Signal input module input ranges
(continued)
Table 4-1:
Attenuator Gain Input Range +/-
/1 x1 5.0 V, 50 g, 50 ips, 25 mil
/2 x10 1.0 V, 10 g, 50 ips, 5 mil
/1 x10 0.5 V, 5 g, 5 ips, 2.5 mil
The integrator allows acceleration signals to be converted to velocity.
The 6510 Signal Input module selects 2 of the 12 vibration channels at a time and routes
them to the Processor module for spectral analysis. RMS-to-DC conversion is performed on
all 12 channels. The RMS and DC signals are routed to the Processor module for Gross Scan
collection.
The Transient Filter Board is required for Transient data acquisition.
To measure 4-20 mA signals, add a resistor across the channel input. A typical value is 250
ohms, which converts 4-20 mA to 1-5 V. Maximum series resistor value is 1000 ohms.
4.8.2 Tachometer inputs
The Tachometer inputs allow measurement of two pulse tachometer sources per module.
Tachometer sensor types may include, but are not limited to: eddy current sensor, Hall
effect sensor, or TTL pulse type from various sources.
The Tachometer Input module features either fixed voltage trigger or “adaptive”
automatic triggering. Triggering parameters may be set independently for each
tachometer sensor input.
An input gain selection of x1 or x5 may be selected for each channel. A gain of x5 is
recommended for tachometer inputs smaller than 1 V pk-pk. If the x5 input gain is used,
care should be taken to make sure that the input signal remains /-24 V, including
any sensor bias or gap voltage.
4.8.3 I/O relay channels
Each 6510 Signal Input module has two I/O relay channels that provide optically isolated
discrete inputs or dry contact outputs. Inputs can be between 5 V and 24 VDC. Outputs are
limited to 24 VDC @ 0.5 A.
Note
AC relays are not provided.
