Product Overview
1-2 Series 505 Analog I/O Modules User Manual
1.1 Description
The Series 505 Analog Input (PPX:505–6108A and PPX:505–6108B), and
Output (PPX:505–6208A and PPX:505–6208B) Modules are single-wide
versions of the Analog I/O Modules (PPX:505–6108 and PPX:505–6208), and
can replace the double-wide models without any wiring changes. The Input
Modules (PPX:505–6108A and PPX:505–6108B) offer the additional benefit
of an optional ± 10 V input range, and they do not require external
user -supplied power . The Output Modules (PPX:505–6208A, and
PPX:505–6208B), like the double-wide PPX:505–6208, require user -supplied
24 VDC power to maintain low power consumption from the base.
The Series 505 Analog I/O Modules (Figure 1-1) connect the controller with
devices which monitor or control pressure, position, flow , temperature, or
speed using voltage or current signals. The input module translates an
analog input signal from a monitoring device into an equivalent digital word
and transmits that data to the controller for processing. The output module
translates a digital word from the controller into an equivalent analog
signal and transmits that data to an output device that controls pressure,
position, flow , temperature, or speed.
A Module Good LED on the front of each module indicates the status of the
power , self-diagnostics, and the fuse (for the output module). Figure 1-1
shows the location of the Module Good LED indicator of the PPX:505–6108B
and PPX:505–6208B.
If the LED is on:
• System and user power are good
• Fuse is good
• Module has passed self-diagnostics
If the LED is off, one of the above has failed. See Chapter 3 for instructions
on using the LED to troubleshoot.

Product Overview
1-4 Series 505 Analog I/O Modules User Manual
1.2 Analog Input Operation
The Analog Input module operates asynchronously with the controller . That
is, the controller and module do not update at the same time. Instead, the
module translates all analog inputs in one module update and stores the
translated words in buffer memory . When the controller I/O scan starts, it
retrieves the words from the buffer memory of the module.
The PPX:505–6108A analog signal is translated into a 12-bit digital word.
Since the controller requires a 16-bit word for inputs, the 12-bit value from
the converter is placed into a 16-bit word for transmittal to the controller .
As shown in Figure 1-2, of the four bits not used for the converter
magnitude, one is used to show the sign of the value, one is used to note
overrange values, and the remaining two are not used and are set to zero.

The PPX:505–6108B analog signal is translated into a 13-bit digital word.
Since the controller requires a 16-bit word for inputs, the 13-bit value from
the converter is placed into a 16-bit word for transmittal to the controller .
As shown in Figure 1-3, of the three bits not used for the converter
magnitude, one is used to show the sign of the value, one is used to note
overrange values, and the remaining one is not used and is set to zero.

An overrange condition arises from an excessive voltage input, causing the
digital word to be in excess of ±32000. Figure 1-4 shows the effects of
excessive voltage. V alues in parentheses apply to the ± 10 V range.

The analog input module has eight inputs. You can select each of the eight
inputs to receive either voltage or current as the incoming analog signal.
Since the inputs are single-ended, the source for a current signal must be a
true current-sourcing transmitter, not a current-sinking transmitter .
• For a voltage input, the incoming signal may range from –5 to +5 V , or
from –10 to +10 V. The optional voltage input range of ± 10 V is available
via jumper selection on the circuit board. The voltage range selected
applies to all eight input channels. Refer to Figure 3-2.
• For a current input, the incoming signal may range from 0 to 20 mA.
NOTE: The module is factory-calibrated and shipped configured for the ± 5 V
input range, which is required for current input using the internal sense
resistors. If your application requires ± 10 V , recalibrate the module with the
± 10 V setting selected.
The input module has eight (one per point) built-in, precision resistors
(250 Ω , 0.1%). The resistor changes input current to voltage, which is what
the module monitors internally . The built-in resistor allows a current range
from 0 to 20 mA. You may use other external resistor values for other
current ranges. If you install an external resistor
, be sure that it meets the
± 5 V input constraint and connects between V oltage In and Return for the
selected channel. Follow proper safety guidelines when you install resistors.

The PPX:505–6108A module has a resolution of 8 counts out of 32000. That
is, the smallest unit into which the module divides a unipolar input is 1 part
out of 4000. For a voltage input of 0 to +5 V , this division corresponds to a
step of 1.25 mV . For a current input of 0 to 20 mA, a step of 5 µ A can be
resolved.
Use the following equations to calculate the digital word which results from
a particular voltage or current input.

1.3 Analog Output Operation
The analog output module operates synchronously with the controller . Any
change in the output signal is dependent on the update time of the module.
Figure 1-5 shows this relationship.

The analog output module has eight channels, providing simultaneous
voltage and current, ranging from 0 to 10 V and from 0 to 20 mA. Note that
the current output is a sourcing type. Therefore, any shorts in the output
circuit cause the output current to bypass the field device in the circuit.
The controller sends a 16-bit binary word to the module. Figure 1-6 shows
the data word format. The digital value, which is translated into an analog
output signal, occupies 12 of the 16 bits. The most significant bit (MSB)
denotes the sign of a value. The remaining bits are unused.

The resolution of the module is 8 counts out of 32000, regardless of whether
the signal is used as voltage or current. Therefore, the smallest step unit for
voltage is 2.5 mV and for current is 5 µ A. To calculate the digital word
necessary to achieve a certain output voltage or current, use the following
equations.
