Product information

Description

The Grenton REL-204-D-01 is a professional relay output module designed for advanced building automation systems. It features four independent relay outputs, allowing for precise control of various electrical devices. The device is housed in a compact enclosure specifically engineered for standard DIN rail mounting, making it an ideal choice for organized control cabinets and electrical distribution boards. By utilizing the TF-Bus communication interface, this module ensures reliable and efficient integration within the Grenton smart home ecosystem.

Advantages

This module offers significant flexibility in managing electrical loads due to its four independent channels, which can be configured to operate separately. The DIN rail mounting design facilitates a clean and professional installation, reducing wiring complexity within control panels. Its robust construction ensures long-term reliability in demanding automation environments, while the TF-Bus connectivity allows for seamless communication with other system components, providing a scalable solution for both residential and commercial building management.

Suitable for

  • Lighting control systems
  • Pump and valve operation
  • Electric heating management
  • General purpose electrical load switching

When it may not be suitable

This module is not intended for switching high-power industrial machinery that exceeds the specified relay contact ratings. It is also not suitable for environments where wireless communication is required, as it relies on a wired TF-Bus connection.

Key specifications

  • Number of relay outputs: 4
  • Mounting type: DIN rail
  • Communication interface: TF-Bus
  • Application: Building automation

How to use

The module should be installed by a qualified professional onto a standard DIN rail within a distribution board. Once physically mounted, connect the TF-Bus communication cable to the designated terminals to integrate the module into the Grenton network. Connect the electrical loads to the relay output terminals according to the wiring diagram provided in the technical documentation. After installation, the module must be configured via the Grenton software environment to assign specific functions to each of the four outputs.

What to consider before purchase

  • Ensure the total power consumption of connected loads does not exceed the relay contact limits.
  • Verify that your existing system supports the TF-Bus communication protocol.
  • Confirm there is sufficient space on the DIN rail within your electrical cabinet.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks to prevent electrical shock and damage to the device.
