The Latest M-Series Product Expands the Options for Off-Highway Controls

The newest off-highway control in the DSE family, DSEM240, is a CAN slave unit designed to work alongside other controllers to provide additional I/O’s to help meet the demands of more complex systems. A versatile controller designed for superior flexibility and performance, the DSEM240 is compatible with all DSEM-Series controllers or any CAN Open /J1939 device, and will help create a bespoke solution for any off-highway or vehicle application.

The new DSEM240 is available in both CANOpen and J1939 variants and replicates many of the features of its DSEM-Series brothers. Designed specifically for the robust environment of the mobile industry, the controllers provide a number of features, which make the products ideal for a wide variety of applications:

·      Fully configurable I/Os with inputs offering digital and analogue capability and outputs offering digital, PWM and PWMi capability

·      Output current monitoring

·      Wide operating temperature -40oC to + 85oC

·      IP67 rating for superior protection against ingress of dust, water and other contaminants.

·      EN, ECE and ISO testing for shocks & bumps, vibration, salt spray, EMC and electrical safety

·      Specialised breather to equalise pressure and reduce condensation

·      Robust aluminium die-cast housing for the toughest environments

Displays enable full control through one device

DSEM-Series include a range of programmable displays designed to work either alongside the controllers or as stand-alone products.  The DSEM870 and DSEM840 offer a choice of fixings for in-cab or panel mounting to suit multiple operator locations.

The displays provide a user interface for controlling equipment through a robust, optically bonded, colour screen and button fascia. Many of the standard switches and controls that are normally found within the cab or control panel can be incorporated into the on-screen functions, to enable full control through one device if required, leading to a simplified system design.

The fully programmable screen presents clear information in a combination of text, graphical, numerical and icon formats providing the user with quick and easy access to equipment operational functions.

Designed for instantaneous operator response times the controller incorporates powerful ARM processors with plenty of memory for the most complex applications. Features include camera inputs for improved operator visibility, multiple configurable inputs and outputs, independent CAN interfaces for J1939, CAN Open and Raw CAN, and Ethernet communications.  

The displays are highly robust and reliable throughout the harshest environmental conditions including humidity and extreme temperatures, and are IP67/NEMA 6 rated.

Proven across multiple applications. 

The proven success of DSE’s UK manufacture & design is evident in the growing number of applications across the world, in which the products are being used. Some such examples are as follows:


The harsh environment of the various mines on the African continent has not been an obstacle for the DSEM-Series, with a number of OEMs integrating them successfully into multiple applications within mining environments.

Emergency Vehicles

Fire appliance OEMs worldwide are incorporating DSEM-Series controllers, displays and battery chargers into their emergency vehicles. Whether the appliance requires amidships or a rear pumping configuration the DSEM-Series is being successfully utilised, providing a level of control suited to the application from simple manual control up to full closed loop control managing the full demand of the system.  High, low and compound (vacuum) pressures are monitored to provide the required pressure set point.

Quarrying, Construction and Recycling

Quarrying, mining and recycling has become a significant growth area for DSEM-Series as a result of Hillhead 2018 where DSE customers were giving impressive working demonstrations of their equipment with integrated DSE control solutions.

Airport Ground Support Vehicles

DSEM-Series Displays are being included in ground support vehicles, which come into close proximity to the aircraft such as mobile passenger steps. Sophisticated features including the camera inputs will aid the operator and prevent aircraft bodies from being touched by the large equipment, preventing unnecessary delays.

DSE’s team of dedicated design engineers are committed to providing the highest quality solutions. Combining their extensive off-highway industry knowledge with their design and manufacturing expertise, has led DSE to create a range of trusted control options that allows optimum utilisation of the equipment or vehicle.  For more information please refer to the DSE website:
