| Datasheet | Download Datasheet |
The TimeMark 26/SG is a true RMS voltage monitor for 80-550 V AC systems. It measures the true RMS voltage and trips on low or high voltage, each with its own delay or disabled; the relay operation is user selectable.
Trip points: low voltage 80 V to the high set point -1%, in 0.5 V steps; high voltage low set point +1% to 550 V, in 0.5 V steps. Trip delay: 0-20 s (adjustable, high and low independent). Restart: 0-300 s (adjustable). Reset: automatic or manual (selectable).
Output: 2 x SPDT, 10 A at 240 V AC resistive; 4 A general use at 120 V AC; 2 A general use at 240 V AC; C300 pilot duty. Mounting: DIN rail. Approvals: cULus Listed (Industrial Control Equipment). It operates from -29 to +54 °C.
