The GIC DMS110 is a digital phase sequence and phase failure relay for 3-phase supplies from 145-500 VAC. It safeguards motors and panels against reversed sequence and loss of phase with a robust changeover output.
🔧 Technical Highlights:
- Supply Voltage: 145–500 VAC
- Functions: Phase sequence (rotation) and phase failure monitoring; some models also detect phase asymmetry
- Timing Range: ON delay selectable 0.5–15 s (model specific)
- Output Contacts: 1 C/O or 2 C/O (depending on variant)
- Contact Rating: 5A @ 250 VAC / 28 VDC (resistive)
- Adjustable ON/OFF delays
- LED indication
- Compact DIN rail design
✅ Benefits:
- Prevents damage from incorrect rotation or single phasing
- Simple wiring and fast commissioning
- Reliable switching via changeover contact
🚀 Applications:
- Pumps, fans and compressors
- Conveyors and machine tools
- MCC and OEM control panels
DMS110 delivers essential 3-phase rotation and phase-loss protection with a single changeover output.
