MPB 44 M master controller
Universal traffic light system for flexible control of up to maximum
12 signal groups, for example at pedestrian crossings with request
function as well as vehicle-actuated alternating one-way traffic,
T-junction or crossroads situations, possibly with additional turning
lane, blinking light or waiting signal. The MPB 44 M/S series is based
on the outstandingly proven MPB 4400 system which has been
popular for many years. Operation is also the same so that no relearning
is necessary. Depending on the technical features, already
existing MPB 4400 traffic lights can be simply integrated in the new
system.
The MPB 44 M controller is equipped as follows:
• central emergency-off switch for the complete traffic light system
• residual current-operated device (RCD switch)
• digital AC metre showing the 230 V energy consumption
• 230 / 42 V transformer for central power supply to all signal heads
directly from the controller via the data cable
• programming of up to 4 groups directly in the controller via the display
• selection switch for immediate manual traffic light control for
manual mode, blinking lamp, lamps off and continuous red
• programming interface for 12 signal groups (laptop connection)
• connection for an external printer or laptop (USB and serial)
• freely accessible 230 V service power socket
• connection for parallel signal head and SMS messaging module
• synchronous input for coordination of progressive signalling
• automatic mains / battery changeover for 12 V battery operation
• MPB 44 S control PCB for the first carriageway signal head

MPB 44 S slave signal head
equipped in each case with its own MPB 44 control PCB that also
covers the connected additional equipment and communicates with
the central MPB 44 master controller via one cable for databus and
42 V power supply. All signal heads are equipped with LED technology
and a 42 V AC/12 V DC power supply unit. There is also a connection
for 12 V power supply with automatic changeover for possible battery
operation of the signal head. All carriageway signal heads are
prepared for directional radar detectors for vehicle-actuated traffic
light control or for our PB-CAM as video detector for registering
traffic volumes. There is also an output for a parallel signal. A request
traffic light for pedestrians is provided by plugging request buttons
directly into the signal head without needing additional wiring from
the button to the controller (holder included in the scope of supply).

Just one single cable is needed to operate the MPB 44 system.
Just one cable is now responsible for data transfer between master controller and the individual slave signal heads in
up to 12 groups together with the central 42 V power supply from the controller, thus clearly minimising the wiring workload
on site (see diagram). No extra cables are needed for power supply, detectors, buttons and data bus so that this one-cable
solution saves lots of time and costs in installing and dismantling the traffic light systems.
