TDR-L: Pulse Relay Frequency Relay

• 24 to 240VAC/VDC

  (Universal Voltage)


• PNP or NPN Input


• Pulse Frequencies


• Adjustment Knobs


• Plug-In Package


• DPDT Contacts


• Status LEDs


The TDR-L can be used to monitor the frequency of pulse from a proximity sensor or a contact closure. The TDR-L will supply the power the prox.


When supply voltage is available, the cycling of the prox output or contact closure within the adjustable frequency ranges will allow the output contacts of the TDR-L to energize when the frequency is above the set point and de-energized when the frequency is below the set point.


There are adjustable time delays available for pick-up and drop-out.


One LED will flash at the frequency of the pulse inputs (faster frequency may simply appear On). The other LED will be red when the output relay is de-energized, green when the output relay is energied and flash during pick-up and drop-out timing.
