Product overview
GIC DMA220 SM800 Digital Supply Monitoring Relay
The DMA220 is the auxiliary-powered model in GIC’s SM800 series, designed for configurable voltage, frequency and phase monitoring in three-phase control systems. A backlit LCD shows live measurements and fault information.
Key Features
- Configurable for three-phase, three-wire or three-phase, four-wire systems.
- Monitoring of under/overvoltage, under/overfrequency, phase loss, phase sequence and phase asymmetry.
- Neutral-open monitoring for three-phase, four-wire systems.
- Two separately programmable changeover outputs with selectable fail-safe/non-fail-safe and manual/automatic recovery modes.
- Adjustable ON/OFF delays, password protection and a history of the last five faults.
