Manual

General contact

is the default setting and allows you to document any connections between the contacts of the DIN-rail devices and the terminal blocks.

Switching channel (normally open contact)
Switching channel (normally closed contact)

‘Classic’ Switching channels that are inserted into the wiring diagram. With this type of channel, the terminal block connects to the wires of the element above it (usually the L of a protection device in the 230V section or, depending on the terminal type, the (+) or (GND) of the power supply unit in the 24V section.

Dimming channel (230V)

Similar to the switching channels, a dimming symbol is connected to the L of the protection device above it. This type of dimming channel can only be assigned to 230V terminal blocks.

Dimming channel (24V / GND)

A dimming channel of an LED controller. This connects to the GND of the power supply unit above it.

Binary input (external 230V)

A binary input that is triggered by an external 230V signal.

The tool currently assumes that the binary input performs the measurement behind the push-button and always connects the channel to the N of the protection device above it.

Binary input (external 24V, measurement on GND)

A binary input that is triggered by the 24V signal from an external voltage source.

The tool currently assumes that the binary input performs the measurement behind the button on the GND signal and always connects the channel to the GND of the power supply unit.

Binary input (potential-free, 24V+, voltage source)
Binary input (potential-free)

Both channel types can be used to graphically represent a potential-free binary input. The voltage source of the binary input can be assigned to several wires in the terminal block; the actual binary inputs are usually assigned individually.

Tip: Some binary inputs (e.g. Weinzierl 411, Homematic eQ-3) provide individual channels with positive potential in order to summarise everything behind the push-buttons on a common GND.

This type of binary input cannot be mapped with the channels presented here. Instead, “General contacts” (see above) should be configured for this type of binary input. These can also be linked multiple times, for example to represent the combined GND.
