Bacharach GDX-150 Manual Do Proprietário

 

Installation Instruction 5600-9000 

Rev. 2 – February 2011

 

 

 

These instructions describe how to wire the GDX-150 
transmitter to a Bacharach GDA-400 or GDA-1600 
controller. 

The GDX-150 is a sensor transmitter that provides a 
4-20 mA output signal based on the concentration of gas 
detected. The 4-20 mA interface is convenient for use 
with Bacharach’s GDA-400 and GDA-1600 controllers 
as well as other devices. 

Please review the GDA-400 manual (5700-9000) or the 
GDA-1600 manual (5700-9001) for a more detailed 
description of its 4-20 mA interface and for instructions 
on properly configuring the controller.  

 

  GDX-150 transmitter  

  GDA-400 or GDA-1600 controller with 4-20 mA input(s)  

1.  The GDX-150 has three wires exiting the rear of the housing (one green, two white). These wires 

should be connected to one channel of the controller’s 4-20 mA input module (5700-0014 for 
GDA-400; 5700-0006 for GDA-1600). The green wire is the ground wire and should be connected 
to the common terminal.  

2.  The white wires provide power to the transmitter and the 4-20 mA signal to the controller.  

Connect one of the wires to the power terminal and the other to the signal terminal.  

NOTE: The polarity of the two white wires is irrelevant.  

3.  Once all connections are made refer to the controller’s user manual for properly configuring the 

GDX-150 to operate with the controller.
