The powerful electronic compact control unit ESX.4cl-ag is a flagship among the programmable control units in the STW portfolio. It offers extensive functionality in a very compact and robust die-cast aluminium housing. This makes the ESX.4cl-ag suitable for the most demanding applications, particularly in mobile machines with limited installation space. The specially designed SPE interfaces are capable of implementing the new High-Speed ISOBUS standard.

The ESX.4ct is a small compact and freely programmable control unit featuring the latest processor and input/output technologies. With compact housing, it facilitates the automation of small machines and attachments and can also be used as a controller for dedicated tasks in more complex systems. A range of different I/O configurations are available. The inputs can be configured for different functionalities and the half-bridge outputs can also be used to drive PVG valves.

The BCX.4cs-ag is designed as a central on-board control unit for agricultural implements with and without ISOBUS. It handles the protection, distribution, switching and control of the electrical energy on these implements.

Thanks to the certified ISOBUS hardware, nothing stands in the way of operation on the ISOBUS. Alternatively, the BCX.4cs-ag can be operated via a separate display.

In addition to protecting the individual circuits, larger loads, such as lights and motors, can also be switched or controlled directly. Software-configurable multifunctional inputs are available for reading in signals on the attachment.

The cost-optimized ESX.iot works as a CAN slave module and extends the I/O capabilities of a central control unit. Placed close to sensors or actuators the I/O unit helps to reduce installation effort and the cost and weight of the system. It fulfils safety requirements (PL b) and fits perfectly into offroad machinery used in agriculture, forestry, construction, mining, or municipal applications. Integration in STW’s openSYDE software tool ensures intuitive system design.

• Safety Level PL b

• Inputs: 14/18/22 (12 bit, NAMUR support)
• Outputs: 13/9/5 (Half-bridges with PVG support, high-side switches)
• Options: 6-axis accelerometer & gyroscope
