The Fre­quency Mon­i­tor is used to switch loads on/off when the input sig­nal fre­quency ex­ceeds/drops below a de­fined thresh­old fre­quency.

Function

The fre­quency mon­i­tor mea­sures the input sig­nal fre­quency ap­plied to ter­mi­nal 15 and en­er­gizes/de-en­er­gizes the out­put when the sig­nal fre­quency ex­ceeds/drops below the de­fined thresh­old fre­quency. The thresh­old fre­quency can be se­lected from the 10 - 1.000 Hz fre­quency range. In ad­di­tion, com­bi­na­tions in­clud­ing cus­tom delay times are pos­si­ble.

Please refer to the chap­ter hous­ing and base plates for ad­di­tional hous­ing op­tions.
