GE Fanuc 8521-LC-MT PAC8000 Logic Controller
The GE Fanuc 8521-LC-MT is a programmable logic controller engineered for process automation and distributed control within the PAC8000 system architecture. Executing control strategies built on IEC 61131-3 programming languages, it provides central control, event logging, and network communications for up to 64 PAC8000 I/O modules.
Communication Interfaces and Controller Performance
The controller operates on a nominal 12 VDC supply (10.9 to 12.6 VDC range) and features dual RJ45 Ethernet ports supporting 10/100 Mbps Modbus TCP/IP communication with 1500 V dielectric isolation. It incorporates a half-duplex RS-485 serial port via a 9-pin male D-type connector with configurable baud rates from 1.2 to 115 kbps. The unit supports network and controller redundancy—accommodating up to 24 simplex or 12 redundant controllers per LAN—and includes internal event recording for up to 8,000 events.
