Frequently Asked Questions
What is the function of this relay output module?
The relay output module is designed to provide 6 potential-free relay outputs that can be individually configured for various control tasks such as continuous or pulse contacts, and can handle different voltage levels on adjacent output points.
Can different voltages be applied to adjacent output points on the module?
Yes, the module allows for different voltages, including AC 250 V mains voltage and SELV/PELV 24 V, to be applied to adjacent output points.
What type of indicators does the module have for input/output status?
The module features individual LED indicators for each input/output point to display the status. The TXM1.6R model has green LEDs, while the TXM1.6R-M model has tri-colour LEDs that can show red, yellow, or green based on the configured function.
Is local override possible with this module?
Local override is a feature available on the TXM1.6R-M model, allowing manual control of the relay outputs in accordance with ISO 16484-2 standards.
What are the mounting options for this module?
The module is designed in a compact DIN format, allowing for easy installation and handling. It can be mounted onto a DIN rail and features a separate connection base and plug-in module for quick replacement without affecting other modules.
How are the relay contacts on the module rated?
The relay contacts are potential-free and are not interconnected, meaning each input/output point must be powered separately. They can handle resistive, inductive, and motor loads with specific current ratings as detailed in the module's technical specifications.
What should be considered when connecting field devices to the module?
When connecting field devices to the module, it's important to ensure that the total power consumption does not exceed the module's capacity and that appropriate fusing is used for protection.
How can the module be identified in a complex system?
The module comes with double-sided labels for easy identification of all input/output points, facilitating easier management and maintenance in complex systems.
What is the power consumption of the module?
The module's power consumption varies depending on the load. It has a base load for its own operation and additional consumption based on the connected I/O modules, KNX PL-Link, M-Bus, and field devices.
How is the module protected against electrical faults?
The module has internal fusing that is irreversible and non-replaceable. For external supply lines, it is recommended to use non-renewable fuses or circuit breakers with specific characteristics to protect against short circuits and overloads.
