4.4 Analog IO Configuration
The EPC module provides four Analog Inputs, two Analog Outputs and a Current Driver: Analog Inputs
1, 2 and 3 are referred to as General Purpose Analog Inputs and have a maximum input range of -
10VDC to +10VDC. Analog Input 4 is usually referred to as LVDT Input. This input is intended for
sinusoidal LVDT input. Analog Outputs 1 and 2 are programmable with a range of -10VDC to
+10VDC. The Current Driver is either a Linear or PWM signal to drive a valve.

Table 12: General Purpose Analog Input Configuration
Program items 850 through 853 are used to configure Analog Input 1, program items 860 through
863 are used to configure Analog Input 2 and program items 880 through 883 are used to configure
Analog Input 3. The Analog Inputs are configured from the Analog Input Configuration Form (select
menu Diagnostics and then Analog IO Configuration).
Offset
: A voltage offset can be applied to the Analog Input. The voltage offset can be in the range of
-10VDC to +10VDC at 0.1VDC increments. The Analog IO Configuration Form allows for the
direct entry of a voltage offset.
