Outputs

Front Panel LED’s:

  • OK LED: Indicates when the 3500/42 is operating properly.
  • TX/RX LED: Indicates when the 3500/42 is communicating with other modules in the 3500 rack.
  • Bypass LED: Indicates when the 3500/42 is in Bypass Mode.

Buffered Transducer Outputs: The front of each monitor has one coaxial connector for each channel. Each connector is short circuit protected.

Output Impedance: 550 Ω

Transducer Supply Values: -24 Vdc

Recorder: +4 to +20 mA. Values are proportional to monitor full scale. Individual recorder values are provided for each channel. Monitor operation is unaffected by short circuits on recorder outputs.

Voltage Compliance (current output): 0 to +12 Vdc range across load. Load resistance is 0 to 600 Ω.

Resolution: 0.3662 µA per bit

Accuracy: ±0.25 % error at room temperature, -0.66 to +0.70 % error over temperature range, updated rate 100 ms or less.

Signal Conditioning

Specified at +25° C (77° F)

Radial Vibration Frequency Response:
