Technical specifications

Product type: electromagnetic intermediate relay
Manufacturer: LANBOO
Mounting: DIN rail
Construction: ultra slim, subminiature
Control voltage (coil): 12V
Contact type: 1NO + 1NC (1 changeover contact – SPDT / 1CO)
Rated current: 6A (250VAC)
Contact resistance: ≤50 mΩ
Contact load: low power
Indication: LED (operation status)
Protection: sealed construction
Mounting hole diameter: ~6 mm
Application: general purpose

Functions

Signal switching (1NO/1NC) – universal control
LED indication – clearly visible relay status
Ultra slim design – saves space in electrical panels
Sealed construction – protection against dust and environmental impact
Fast and reliable operation – suitable for automation
DIN mounting – easy integration into panels

Usage

For household users: In lighting control systems, control of fans, pumps or alarm systems, Smart home solutions (via PLC or controllers)
For engineers / automation specialists: PLC signal expansion and isolation, control of automated lines, control of sensors and actuators, design of compact panels
For electricians: Assembly of electrical panels, implementation of signal circuits, quick and convenient installation in limited space, service work – clear LED indication

Practical applications

Lighting control via PLC or push button: PLC sends a 12V signal to the relay – the relay switches the 230V circuit – the luminaire turns on
Fan or pump control: A sensor (e.g., temperature) sends a signal – the relay turns on the fan – the system operates automatically
Control of signal lamp or siren: Controller sends a signal to the relay – the relay activates the signal lamp or siren – the operator sees or hears the warning
Control of multiple circuits with one signal: The relay switches contacts (NO/NC) – one signal controls multiple functions

Advantages

Very compact (ultra slim design)
LED indication – convenient for diagnostics
Sealed construction – durability
Universal 1NO/1NC contact
Easy mounting on DIN rail

Disadvantages

Limited load (up to 6A – not suitable for high-power circuits)
Often requires an additional socket (depending on model)

What does 1NO/1NC mean?
It means that the relay has one normally open and one normally closed contact (changeover contact).

Is this relay suitable for PLC control?
Yes, it is perfectly suitable as an intermediate relay between PLC and load.

Can it be used to control 230V devices?
Yes, if the load does not exceed 6A (250VAC).

Why is LED indication needed?
It allows you to see whether the relay is energized – very convenient for diagnostics.
