Product Description

Siemens 7RQ0100-0DP00 Plug-In Relay – 4CO, 14-Pin, 5A, 110V AC

The Siemens 7RQ0100-0DP00 is a SINOVA 7RQ plug-in relay with 4 changeover contacts (4CO), a 14-pin configuration, and a 5 A contact rating. The exact article is designed for a 110 V AC control supply and includes an LED indicator across the coil. Siemens' official 7RQ documentation identifies this article within the 4 CO, 5 A, 14-pin relay family.

Important product-title correction: The supplied title says 23 pin, but Siemens documentation identifies 7RQ0100-0DP00 as a 14-pin relay, not 23-pin. The correct product title for SB Smart should therefore use 14-pin. Current product listings also identify this exact article as 4CO, 110 V AC, 5 A, 14-pin.

Siemens 7RQ0100-0DP00 Plug-In Relay

The 7RQ0100-0DP00 belongs to the Siemens SINOVA 7RQ plug-in relay family for industrial control, switching, signalling and auxiliary circuit applications.

It provides four changeover contacts in one compact plug-in relay, allowing several independent switching functions to be controlled from a single relay.

Siemens' official selection and ordering data places the article in the 4CO, 5 A, 14-pin relay group.

110 V AC Control Supply

The exact 7RQ0100-0DP00 is designed for a 110 V AC control supply.

Siemens lists the corresponding AC variants in the same 4CO, 5 A, 14-pin family:

• 24 V AC – 7RQ0100-0DM00

• 48 V AC – 7RQ0100-0DN00

• 110 V AC – 7RQ0100-0DP00

• 115 V AC – 7RQ0100-0DQ00

• 230 V AC – 7RQ0100-0DR00

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

4 Changeover Contacts

The relay provides 4 changeover contacts (4CO).

Each changeover contact has a common terminal and switches between normally open and normally closed paths according to the relay state.

Four changeover contacts can be used for multiple control functions from one relay, including:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Signal transfer

• Electrical interlocking

• Alarm circuits

• Machine-control circuits

The connected load should remain within the applicable contact ratings.

14-Pin Configuration

The correct Siemens configuration for 7RQ0100-0DP00 is 14 pins. Siemens' official documentation specifies the 4CO, 5 A relay family as 14-pin, and current product listings identify the exact 110 V AC article the same way.

This pin configuration must match the compatible relay socket.

5 A Contact Rating

The 7RQ0100-0DP00 belongs to the 4CO, 5 A relay category. Siemens' official selection table identifies the complete 4CO relay family with a 5 A rating.

The actual switching capacity should be evaluated according to the connected load, switching category, operating voltage and complete circuit conditions.

LED Indicator Across Coil

The relay includes an LED indicator across the coil. Siemens lists the LED indicator as a standard feature of the 4CO, 5 A, 14-pin relay family.

This provides a convenient visual indication of relay energization and can assist with:

• Panel inspection

• Maintenance

• Troubleshooting

• Relay-status identification

Plug-In Construction

The 7RQ0100-0DP00 uses a plug-in construction, allowing it to be installed into a compatible relay socket.

This arrangement can simplify:

• Relay replacement

• Preventive maintenance

• Panel servicing

• Troubleshooting

• Spare-part replacement

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

Compatible Relay Sockets

Siemens lists the following mounting sockets for the 4CO relay family:

7RQ0201-1DX00 – DIN rail mounting socket

7RQ0202-1DX00 – PCB mounting socket

The exact socket and relay combination should be checked for mechanical and electrical compatibility before installation.

Industrial Control Applications

The 7RQ0100-0DP00 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

Multiple Switching Functions

The 4CO configuration allows one relay to provide four independent changeover switching functions.

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

• Multiple status signals

• Electrical interlocking

• Alarm circuits

• Auxiliary control

• Signal switching

• Equipment monitoring

• Control-sequence functions

The exact application should follow the relay's electrical ratings and the system design.

Difference from 48 V AC Version

The 7RQ0100-0DN00 is the 48 V AC version, while 7RQ0100-0DP00 is the 110 V AC version.

Both belong to the same 4CO, 5 A, 14-pin family, but their coil voltages differ.

Difference from 24 V AC Version

The 7RQ0100-0DM00 is the 24 V AC version, while 7RQ0100-0DP00 is the 110 V AC version.

The exact control voltage must therefore be matched to the available supply.

Difference from 110 V DC Version

Siemens lists 7RQ0100-0DE00 as the 110 V DC version in the corresponding 4CO, 5 A family. The article 7RQ0100-0DP00 is specifically the 110 V AC version.

110 V AC and 110 V DC versions should not be treated as interchangeable.

Difference from 230 V AC Version

The 7RQ0100-0DR00 is the 230 V AC version, while 7RQ0100-0DP00 is the 110 V AC version. Both are 4CO, 5 A, 14-pin relays.

Replacement and Maintenance

The 7RQ0100-0DP00 can be used as a replacement where an installation requires a 4CO, 14-pin, 5 A, 110 V AC plug-in relay.

Before ordering, verify:

• Exact relay article

• Control-supply voltage

• AC or DC operation

• 4CO contact configuration

• 14-pin arrangement

• Contact rating

• Compatible socket

• Existing control circuit

This is particularly important because the 7RQ family contains several similar-looking voltage variants.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 7RQ0100-0DP00 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.
