Wired DIN‑rail Relay 230V PS-08M by Blue Tech Controllers, single‑channel 230 V AC

The Wired DIN-rail Relay 230V PS-08M by Blue Tech Controllers is a single-channel electromechanical relay intended for fixed installations on standard DIN rails. Designed for switching 230 V AC loads, this compact module fits into electrical panels and control cabinets and is suitable for basic on/off control in automation, lighting, heating and other building systems. The relay provides a straightforward wired connection and physical isolation between control circuits and mains voltage.

Advantages

This DIN-rail relay offers compact dimensions suitable for crowded distribution boards and compatibility with standard rail mounting. Its single-channel configuration simplifies wiring and integration into existing control schemes. The relay’s electromechanical switching provides clear open/close contact feedback and reliable operation for resistive and inductive loads within rated limits. The wired design avoids wireless or software dependencies, which can be preferable for stable, long-term installations.

Suitable for

• Switching lighting circuits in commercial and residential panels
• Controlling heating elements, boilers or pump circuits
• Basic automation tasks in industrial control cabinets
• Replacing or extending relay outputs in electrical distribution systems

When it may not be suitable

This relay is intended for fixed wired installations and does not include wireless control, program logic, or advanced communication interfaces. It is not designed to replace multi-channel controllers or PLCs when complex sequencing, scheduling or remote monitoring is required. Use caution if your application requires integration with digital bus systems or low-voltage control logic without additional interface modules.

Key specifications

• Channel count: single-channel relay
• Rated control voltage: 230 V AC
• Mounting type: DIN-rail (standard rail profile)
• Contact type: electromechanical relay contacts
• Intended application: switching mains-voltage (230 V) circuits

How to use

Install the relay on a standard DIN rail inside the electrical cabinet. Connect the control and load conductors according to the wiring diagram provided by the manufacturer: line and load to the relay contact terminals, and the control supply to the relay coil or input terminal rated for 230 V AC. Ensure all power is isolated during installation and confirm correct terminal tightening. After wiring, apply power and verify correct switching by activating the control input and observing the load operation. Follow local electrical codes and use appropriate protective devices such as fuses or circuit breakers.

What to consider before purchase

• Confirm that the relay’s 230 V AC control rating matches your control circuit voltage
• Verify load type and current to ensure compatibility with electromechanical relay contacts
• Check available DIN-rail space and mounting orientation in your panel
• Determine whether additional interfaces are needed for integration with automation systems

Usage recommendations

For reliable operation, use the relay within its rated load limits, include appropriate overcurrent and surge protection, and perform periodic inspections of terminal tightness. When switching inductive loads, add suppression or snubber components as recommended for electromechanical contacts to extend service life.
