GE 369-HI-R-M-0-P-0-E

Product Introduction: This is a high-performance protective relay module from the GE Multilin 369 series. The “HI” designation indicates a high-impedance voltage input configuration, specifically designed for direct connection to potential transformer (PT) secondary circuits without requiring intermediate matching transformers. The “R” indicates relay output, “M” indicates manual reset capability, “0” indicates DC power supply (typically 125V DC or 250V DC), “P” indicates RS-485 serial communication port, “0” indicates no Ethernet port, and “E” indicates enhanced binary I/O configuration. This module is a core component in medium voltage motor and transformer protection schemes.
