The IQAN-MC4x family of master controllers from the Electronic Controls Div. of Parker Hannifin is designed for hydraulic systems in vehicles and machinery using a 12/24 Vdc power supply. Three different versions handle a wide range of system requirements. The IQAN-MC41 is for economical task-oriented control; the MC42 for mid-size applications and I/O distribution; and the MC43 provides large centralized control.
All the units share the same pinout and software for easy upgrading or scaling of applications. They permit up to 50 inputs (analog, timers, digital) and 36 outputs (PWM and digital). The MC4 family also supports CAM, Parker’s proprietary circuit regulator that ensures consistent and precise control of proportional mobile valves.
There are five CAN and Ethernet ports for in-vehicle networks and diagnostics. And in addition to common voltage, digital and frequency inputs, the MC4x family also includes 0-35 V and 4-20 mA inputs, giving OEMs greater freedom in selecting sensors for specific tasks.
The MC4x architecture includes a powerful, lockstep CPU and hardware redundancy for high real-time performance and cycle times as fast as 1 msec. SIL2-rated versions for functional safety implementation will be introduced later this year. The MC4x devices have up to 1.5 MB application memory and 2 MB log memory for complete machine control and future expansion, if needed.
The MC4x family is compatible with existing IQAN applications, and its IQANdesign software platform is used for programming, simulation, testing and maintenance. This helps ensure fast OEM development and better up-time in the field.
The hardware is built for rugged, high-vibration mobile environments and uses reliable Molex MX123 connectors. The enclosure is rated IP 66/69K and sealed for outdoor use. Finally, the IQAN-MC4x controllers measure only 6.1 × 6.5 in. (155 × 166 mm) for ready installation in tight spaces.
