Control Units
C121.XOUT
C121.XOUT is a top-tier programmable HE (Heavy Equipment) CANbus ECU for complex mobile machinery and vehicles. With 60 inputs and 40 outputs, it centrally manages extensive sensor, valve, relay and actuator infrastructure. Three independent CAN interfaces, dual-microcontroller architecture and EN ISO 13849-1 PL/d safety performance make it a reliable master control solution for large-scale LMI, aerial platform and VCU applications.

Technical Details
C121.XOUT is one of the highest-channel master control units in the HE (Heavy Equipment) class of the Avioni programmable ECU family. It is designed for centralized control, safety logic and CAN-based system integration in large mobile cranes, multi-function aerial platforms, fire trucks, concrete pumps, electric vehicles (VCU) and complex multiplex machine architectures. Sixty inputs and forty outputs allow extensive field infrastructure to be managed from a single unit.
Input and Output Capabilities
C121.XOUT can be configured with the input and output types supported by the Avioni ECU platform. In addition to digital I/O, sensor interfaces such as 0–5 V and 0–30 V analog voltage, 0–20 mA current, frequency/RPM, resistance, quadrature encoder and duty cycle measurement, and actuator drive options such as high/low-side PWM, ratiometric voltage and frequency output can be used according to project requirements. Many field elements such as limit switches, pressure transducers, joysticks, angle/length sensors (ALX, 3X), loadcells (PL1000) and hydraulic proportional valves can be coordinated from one master ECU.
Three-CAN Network Architecture
C121.XOUT provides three independent CANbus ports. This supports network segmentation in complex machines and simultaneous management of HMI displays, sensor modules, motor controllers and diagnostic devices. Each port supports CANopen and SAE J1939 protocols. As master in multiplex systems, it integrates with C24, C48, C72 and other Avioni slave/module units, AVD HMI displays and third-party CAN devices.
Safety and Reliability
Like all Avioni master ECUs, C121.XOUT uses a dual-microcontroller architecture for cross-checking of input and output behavior. Over-current protection, over-voltage protection, reverse polarity protection and an internal watchdog safety relay are provided as standard. Diagnostics and current feedback on all inputs and outputs help detect conditions such as wire breaks, short circuits or faulty actuators at an early stage.
The unit is designed and tested to meet EN ISO 13849-1 at performance level PL/d. It carries CE marking and has been verified against EN 55022, EN 55024, EN 61000-4-2, EN 61000-6-1 and EN 61000-6-3 under EMC Directive 2014/30/EU.
Javelin Suite Integration
C121.XOUT is configured and commissioned with Avioni Javelin Suite engineering software. The following operations can be performed via Javelin Suite:
• Application software upload and updates (firmware)
• I/O mapping and parameter configuration
• Safety logic and function block definition
• System calibration and functional testing
• Live CAN data monitoring and debugging
• Reading fault codes and diagnostic information
• Project file management and field configuration
With UCAN-USB or UCAN-BT adapters, Javelin Suite provides wired or wireless access in workshop and field environments.
Position in the ECU Family
C24.XOUT (8+8) is the entry level for compact applications. C48 and C72 series cover mid-to-high channel needs. C80.XOUT (37+32, 2× CAN) and C121.XOUT (60+40, 3× CAN) are preferred for large-scale master control requirements. C121.XOUT is the top-end solution for the most complex machine architectures where many sensors, valves and warning outputs are managed from a single center.
Typical Applications
• Large mobile crane LMI and safety limit control systems
• Multi-function aerial work platforms
• Fire trucks and special-purpose heavy-duty vehicles
• Concrete pumps and long
