Structural Characteristics Standard plug‑in module for Series 90‑30 rack slot Front‑panel multi‑LED status indicators Front accessible RS‑485 terminal block Backplane gold‑finger bus contact Mechanical locking latch for module fixation
Working Principle Complete hardware self‑diagnosis after power‑on. Execute stored user program cyclically. Read input data via backplane bus, finish logic calculation, send output commands to I/O modules. RS‑485 port completes program download and data interaction. Diagnostic circuit monitors hardware real‑time status.
Installation Requirements Insert into dedicated CPU slot of main backplane rack. Strictly implement protective ground. Use shielded twisted‑pair for RS‑485 cable, separate from high‑voltage cables. Power off rack before module replacement, hot‑swap not supported. Keep ambient temperature and humidity within rated range.
Usage Notes Do not input over‑voltage to communication terminals. Keep cabinet clean to avoid poor gold‑finger contact. Check LED indicators regularly. Program upload/download uses GE official software. Forbid on‑site disassembly. Keep away from corrosive gas, liquid splash and oil mist.
