MODEL 482A21 LINE POWERED SIGNAL CONDITIONER

 

2

 

1.2 Introduction 

 

Model  482A21  is  a  single-channel,  line-operated  signal  conditioner  for  ICP

®

  transducer  systems.  This  unit  provides 

constant current excitation to the built-in transducer amplifier and decouples the signal from the DC bias voltage.  
 
The unit also contains provision for fault monitoring the channel, as well as provision for externally varying the constant 
current output over a 2 to 20 mA range. This model is factory set at 4 mA. 
 

2.0 Description 

 
Model 482A21 is powered externally by universal power supply model 488B04. The rear panel contains a BNC jack for 
transducer signal INPUT and a BNC jack for signal OUTPUT connections. 
 
The AC signal information is decoupled from the sensor bias by a coupling capacitor and brought out to the OUTPUT 
jack. 
 
The bias monitor located on the front panel consists of a color-coded panel meter that permanently monitors the sensor 
bias level. See sensor specification for correct sensor bias level. 
 

3.0 Installation

 

 
See  the  included  outline  drawing  for  dimensions,  as  well  as  jack  and  control  locations.  Plug  the  five-pin  DIN  output 
connector on 488B04 into the DC INPUT located on the rear panel of 482A21. 
 
Plug the three-wire line cord of the 488B04 into a source of 85 to 264 VAC, 47 to 440 Hz power and switch the power 
on for 482A21. 

 

Pins 3 and 5 are (+) 

Pins 1, 2 and 4 are (-) 

Outside shell is earth/chassis ground

Note: For battery operation use model 488B07 in place of model 488B04. 
 
With no transducer connected to the INPUT connector, the front panel bias indicator meter indicates full scale (yellow), 
which corresponds to open circuit power supply voltage.  See Figure 2.
