M154B Rear of Unit
The M154B10-Y20 Series Control Panels are specifically designed for operation with T4i, T4F, and Stage V Engines equipped with DPF or DPF SCR with DEF. They also serve as a configurable diesel engine control panel for panel-mount, enclosed, or customer-specific installations. With a family of configurations ranging from a panel mount with and without an enclosure and NEMA 4X enclosure, virtually any installation criteria can be met. If a panel or enclosure is not required the M154B series offers a kit containing all necessary parts that can be mounted in a customer-specific panel design.
With a full-featured J1939 interface, the M154B series panels provide a complete interface for virtually any SAE J1939 T4F data, helping support broader engine control systems where reliable data access and operator visibility matter. The M154B provides the most features in its price range.
Practical Monitoring for Tier 4 and Stage V Engines
The M154B Series gives operators clear access to engine data, alarms, regeneration status, speed settings, and diagnostics without overcomplicating the panel.
As part of MBW’s diesel engine monitoring systems, each diesel engine control panel configuration supports practical visibility for T4i, T4F, and Stage V engine applications.
Display
The 2.3″ Graphical high resolution LCD Display provides an easy-to-read viewing area for either a single or dual display of virtually any data.
Throttle Control
A single momentary rocker switch adjusts the engine speed via CANBus communications to the engine. The throttle functionality is user selected, allowing the rocker switch to provide a smooth ramp function or a fixed rpm 2-state setting. This gives operators practical diesel engine control through CANBus communication, with selectable throttle behavior based on the application.
DPF Regeneration Control
The M154B supports all four Yanmar T4F engines DPF Regeneration States; Auto or Reset, Manual, Stationary, and Recovery. Under normal operating conditions, Reset Regens are performed automatically. For Manual, Stationary and Recovery regens, the M154B Series panels provide user friendly on screen instructions.
Standard icons inform the operator of the regeneration status.
Configurable Engine Speed Limits
The M154B Series Control provides the user with two configurable engine speed settings. These speed settings can be set to any engine RPM within the min and max RPM range of the engine. One speed setting for minimum engine speed (i.e. Min RPM) and the other speed settings for maximum engine speed (i.e. engine Max RPM).
Faults
For diesel engine monitoring systems, fault visibility is a key part of daily operation. The M154B displays diagnostic messages from the ECU per the J1939 format. All DM1, DM2, DM12 and DM23 diagnostic messages from the Engine ECU are reported. Engine specific diagnostic messages are available for specified engines. Faults are indicated with either a Red or Amber blinking indicator (determined by severity).
Operator Response Support
Faults, regen prompts, speed limits, and alarms need clear operator action. The M154B brings display data, diagnostics, throttle control, and regeneration prompts together to support practical diesel engine control decisions.
DB Viewer
The Db Viewer feature provides a listing of all data supported by the M154B System and the operator may select which values to be viewed.
Maintenance Timer
User configurable maintenance timer. When programmed, the system provides a warning message when the maintenance timer has expires.
Mounting Template
Optional Expansion Module
The M300DP Dual Programmable I/O control expands the M154B capabilities with 2 additional analog inputs for Oil Pressure, Fuel or Water Level and 2 additional discrete inputs for remotely controlling engine speed.
Enclosures
M154B Series Control Panels are available in 2 different types of enclosures.
- The steel enclosure: .074″ thick CRS with welded seams and powder coated for durability under extreme conditions.
- NEMA 4X enclosure: Fully sealed and weather tight, the NEMA 4X enclosure provides protection from the most extreme weather conditions.

M154B Basic Series FAQs
How do I know if the M154B is the right fit for my engine application?
Share your engine model, emissions tier, panel needs, enclosure requirements, and control expectations so MBW can review whether the M154B fits your diesel engine monitoring systems needs.
Can the M154B be used in a customer-specific panel?
Yes. The M154B is available as a kit when the components need to be mounted into a customer-specific panel design.
What should I review before requesting a quote?
Review engine type, T4i/T4F/Stage V requirements, display needs, speed control needs, enclosure type, expansion needs, and installation layout.
Can the M154B support remote or dual-station applications?
Yes. MBW can review dual-station layouts as part of a custom diesel engine control system, including remote panel needs, extension harness requirements, E-stop placement, and throttle control expectations.
When should I consider the optional M300DP module?
Consider the M300DP when the application needs added analog inputs, discrete inputs, auto-start support, or expanded remote control functions.
