GE Multilin 269PLUS-D/O-216-100P-HI Motor Management Relay | Multilin 269 Plus Series
Engineering Background
The GE Multilin 269 Plus series represents GE’s flagship digital motor management platform, engineered for demanding industrial environments where motor protection, monitoring, and control must operate with zero-compromise reliability. The 269PLUS-D/O-216-100P-HI variant integrates discrete I/O expansion, a 216 VAC auxiliary power supply, 100:5 A CT ratio compatibility, and high-interrupting-capacity output relays — making it the preferred specification for heavy-duty motor control centers (MCCs), pump stations, compressor drives, and process-critical applications.
Product Positioning
Designed for procurement engineers and plant reliability teams sourcing verified OEM protection relays for AC induction motors from 0.5 HP to multi-megawatt ratings. The 269PLUS-D/O-216-100P-HI is a direct replacement and upgrade path for legacy electromechanical overload relays, offering integrated SCADA connectivity, event logging, and predictive diagnostics in a single 19-inch rack-mount or panel-mount chassis.

System Architecture & Signal Flow
The 269PLUS-D/O-216-100P-HI operates as a standalone intelligent electronic device (IED) within the motor control circuit. Three-phase current signals are acquired via 100:5 A CTs on the motor feeder cables. The relay’s DSP core computes true RMS values, thermal capacity used, and protection element states on a continuous 4 ms scan cycle. Trip and alarm outputs are routed through the HI-rated output relays to the motor contactor coil and annunciator circuits. RS-485 Modbus RTU port connects to the plant DCS or SCADA host for real-time data acquisition and remote setpoint management. Discrete inputs accept status signals from motor starter auxiliary contacts, thermistor probes, and external interlock circuits.

Technical FAQ
Q: What does the “D/O” suffix indicate?
A: D/O denotes the Discrete Input/Output expansion option, adding additional digital I/O points beyond the base relay for interlock and status monitoring applications.
Q: Is the 269PLUS-D/O-216-100P-HI compatible with 50 Hz and 60 Hz systems?
A: Yes. The relay auto-detects system frequency and adjusts protection algorithms accordingly. It is fully rated for both 50 Hz and 60 Hz motor applications.
Q: Can this relay protect motors driven by variable frequency drives (VFDs)?
A: Yes. True RMS current measurement ensures accurate thermal modeling even with the harmonic-rich output of VFDs. Consult GE Multilin application note AG-2006 for VFD-specific settings.
Q: What CT ratio is required?
A: This model is factory-configured for 100:5 A CTs (100 A primary, 5 A secondary). For different motor FLA ratings, select the appropriate 269 Plus variant with matching CT ratio.
Q: Is Modbus TCP/IP available?
A: The base unit supports Modbus RTU over RS-485. Modbus TCP/IP requires an optional Ethernet gateway module or the 269 Plus Ethernet variant.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume pricing is available for orders of 3 units or more — contact Konmask for a tiered quotation.
