Your choice depends on four elements: function, number of channels, power supply, and installation point.
In short: Do not choose the module based only on the number of outputs: always check the wiring diagram, voltage, current, and physical control.

How to read the model suffixes
- The letters E identify versions intended for the power supplies specified in the relevant technical sheet.
- The letters F identify 12 V versions: always check the model sheet.
- The A/B and C/D variants of four-channel modules differ by power supply and installation point.
When to choose a MINI version
- The module must be installed behind a switch or in a 502/503 wall box.
- You need to control one or two circuits.
- The available space and wiring are compatible with the model dimensions.
When to choose a DIN version
- The system is centralized in a junction box or panel.
- You need to manage multiple circuits from the same point.
- The existing wiring already reaches the panel or technical box.
This table helps guide your choice but does not replace electrical verification. Before purchasing, always compare the technical sheet and wiring diagram of the model.
