The MasterBus Digital Input 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 simple 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) and push buttons (momentary).

No, this module has an IP21 ingress protection rating. It is not waterproof and must be installed in a dry environment, protected from rain, humidity, 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 linked to a push button. By holding the button down longer, you can adjust the intensity of the connected lighting (dimmer function).

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

This module offers extensive programming flexibility and allows configuration of up to 63 different events on the MasterBus network.

Each input can be configured for five distinct behaviors:

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

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

No, you must never directly connect a non-MasterBus device to the MasterBus network. The Digital input is only used 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 global 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 allows the target device to assume the exact opposite state of the input switch. 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 to identify them more easily.

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, you will only need a 2 mm flathead screwdriver.

Yes, there is an Event Lock option that allows disabling configuration changes on the device. This function 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.
