Module for DIN-rail relay REL08 - Qbus

Module for DIN-rail, suitable for switching eight devices. The relay module has 8 potential-free, change over contacts which can each connect max 16A at 230V (cosj=1). These are 8 independently working contacts that can each be allocated an individual function by means of the software.
The relay module does not have any specific function. It can handle all switching functions : mono-stable (bell), bi-stable (on/off), timer, interval, shutter operation, blinds etc.

Therefore this module can be combined for motor controls and for lighting.
In the case of heavy inductive loads (TL lamp transformers) with a high capacity or bipolar applications, contactors need to be added. The relay module contact then activates the coil of the contactor.

Each module has 2 unique serial numbers (6-digits) enabling programming anywhere and anytime. The 1st serial number refers to the 4 upper contacts, the 2nd serial number refers to the 4 lower contacts.
All programming remains internally stored in a nonvolatile memory. After a voltage cut off, the outputs return to their latest position.
A bipolar automatic fuse of a maximum of 16A must be placed on the mains power
The REL08 contains 8 outputs of each max 16A to control lighting, shutters, power plugs,…
For shutter/blind/curtain control.
This module in an installation is an integral part of the complete home automation system, requiring a CTD controller to communicate.
It is recommended to use an electric cable with conductors of at least 2x1mm2 as the BUS connection.
