Multiplex System - Model M36 (36 Power Outputs)

ECX provides solid state multiplex controllers that are engineered to provide excellent benefits for a number of different industries. These controllers are utilized in emergency services, industrial vehicles, and in commercial buildings.

Benefits of a multiplex system:

  • Reduce the overall cost and installation time of your electrical system
  • Allow for greater customization and ehanced communication between devices
  • Minimize the space and weight of your electrical system

Outputs can be activated as a result of different combination of inputs. This logic is programmed by the customer with the easy to use software developed by ECX (Model ECX-PGM) or it can be factory programmed by ECX with a customer supplied operational description.

M36 Module Description

General technical characteristics:

  • All outputs are rated at 20A and can be customized to operate at 12V or GND
  • Standard configuration is 32 Solid State Outputs (+12V at 20A) (with customer programmable overcurrent protection)
  • Standard configuration is 4 Solid State Outputs (+12V or GND at 20A) (with customer programmable overcurrent protection)
  • 32 Digital Inputs (12V or GND activated)
  • 7 Analog Inputs (0 to +12V)
  • All outputs can be programmed for PWM operation
  • Industrial temperature range (-40°C to +85°C)
  • Reverse polarity, over voltage and load dump protection
  • Low key-off current drain
  • Low input current requirement for digital signals (under 10mA)
  • Large design safety factors for reliable operation
  • Simple plug-in connection of all control and power wiring
  • 2 Independent CAN Buses
    • The first CAN Bus is used for connecting to the vehicle's CAN highway.
    • The second CAN Bus is used for data communications between the control system and individual peripherals (graphic screens, smart switches, etc.)
  • 9VDC, 700mA supply to customer's electronic instruments


Some of the typical operational functions include:

  • Logic functions relating inputs and outputs
  • Pulse width modulation (PWM) on any output
  • Implementation of any number of flashing patterns with multiple flashing schemes (limited only by the number of outputs available)
  • Load management and load sequencing operations
  • Engine throttle control
  • Implementation of logic functions based on information derived from the vehicle's CAN Bus
  • Implementation of time delayed operations
  • Dimming of lights
  • Complete HVAC control
  • Interaction with graphic panels for display information and control signals
  • Oxygen pressure monitoring and alarm
  • Open door indication and alarm
