Product Overview

• Part No: NPCT-01C, part code 64009486
• Brand: ABB
• Applicable System: ABB AC500 series PLC, compatible with PM573, PM583 mainstream CPU units
• Type: Independent high-speed pulse counting & timing special expansion module

• FunctionReceive pulse signals from rotary encoders, proximity sensors and pulse transmitters. Complete high-precision pulse accumulation, frequency calculation and time timing; convert pulse data into actual speed, displacement, length values and upload to PLC main controller. Undertake high-frequency signal computing independently to reduce CPU load, realizing closed-loop positioning, speed tracking and fixed-length cutting control for production equipment.
