The TimeMark B292 is a frequency monitor for 120 V AC (90-130 V AC) systems. Its relay stays energized while the line frequency is between the high and low trip points, which are set with binary-coded switches, and drops out outside them.
Frequency range: 45-1023 Hz. Trip points: underfrequency set with ten binary-coded switches (1-512 Hz); overfrequency set with ten binary-coded switches (1-512 Hz). Trip delay: 1 s. Reset: automatic.
Output: 1C SPDT, 10 A at 240 V AC resistive. Mounting: surface mount, screw terminals. It operates from -7 to +50 °C.
