RTD, T/C, Ohms, mV, Volt, mA.    

See Table 38 for PV Input types and ranges. 

10 megohms for T/C and mV inputs; > 1 megohm for volts and 250 ohms for 
mA inputs 

8 per module  

Photo-MOSFET Relay  

400 Vdc point-to-point, solid state switching; 1k Vdc to logic 

RTDs are isolated in pairs (I

RTD

 is common to two inputs.) 

Series mode > 60dB 

Common mode > 130 dB at 120 Vac 

T/C, mV, V (except for following ranges) are configurable for Upscale, 
Downscale, Defined Value, or None:  

Volt: -500 mV to 500 mV; -1 V to 1 V; -2 V to 2 V; -5 V to 5 V; 0 V to 10 V; -10 

V to 10 V; inherent to zero volt 

RTD: Inherent Upscale 

MA: Inherent Downscale 

Via current pulse 

If greater than 100 ohms, a warning status is provided as an output for the AI 
block
