| MODEL 279 DC Current Monitor |
| Series Description: The Model 279 DC Current Monitor is a single set-point DC current monitor. It can sense either 1-10 Amps DC (24VAC or 120VAC) or 0.1-1 Amps DC (120VAC). The standard version, the Model 279B, has a screwdriver adjustable trip and hysteresis setting on top of the device. The hysteresis setting adjusts from 0% to 100%, and can be set fully clockwise for manual reset operation. A remote adjust version, the Model 279C, has a remote trip adjustment and a remote reset button. The Model 279B plugs into a standard 8-pin socket, while the Model 279C plugs into a standard 11-pin socket. An LED indicator is provided on both versions to indicate when the relay is energized (i.e. current is above the trip setting). |
