The ESX®-3XM is the latest freely programmable electronic control unit from Sensor-Technik Wiedemann GmbH. It is conceived specifically for applications in modern mobile machines and off-highway vehicles, and for SIL2 safety relevant applications.

It is the second ESX®family member to be built around a 32 bit processor, after theESX®-3XL. The ESX®-3XM needs around half the space of the ESX-3XL and still offers up to 66 Input/Output channels.

With the 32 bit microcontroller (Tricore TC1796, 150MHz), 6MB Flash, 4MB RAM and 32kB EEPROM it is amongst the most powerful freely programmable control units on the market. A highlight of the ESX®-3XM is the extreme flexibility and scalability. The base configuration is highly configurable through software, and up to 3 expansion boards can be added in any combination (the building block principle).

All inputs and outputs in the base version are configurable. For example the 15 multi-function inputs can, depending on function call, be used as current, voltage, digital or RPM inputs. The 8 high-side outputs are equipped with precise current feedback for current controlled devices and low loss free wheel circuits. All outputs can be switched off via a second path.

The base version is complete with 4 CAN interfaces, a serial interface (RS232, 115kBit), a programmable constant voltage output, two dual color LEDs and a buzzer. All inputs and outputs are protected against short circuits and overloads. Open circuit and overload on the supply pin can also be detected. All analog signals, internal and external, are available as 12bit values with a 2kHz sample rate.

For customer specific adaptation up to three expansion boards can be added, with each accessing 14 pins on the connector, where each pin can be independently assigned a functionality. Several expansion boards are already available, for example for RS232/RS485, RTC, data memory, incremental inputs and PVG/digital/PWM outputs. Development of new expansion boards, also customer specific boards with special functionality, can be completed quickly and simply.

The ESX®-3XM electronics are in a robust and compact diecast aluminium housing, and thereby protected from the rugged environment of agricultural and construction machinery. A proven connector system with secondary interlock forms the interface to the vehicle or machine.

The application software for the ESX®family is quickly and efficiently developed using the ESX®-BIOS either in C/C++ or based on IEC 61131-3 (CoDeSys). Various additional libraries for example for CANopen or error handling simplify integration of the ESX®-3XM.

A comprehensive and clear user manual and inexpensive tool chain complete the total packet.
