279CA-120V
The Model 279CA-120 DC Current Monitor provides precise current monitoring for industrial applications. Operating with a 120VAC supply, it handles a 0.1-1 Amp current range with a 1% maximum repeat accuracy. This device ensures operational stability across a -20° to +131° F temperature range. Its robust design includes transient protection up to 2500 VRMS for 10ms, safeguarding critical systems. The unit features a mechanical relay life of 10 million operations, contributing to extended service intervals and reduced downtime. Users can select between automatic or manual reset functions and adjust hysteresis from 0% to 100% for tailored control. This monitor is engineered for reliability in demanding environments, offering consistent performance and system protection. Its compact dimensions and 11-pin socket compatibility facilitate integration into existing control panels, enhancing system efficiency.
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 units have an input frequency of 50/60 Hz. The
standard version, the 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 279C, has a remote trip
adjustment and a remote reset button. An LED indicator is provided on
both versions to indicate when the relay is energized (current above the
trip setting. ) The 279B plugs into a standard 8-pin octal socket; the
279C plugs into a standard 11-pin socket.
