Analogue Input Wiring
Each analog input channel is individually isolated from each other and from other electronics (CPU, Local us and etc.). Current or
voltage mode is selected for each channel individually by setting or removing dedicated jumpers on the boards. The jumpers are
located on the I/O board, beside the output of each channel (for AI0-AI4), and also on the extended board, if available (in 42IO version
for extended AIs). For each channel, the related jumper should be set for current mode, or should be removed for voltage mode.
Figure 11: Current/Voltage mode selection jumpers (for AI0-AI3)
Figure 12: Current/Voltage mode selection jumpers in extended board (for extended AIs)
For each channel in each mode, the values for input range and filter are configured through web-based configurator and/or WorkSuite
configuration (details are provided in RTU User Guides).

Extended IOs Wiring
Type of these I/Os are not fixed and could be varied according to the I/O card (I/O plug-in expansion card) version.
For 42IO version, the type of these I/Os are 8 channels configurable digital inputs/outputs on section E, and 2 channels analog inputs
plus 4 channels fast digital / 32-bit counter inputs on section F.
Each channel of Configurable digital I/Os can be configured as digital input or digital output through web-based configurator and/or
WorkSuite configuration (details are provided in RTU User Guides).
Figure 14: Expanded IOs
For 42IO version, pin assignment of the expanded I/Os (on section E and section F connectors) are described in the following tables:
Expanded IOs / Section E
Expanded IOs / Section F
Pin Name Description
Pin Name Description
1 - (or C) Negative power supply (or common)
1 AI4+ Analog input channel 4, positive input
2 DIO0 Configurable digital I/O channel 0
2 AI4- Analog input channel 4, negative input
3 DIO1 Configurable digital I/O channel 1
3 AI5+ Analog input channel 5, positive input
4 DIO2 Configurable digital I/O channel 2
4 AI5- Analog input channel 5, negative input
5 DIO3 Configurable digital I/O channel 3
5 Com0,1 Common for digital/counter input channels 0 & 1
6 DIO4 Configurable digital I/O channel 4
6 CI0 Digital/counter input channel 0
7 DIO5 Configurable digital I/O channel 5
7 CI1 Digital/counter input channel 1
8 DIO6 Configurable digital I/O channel 6
8 CI2 Digital/counter input channel 2
9 DIO7 Configurable digital I/O channel 7
9 CI3 Digital/counter input channel 3
10 + Positive power supply
10 Com2,3 Common for digital/counter input channels 2 & 3
Characteristics and wiring diagrams for all digital and analog I/O channels of the expanded IOs are the same as the other I/Os described
before. Digital/counter inputs group 1 (CI0 and CI1) and digital/counter inputs group 2 (CI2 and CI3) are electrically isolated from each
other (equipped with optocouplers with separated commons for each group).
Note 1: Common or negative pin of Configurable digital I/Os on section E of expanded IOs ( - or C ) is NOT internally connected to the
common or minus of the other sections.
Note 2: Commons for Digital/counter input channels ( Com0,1 and Com2,3 ) are NOT internally connected. It means that they must be
connected to “minus” separately. In other words, if COM0,1 is connected to the minus and COM2,3 is not connected, only CI0 and CI1
will work according to their applied signals, and CI2 and CI3 will not work.

8. Display and Keys
On the RTU32S front panel, there are a LCD display and 4 keys. Important statuses of the RTU32S, including statuses of communication
buses and I/O ports are shown on the LCD display. The displayed parameter on the LCD can be changed by the keys.
Figure 18: Display and Keys on the RTU32S Front Panel
After power up, the backlight of the LCD is ON and all parameters are shown sequentially, in this way that a parameter is shown for
about one second and then it changes to another parameter, and it will continue in the same way. In this mode, only “Enter” key is
worked and the other keys are not functional. y pressing “Enter”, the parameter which is showed on the LCD is fixed to display and is
not changed to another parameter. In this mode, the displayed parameter can be changed by “Up” and “Down” keys. Also, by pressing
“Esc” key, the LCD returns to the primary mode which displays all parameters sequentially.
When the backlight of the LCD goes ON, it will be turned down automatically after one minute if no key has been pressed. When the
backlight is OFF, it will be turned on by hitting each key.
In the following pictures, some examples of displayed values and statuses on the LCD display are illustrated.
