Sensor-Technik UK is introducing the ESX-LT programmable universal CAN-bus controller, which is a smaller and lower-cost version of the company's ESX controller for mid-sized vehicle-mounted systems. The weatherproof design and wide operating temperature range make the ESX-LT suitable for off-highway and other construction equipment that has to operate in arduous conditions.
The controller is based on a powerful 16bit microcontroller running at 20/40MHz with up to 1Mbyte of Flash memory, 256Kbyte of RAM and 8Kbyte of FRAM or EEPROM. The standard unit has eight digital inputs, eight multifunction inputs and eight digital or PWM outputs. Each of the multifunction inputs can be programmed to read voltage, current, digital or frequency signals. Expansion units enable the ESX-LT to be specified with up to 28 I/O.
Communications are provided in the form of an industry-standard RS232C serial interface with a programmable baud rate, and one or two CAN-bus interfaces that support both low- and high-speed Controller Area Network communications at up to 1Mbit/s.
Using these communications interfaces, the controller can be freely programmed in C or using a CoDeSys IEC 1131-3 graphical interface.
Featuring a rugged cast aluminium housing measuring just 154 x 169 x 52mm, the compact, fanless ESX-LT controller operates from a 9-32V DC power supply - which makes it compatible with all standard vehicle supplies. Its operating temperature range is -40 to +85degC and the ventilation slots are protected with a Gore-Tex membrane that maintains a continuous electromagnetic screen and environmental sealing to IP65 (optionally IP67).
The unit meets all environmental and EMC requirements of the automotive, agricultural and construction industries, including all requirements for CE marking of completed systems.
