An alarm-board is available on request. The pulse is like a rectangular wave, the frequency correlates to 2 x rotor speed. At blocked rotor the output signal could be L {<□ ,4V) or H (5V). IMPORTANT: The pulse output is no! protected against short circuit and must not connect to gnd or Vcc without pre-resistor. A pull-up-resistor is needed. Do not connect not used pulse output (insulate). | | | | | | | | | | • ACCESSORIES: | | | | | | | | | | CONNECTOR: on request | | | | | | | | | | • ORDER INFORMATION: MFB40H05 SEPA" Miniature fan, 40x40x10mm, MFB40H05L SEPA' Miniature fan, 40x40x10mm, MFB40HQ5A SEPA" Miniature fan, 40x40x10mm, MFB40H05LASEPA" Miniature fan, 40x40x10mm, | | | | | | 5VDC, ball bearings, pulse.
