TTC 2300 is TTControl’s latest product family of rugged electronic control units, designed not only to meet the requirements of todays, but also of tomorrow’s mobile machinery. The TTC 2300 electronic controllers are designed for use in demanding safety-relevant applications. The product variants TTC 2310, TTC 2380, TTC 2385, and TTC 2390 fulfill safety requirements up to SIL 2 (IEC 61508), PL d (EN ISO 13849), AgPL d (ISO 25119), ASIL C (ISO 26262) and MPL d (ISO 19014) and are TÜV Nord safety certified. The family members can be programmed either in C-language API or with Codesys Safety SIL 2, including also support for CANopen Safety controller.

Integrated PXROS real-time operating system with multi-core support The TTC 2300 product family is delivered with a real-time operating system providing a high level of application robustness and responsiveness to safety events and can either be programmed in C language or in Codesys Safety SIL 2. The mixed-criticality support allows safety-related and non-safety-related code to be executed on the same CPU without reducing the overall safety level. This leads to low development costs of the mobile machinery electronics and fast time to market.

Rich and flexible I/O set

Up to 60 highly configurable I/Os are available and can be initialized at the application level as different types of inputs or outputs. Beside analog and digital timer inputs, the ECU is also equipped with HS PWM and PVG outputs. This ensures that the various hydraulic valves used in the off-highway machines can be controlled, making the TTC 2300 the perfect fit for hydraulics control. Part of the design are several current measurement feedback loops and plausibility checks, which enable runtime self-diagnosis of the vehicle and various safety architectures. For connection of smart sensors, up to four SENT interfaces (compliant with SAE J2716 standard) with Short PWM Code (SPC) support, are available and enable cost efficient transmission of sensor data to the ECU. Dedicated LED outputs allow control of the vehicle LEDs as well as four full H-bridge interfaces allow the control of electric motors.

High-speed connectivity

Beside of four CAN FD interfaces (bit rate of up to 2 Mbit/s), featuring wake-up over CAN and Isobus compatibility, the TTC 2300 is equipped with one LIN and two Ethernet (100BASE-TX) or two automotive Ethernet (100BASE-T1) interfaces on dedicated high-speed signal connectors.

CAN features:

  • Up to four CAN FD interfaces (bit rate of up to 2 Mbit/s)
  • Wake-up over CAN
  • Isobus compatibility
  • To reduce cabling efforts, a built-in CAN termination configurable via a connector-pin is available
