining specification of 7RQ0110-0BC00 is its 24 V DC control supply.

Within the same Siemens 2CO, 10 A, 8-pin DC relay family, the control-voltage variants include:

• 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 connected to the specified 24 V DC control supply.

2 Changeover Contacts

The relay provides 2 changeover contacts (2CO).

Each changeover contact has:

• Common contact

• Normally Open (NO) contact

• Normally Closed (NC) contact

The two changeover contacts can be used for different control, indication or switching functions within the same electrical circuit.

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 contact ratings of the relay.

8-Pin Configuration

The 7RQ0110-0BC00 uses an 8-pin plug-in configuration.

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

Compatible socket options for this relay family include:

7RQ0211-1BX00 – DIN rail mounting

7RQ0212-1BX00 – PCB mounting

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

10 A Contact Rating

The exact relay belongs to the 2CO, 10 A category.

The 10 A rating should be considered together with the contact material, connected load, switching category, operating voltage and circuit conditions. The complete relay application should remain within the applicable Siemens specifications.

LED Indicator Across Coil

The 7RQ0110-0BC00 includes an LED indicator across the coil. This provides a visual indication when the relay coil is energized.

The LED indication can assist with:

• Panel status checking

• Relay troubleshooting

• Maintenance inspection

• Quick identification of an energized relay

Plug-In Construction

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

This provides several maintenance advantages:

• Easy relay replacement

• Faster servicing

• Convenient troubleshooting

• Reusable socket wiring

• Reduced wiring disturbance during replacement

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

Compatible Mounting Sockets

For the 2CO, 10 A, 8-pin 7RQ relay family, Siemens provides:

7RQ0211-1BX00 – DIN rail mounting socket

7RQ0212-1BX00 – PCB mounting socket

The correct socket should be selected according to the required installation method.

Industrial Control Applications

The 7RQ0110-0BC00 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

The final application depends on the complete 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, these contacts can be used for:

• Electrical interlocking

• Equipment status feedback

• Alarm indication

• Auxiliary control

• Signal switching

• Process-status indication

• Control sequence functions

The exact contact utilization should follow the relay and load specifications.

Difference from 48 V DC Version

The 7RQ0110-0BD00 is the 48 V DC version, while 7RQ0110-0BC00 is the 24 V DC version.

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

Difference from 24 V AC Version

The 7RQ0110-0BM00 is the 24 V AC version, while 7RQ0110-0BC00 is specifically the 24 V DC version.

Therefore:

7RQ0110-0BC00 = 24 V DC

7RQ0110-0BM00 = 24 V AC

The control supply must match the exact relay article.

Difference from 110 V DC Version

The 7RQ0110-0BE00 is the 110 V DC version, while 7RQ0110-0BC00 is the 24 V DC version.

The two articles have the same 2CO, 10 A and 8-pin arrangement, but different coil voltages.

Replacement and Maintenance

The 7RQ0110-0BC00 can be used as a replacement where an existing installation requires a 2CO, 10 A, 8-pin, 24 V DC plug-in relay.

Before ordering, verify:

• Exact relay article

• Control-supply voltage

• DC operation

• 2CO contact configuration

• 8-pin arrangement

• Contact rating

• Compatible socket

• Existing control circuit

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