IC690RFH008 function:

l Speed control: speed up, over-critical, variable speed control function

l Compressor control: constant air pressure, constant air volume, static lobe control, anti-surge control.

l Interlock protection: start-up interlock, overspeed protection, anti-backflow protection, stop output

l Auxiliary control: body monitoring, auxiliary control

IC690RFH008 features:

l Extensive redundancy technology: double redundancy of main control unit, power module, network, etc., double or triple redundancy of important signals.

l Anti-surge control: the control cycle is less than 30ms, which meets the real-time requirement of surge control.

l Valve position control: it comes with the function of serving and releasing, and can directly control the electro-hydraulic converter such as DDV valve and VOITH valve.

It has perfect online debugging and simulation function.

l Seamlessly connects with Hollis DCS system to realise the integration of the whole plant management and control.

l Conforms to IEC61131-3 standard configuration language.

IC690RFH008 control system performance index:

l Control range: disc speed ~ 6500r/min (optional), control accuracy: 0.05% rated speed.

l Average trouble-free time: >100000h (hours)

l Control cycle: <100ms (including surge control <30ms)

l System availability rate is not less than 99.9%.

l AC dual-channel power supply; 1+1 equal-current redundancy of power supply devices in the cabinet, with a load rate of 50%.

l Each type of I/O measurement point in the cabinet has more than 20% of spare capacity, the normal load rate of CPU is not more than 20%, the normal load rate of network communication is <20%, and the peak load is about 40%.
