Module Inputs
The XM-124 module accepts eddy current transducer signals, accelerometer
signals, and voltage signals from dynamic measurement sensors such as those
from velocity or pressure transducers. A tachometer input is also provided.
Module Outputs The XM-124 module provides an active buffer for each of the vibration
transducer inputs. The module also provides a resistive buffer for the
tachometer input, and two isolated, analog 4…20 mA outputs independently
programmed to represent any measured parameter for the two transducer
inputs.
The two 4…20 mA outputs are independently programmed to represent any
measured parameter from either channel. Isolation is 250V between channels
and to other circuits.
