The IQAN-MC41 controller is the lowest I/O count module in the MC4 family. It is best for
smaller applications such as task-oriented control, implementing single features on a vehicle (e.g. valve driver for auxiliary hydraulic function) 
The IQAN-MC41 is designed to be either an IEC 61508 SIL2 Functional Safety (-FS) variant, or a performance optimized, standard controller.
The 3 core CPU architecture of the IQAN-MC41 provides computational power that allows it to perform high speed (ex. 1 ms) control loops for time critical functions. Lockstep CPU and hardware redundancy offers very high real-time performance in safety critical applications.
There are Voltage inputs in 2 different scales, Current loop inputs for 4-20 mA, Timer inputs (used
for frequency, PWM and pulse devices) and Digital (on-off) inputs. Voltage and Timer inputs share pin positions with Digital inputs.
The IQAN-MC41 has 2 double proportional outputs for controlling valves. These outputs can control up to
2 bi-directional proportional valve sections or 2 single solenoid devices (ex. proportional cartridge valves).
The unit also has 4 high-side PWM outputs and 4 low-side PWM outputs.
The IQAN-MC41 footprint is small enough for any installation. The enclosure is rated IP66 + IP69K and is a rugged mechanical design, sealed for outdoor use.
To meet the environment found in mobile machines the MC41 uses a 66 position Molex MX123 high reliability
connector, made for harsh environment and high vibration applications.
