| Datasheet | Download Datasheet |
The TimeMark 171 is an undercurrent monitor for 0.1-1 A AC. Its relay picks up once the current is 5% above the drop-out setting, after the restart delay, and drops out when the current stays at or below the setting for longer than the trip delay.
Sensing: direct, through an internal shunt (fuse the circuit at 10 A max). Control supply: 120 V AC. Trip point: 5% above the drop-out setting (fixed). Drop-out: 0.1-1 A (adjustable). Accuracy: +-0.5% of set point. Trip delay: 0.1-10 s (adjustable). Reset delay: 0.1-300 s (adjustable). Reset: automatic.
Output: 1C SPDT, 10 A at 240 V AC resistive. Mounting: plug-in. Indicator: FAULT (red LED), RUN (green LED). It operates from -29 to +55 °C.
