BWI Eagle, 11-8102, I.S. Optima 2 Dual Channel Speed Switch, Panel Mounted PCB and Zener Barriers
Features:
- Model 11-8102 is one in a series of intrinsically safe critical speed switch systems that monitor speed and detect motion in all types of machinery and apparatus.
- The11-8102 monitors speed ranges of 60 - 800 RPMs.
- Consisting of a panel-mounted PC Board and Zener Barriers, the I.S. OPTIMA 2 is shipped complete with two non-contacting I.S. proximity sensors that may be remotely located up to one mile from the control unit.
- Ideal for conveyors, crushers, fans, motors and other rotating apparatus.
The EAGLE OPTIMA "First Out" capability enables the user to visually see (by an LED indicator) if the slip switch relay contacts were the first to open. Once the belt is running and the control relay in the OPTIMA unit has energized, the First-Out indication (if activated) will extinguish. If the belt begins to slip and the OPTIMA unit shuts the drive down, the First-Out LED will illuminate. This LED will stay lit until the belt is restarted and the control relay in the Optima has energized. If R1, R2, or R3 would open, this would shut the drive down and also the slip switch contacts would open. But, the First-Out LED would not be illuminated. This would allow the user to see that the slip switch relay contacts were not the first to open and cause the shutdown.
