Parker’s IQAN-MC3 is a rugged SIL2 rated master safety module that can be used as a standalone mobile controller, as a single bus master, or together with other IQAN master modules.

All IQAN modules are designed with the functional safety requirements of mobile machines in mind. The IQAN-MC3 is especially suited for mobile machine applications with higher demands on functional safety, where there is a need to prove the safety integrity of each implemented safety function.

It is designed in accordance with IEC 61508, and can be used to implement safety functions of up to SIL2. When applying EN ISO 13849-1 for safety functions, it can be used as a PLd subsystem.

The correct operation of the IQAN-MC3 is monitored internally by its Tricore processor and the integrated co-processor. All outputs have diagnostics for both internal and external faults, and have return switches that provide a redundant shut down path.

• Suitable for connection to output subsystems of category B, 1, 2, 3 or 4 in accordance with EN ISO13849-1, up to PLd. For flexibility, the inputs can be configured either in pairs for safety functions, or as single inputs for normal functions.

• Suitable for connection to input subsystems of category 2 or 3 in accordance with EN ISO13849-1, up to PLd.

All of the 32 inputs on the IQAN-MC3 can be used for safety related signals, when the inputs are configured in pairs. There are analog inputs for 0-5 V signals from e.g. hall-effect or potentiometer sensors; digital inputs for e.g. switches; and frequency inputs.

All of the outputs on the IQAN-MC3 can be used for safety related signals. There are four proportional current outputs designed to drive proportional hydraulic valves, where each output controls one bi-directional valve section. The unit also has five digital outputs for driving on-off solenoids.

IQAN-MC3 has 4 CAN buses to communicate with IQAN modules or other CAN devices (supports SAE J1939, CANopen and other protocols). The enclosure is designed to protect the electronics in a harsh environment on mobile machines and has environmentally sealed connectors for use in the outdoor environment.

The IQAN-MC3 SIL2 master controller performs data logging and has full diagnostic and CAN gateway capability. Machine applications for the MC3 are simple to create with the easy-to-use IQAN programming tools. This makes the IQAN-MC3 master controller a perfect fit for any safety related mobile machine application.
