Show APPENDIX C SPECIFICATIONS OF FM/FM TONE TELEMETRY CONTROLLER 1. 2. Control Station Command Signals Six distinct commands can be generated by a push button. Generator Monitor Outputs Seven outputs are displayed for several seconds each, in sequences each time that the interrogate command is initiated. Automatic Interrogation A timer permits automatic interrogation of the monitored outputs at any interval between 2 and 10 minutes (other time intervals are available). Magnetic Tape Recorder Output A rear panel output is provided for interfacing of the 3KHz 7. 5% signal. Radio A 417 MHz FM transmitter/ receiver is installed in the control panel of the station. It has a minimum modulation frequency response of 300 to 3000 Hz, and an RF power output of 2 watts. It is connected to a gained directional antenna. Power 115 VAC, 60 Hz Generator Station Command Signals Five multiple relay contact closures, rated at 1 amp at 115 VAC or 32 VDC. Closures are activated whenever the respective command is generated at the control station. Generator Monitor Inputs Seven inputs are available for telemetering the outputs of various generator sensors~ Sensitivity is 0-100 mv with an input impedance of greater than 100 KO. 355 |
