Control Units
C48.N21.XOUT
C48.N21.XOUT is a mid-scale programmable CANbus ECU for mobile machinery and on-vehicle equipment. With 21 inputs and 16 outputs, it provides centralized control of sensor, hydraulic valve and relay infrastructure. CANopen and SAE J1939 support, dual-microcontroller architecture and EN ISO 13849-1 PL/d safety performance make it a reliable control solution for field conditions.

Technical Details
C48.N21.XOUT is a mid-scale control unit in the C48 class of the Avioni programmable ECU family. It is chosen when C24.XOUT’s 8+8 channel capacity is insufficient, but HE-class or high-channel MUX ECUs are not required. It is designed for sensor reading, output driving and safety logic in aerial platforms, mobile cranes, construction machinery, concrete pumps and CAN-based multiplex systems.
Input and Output Capabilities
C48.N21.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. Field elements such as limit switches, pressure sensors, joystick signals, angle/length sensors (ALX, 3X) and hydraulic proportional valves can be managed from a single unit.
Safety and Reliability
Like all Avioni master ECUs, C48.N21.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 the relevant standards under EMC Directive 2014/30/EU.
CANbus Communication
C48.N21.XOUT features a CANbus interface supporting CANopen and SAE J1939 protocols. It can operate as master or slave in multiplex systems and integrates on the same network with C24, C32.MUX and other Avioni module units, AVD HMI displays and third-party CAN devices.
Javelin Suite Integration
C48.N21.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
• 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 C48 Family
C24.XOUT (8+8) is the most compact entry level. C48.N16.MUX (16+16) is a fixed-ratio MUX module. C48.N21.XOUT (21+16) is the mid-scale XOUT model offering more inputs and programmable outputs. C48.AERO (19+9, 2× CAN) is specific to aerial work platforms; C48.N21.XOUT suits general-purpose mobile machine control. Higher channel needs scale to C72.MUX, C80.XOUT or C121.XOUT.
Typical Applications
• Mobile crane and aerial platform control systems
• Construction machinery and concrete pump control panels
• Hydraulic valve, relay and warning lamp driving
• Limit switch and sensor aggregation
• CAN-based multiplex machine architectures
• Prototype development and series production commissioning
