AX 342 

Process Indicator with 2 Analogue Inputs,  

2 Presets, Relay Outputs and  

Serial RS232 / RS485 Interface 

 

 

 

 
 
 
 

 

Two analogue inputs with independent scaling, each +/- 10V or 0/4 – 20 mA 

 

 

Operating modes for display of input A or input B or the combinations 
[A + B],  [A - B],  [A x B] and  [A : B] 

 

 

Useful supplementary functions like Tare function, programmable averaging 
functions, programmable linearization etc. 

 

 

Aux. output 24 V DC / 100 mA for sensor supply
