Model Interpretation

CC=C300 C-series control card; PCNT=Process Control CPU;02=2nd generation upgraded high-performance processor version.

Technical Specifications

Power:24VDC backplane, rated current 320mA, power consumption 7.9W

Memory:64MB Flash+32MB ECC RAM (error correction), anti-data corruption

Dual optional scan cycle:20ms/50ms; dual I/O Link optional speed 375Kbps/750Kbps, single link expands more I/O bases

Ambient:-20℃~+60℃,5%~95%RH non-condensing; Class I Div.2 hazardous area approval, CE/UL certified.

Interface and Communication Configuration

Front same LED layout as PCNT01; rear rack backplane connection, dual redundant FTE 10/100Mbps Ethernet ports; optimized internal bus for large-capacity I/O data transmission, fully backward compatible with original C300 rack and all C-series I/O modules.

Core Function

Support high-speed fast loop control under 20ms cycle, adapt to fast-response process such as furnace, compressor anti-surge control; inherit all PCNT01 control algorithm including ProfitLoop advanced PID.

Enhanced redundant switching speed, shorter bumpless transfer time; larger control logic capacity for complex batch S88 production control.

Advanced self-diagnosis, detailed fault location of CPU, network and I/O link, support online firmware upgrade via Experion software without module replacement.

Applicable Scenarios

New-built petrochemical, coal chemical, LNG DCS main control rack, power plant boiler & turbine critical control cabinet, pharmaceutical batch production automatic control system.

Operation and Maintenance Instructions

Full hot swap; compatible with all existing C-series IOTA bases and analog/digital/HART I/O cards; system upgrade from PCNT01 to PCNT02 only needs software configuration modification, no cabinet wiring change.
