General
Description
The universal input module supports current, voltage, RTD, resistance, thermocouple and
millivolt type inputs. The module digitally converts and stores analog data from any
combination mentioned above. Each input channel is individually configured via
software for a specific input device, data format, filter frequency, and provides open-
circuit, over-range, under-range detection and indication.
!
Attention
The IF8u module supports up to 8 channels of voltage, current or
thermocouple or up to 4 channels of RTD/resistance. Each
RTD/resistance input requires two channels. Refer to the table below
for possible combinations.
Table 1-1 (Channel Configurations)
8 channels Voltage/Current/Thermocouple + 0 channels RTD/Resistance
6 channels Voltage/Current/Thermocouple + 1 channels RTD/Resistance
4 channels Voltage/Current/Thermocouple + 2 channels RTD/Resistance
2 channels Voltage/Current/Thermocouple + 3 channels RTD/Resistance
0 channels Voltage/Current/Thermocouple + 4 channels RTD/Resistance
