Entrada digital MasterBus

The Digital input MasterBus is an interface module that allows you to integrate standard mechanical switches into your MasterBus network. It converts the physical pulse from a switch into a digital signal to control various compatible devices (lighting, pumps, alarms, etc.).

You can connect up to four single-pole electrical switches to a single Digital Input MasterBus module using the supplied wiring harness.

The module is compatible with most traditional mechanical switches, including standard rocker switches (On/Off) or push buttons (momentary).

No, this module has an IP21 protection rating. It is not waterproof and must be installed in a dry environment, protected from rain, moisture, and condensation.

Event configuration is done via a compatible display such as the MasterView Easy or from a computer using the MasterAdjust software (which requires a MasterBus USB interface).

The Digital Input is very energy-efficient. It consumes only 0.21 mA in standby mode, helping to preserve the most sensitive battery banks on your boat or vehicle.

Yes, by using the Toggle function with a push button. By holding the button down longer, you can vary the intensity of the connected lighting (dimmer function).

The delivery includes the Digital input module, a cable with a connector (harness) to connect the switches, a MasterBus cable, a MasterBus terminator, and the user manual.

This module offers high programming flexibility and allows configuring up to 63 different events on the MasterBus network.

Each input can be configured with five distinct behaviors:

On: turns on at the first signalOff: turns off at the first signalCopy: follows the switch state exactlyCopy Invert: inverts the switch stateToggle: toggles state with each pulse (ideal for push buttons)

The ultra-compact housing can be installed in two ways: surface-mounted on a bulkhead or clipped directly onto a standard DIN rail.

No, never connect a non-MasterBus device directly to the MasterBus network. The Digital input is designed only to read the state of mechanical switches to send digital commands to other MasterBus-compatible equipment.

The module is very compact: it measures 66 x 78 x 32 mm and weighs approximately 80 grams (125 g including the terminator and cable terminal).

Yes, as with any MasterBus network, both ends of the overall network must be terminated. A MasterBus terminator is supplied with the module in case it is placed at the end of the line.

The Copy Invert function makes the target device state the exact opposite of the input switch state. For example, if the physical switch is in the "On" position, the target device turns off ("Off").

Yes, you can integrate multiple modules on the same MasterBus network. It is then recommended to rename each device (for example "Digital in 1", "Digital in 2") via the configuration menu for easier identification.

No, the Digital input does not distribute electrical power. It acts solely as a control trigger. To supply power to loads (lights, pumps), it must be paired with a power module such as the Digital DC 10x10A or the Digital Switching.

To connect the wires from your switches to the terminal block of the supplied harness loom, you will simply need a 2 mm flathead screwdriver.

Yes, there is an Event Lock (Events locked) option that disables configuration changes on the device. This feature is typically reserved for the installer and requires a login ID.

No, the Digital Input module does not require a separate external power supply. It is powered directly via the MasterBus network cables.
