Product information

Description

The Siemens 3RQ4118-1AF00 is a high-performance plug-in coupling relay engineered for industrial automation and control applications. This compact device serves as a reliable interface between control systems and field devices, ensuring efficient signal switching and electrical isolation. With its slim design and robust construction, it is specifically built to optimize space within control cabinets while maintaining high operational standards.

Advantages

The primary benefit of this coupling relay is its extremely compact 6.2mm width, which allows for high-density mounting in limited spaces. The device supports both AC and DC voltage at 230V, providing flexibility in various electrical environments. Its screw terminal connection ensures a secure and vibration-resistant installation, while the single changeover contact offers versatile switching capabilities for diverse control tasks.

Suitable for

  • Industrial automation control panels
  • Signal isolation between PLC and field devices
  • Switching small to medium-sized loads
  • Space-constrained electrical cabinets

When it may not be suitable

This relay is not intended for switching high-power loads exceeding its 6A thermal current rating. It is also not suitable for environments requiring specialized protection against extreme moisture or corrosive gases without additional housing.

Key specifications

  • Operating voltage: 230V AC/DC
  • Contact configuration: 1 change-over (1CO) contact
  • Thermal current: 6A
  • Width: 6.2mm
  • Connection type: Screw terminals

How to use

The relay is designed for mounting on standard DIN rails within control cabinets. To install, snap the unit onto the rail and connect the control and load wiring to the designated screw terminals. Ensure that the supply voltage matches the 230V AC/DC specification before energizing the circuit. The plug-in design allows for quick replacement of the relay module if maintenance is required without disconnecting the entire wiring assembly.

What to consider before purchase

  • Verify that your control system output matches the 230V AC/DC voltage requirement.
  • Ensure the 6A thermal current rating is sufficient for your specific load.
  • Check available space on your DIN rail to accommodate the 6.2mm width.
  • Confirm that screw terminal connections are compatible with your existing wiring standards.

Usage recommendations

Always ensure that the power supply is disconnected before performing any installation or maintenance work on the relay to prevent electrical hazards. Periodically inspect the screw terminal connections to ensure they remain tight and free from oxidation.
