Analog I/O Module
The main functions of the analog I/O module are as follows:
- 
                  
                  
Monitor voltage or current from analog sensors (such as thermocouple, PT100, PT1000, NI100, NI1000, PTC Binary) via two −10 to +10 V /
0 to 20 mAcapable inputs - 
                  
                  
Control voltage-driven actuators (such as variable speed drives or a current loop to the controller’s analog input) via one −10 to +10 V / 0 to 20 mA capable output
 - 
                  
                  
Capture statistical operational data:
- 
                        
                        
Number of power cycles
 - 
                        
                        
Number of device events
 - 
                        
                        
Time the module is on
 
 - 
                        
                        
 
The reference number is TPRAN2X1.
The analog I/O module is connected:
- 
                  
                  
Upstream to the 24 Vdc source needed to power the downstream actuators
 - 
                  
                  
Input channel: downstream to an analog sensor or sensor transmitter
 - 
                  
                  
Output channel: downstream to the control input of a voltage-driven actuator, such as a variable speed drive
 
Refer to Avatar Wiring Schematics for module wiring.
Devices connected to the analog I/O module must be protected against short circuits by external means like fuses.
The analog I/O module communicates with the bus coupler, sending operational data and receiving commands.
