IQAN-MC3 programmable hydraulics controller for safety functionsParker Hannifin is launching the innovative IQAN-MC3 programmable hydraulics controller for OEMs and system integrators developing mobile and off-highway equipment. Forming part of Parker's IQAN family of motion and control products, the IQAN-MC3 enables both safety and operational functions to be controlled from a single module; system design and build times and costs can therefore be reduced, while improving machine performance, safety and productivity.

The launch of the new controller coincides with growing demand from manufacturers of mobile and off-highway equipment for components and software for safety systems complying with functional safety standards such as EN ISO 13849-1 or IEC 61508 (or IEC 62061, the machinery sector standard).

Used in conjunction with Parker's dedicated IQAN Studio Software Tools, the new IQAN-MC3 module enables both operational and safety functions to be programmed, controlled and monitored through a single controller. This helps machine builders minimise the number of components required and reduces the overall system complexity and cost.

To make this possible, the IQAN-MC3 is designed to IEC 61508 (certification pending) and effectively enables the operation and performance level of all safety functions to be proven as part of a SIL2 (Safety Integrity Level 2) methodology, or to be used as part of a PLd (Performance Level d) subsystem within EN ISO 13849-1.

Although the IQAN-MC3 can be used to manage both safety and operational functions, it is always the former that takes priority. The new module can be used as a standalone controller, with local I/O, or integrated within larger systems using four CAN buses. Each module has 16 digital inputs and 16 analogue inputs, all of which can be set for safety-related signals. Additionally, there are four proportional current outputs designed to drive proportional hydraulic valves, with each output controlling one bi-directional valve section, as well as five digital outputs for driving on and off solenoids.

Each MC3 unit is constructed to meet the rigours of mobile and off-highway applications, with a robust enclosure that withstands high levels of vibration and humidity, sealing to IP66 and a design that permits operation at temperatures from -40 to +85degC.

The IQAN-MC3 is designed to be used with Parker's suite of IQAN Studio Software Tools, which allow electronic systems to be developed, programmed, configured and remotely managed. In particular, tools such as IQANdesign and IQANrun give design and production engineers a flexible, powerful and easy to use set of modular tools that can significantly reduce development, construction and subsequent maintenance times.
