6 Wiring Analog Inputs
6.1. iPro Analog Inputs
The iPro analog inputs are located on the same connector as the
controller power supply. The iPro Case Controller has 10 analog
inputs available, a 5VDC power supply and a 12VDC power 
supply for sensors that require voltage. The 10 inputs are fully 
configurable through the Visograph and may be arranged per the
installation requirements within the input connector. The 
controller has separate input commons depending on the type of
sensor connected. For temperature probes, all commons should be
wired to PbC on Terminal 7. For Voltage output transducers, all
commons should be wired to GND on Terminal 8.
6.2. XEV20D Analog Inputs
The XEV20D analog inputs are located on the same connector as
the controller power supply. The XEV20D has 4 analog inputs
available, a 5VDC power supply and a 12VDC power supply for
transducers that require voltage. Analog input 1 or 2 can be 
resistive type sensors only (NTC/PTC), inputs 3 and 4 can be 
resistive or voltage. However, inputs 3 and 4 must not have a 
resistive sensor and a voltage sensor connected at the same time;
both sensors must be of the same type. The controller has separate
input commons depending on the type of sensor connected. For
temperature probes, all commons should be wired to PbC on 
Terminal 8. For voltage output transducers, all commons should
be wired to GND on Terminal 10.
6.3. IPX106D Analog Inputs
The iPro Case Controller supports the use of the IPX106D 
expansion module. The expansion module has seven (7) analog
inputs, a 5VDC and a 12VDC power supply. All the inputs are 
fully configurable from the Visograph display. If the installation 
requires input/output capacity beyond what the iPro Case 
Controller hardware can handle, then up to two (2) IPX expansion
modules can be added. Like the iPro, the IPX has separate input
commons depending on the type of sensor connected. For 
temperature probes, all commons should be wired to PbC on 
Terminal 14. For voltage output transducers, all commons should
be wired to GND on Terminal 15.
