METZ CONNECT KRA-S-M6/21 Módulo de relé de acoplamiento 24V AC/DC 1 conmutador 8A blanco 11061213

In industrial control cabinets, the METZ CONNECT KRA-S-M6/21 coupling relay module reliably switches loads up to 8 A. Its 24 V AC/DC coil and one changeover contact make it a direct fit for automation systems using standard DIN rail mounting.

Key specifications

• Coil voltage: 24 V AC/DC
• Contact configuration: 1 changeover (SPDT)
• Max switching current: 8 A
• Max switching voltage: 250 V AC
• Mounting: DIN rail TS35
• Dimensions (W x H x D): 11.2 x 87.5 x 60 mm
• Operating temperature: -20 to 55 °C

Why choose it

The slim 11.2 mm housing saves space on the DIN rail, while screw terminals ensure secure wiring. The white polyamide body is durable and easy to identify in crowded panels.

Ideal use cases

• Galvanic isolation between control and load circuits
• Switching of small motors, valves, or lamps in building automation
• Signal multiplication in PLC outputs

Good to know

The module is designed for AC or DC coil supply at 24 V, making it versatile for mixed-voltage control systems. It operates reliably in ambient temperatures from -20 to 55 °C.
