1.1 Features and Applications
The PB1651PWM1 Module is used to generate and measure PWM and digital
signals. It can be used both with the ES1651 Carrier Board (VMEbus) and with
the ES4350 Carrier Board (VXIbus).
The PB1651PWM1 Module has 24 input channels and 16 output channels
which can all be configured as PWM or digital I/O channels.

2 Hardware Features
This section contains a description of the inputs and outputs of the
PB1651PWM1 Module.
2.1 Outputs
Each of the 16 outputs can be configured either as a TTL, UBatt or Open
Collector output. Each channel has two ”high-side” drivers and one
”low-side” driver (see Fig. 2-1 on page 8).
The outputs have a resolution of 0.02% in the range 0 to 10 kHz and 0.2% in
the range 0 to 100 kHz. The maximum output current per channel is 100 mA
– the outputs are protected against overvoltage to +60 V.
The output voltage level is determined by two external supply voltages to be
specified.
The following figure shows the block diagram of the outputs.

Hardware Features 9
2.2 Inputs
There are the following measuring modes for the 24 measuring inputs:
• Pulse width measuring
• Additive pulse width measuring
• Pulse and edge counting
• Frequency and cycle time measuring
• Duty cycle measuring
• Level measuring
These measuring procedures are described in the Real-Time Execution
Connector V1.5 User’s Guide.
The input voltages refer to two external reference voltages which are supplied
via the front-facing connector. The threshold voltage for edge detection is
In_Ref_1/2 * 0.5.
The inputs have overvoltage protection to +60 V.
The following figure shows the block diagram of the inputs.

2.3 Configuration
Signal output is configured and controlled by the Real-Time Execution
Connector and LABCAR-OPERATOR. A hardware configuration of the module
is not necessary.
2.4 LEDs
There are 3 LEDs on the front panel of the PB1651PWM1 Module, the
meaning of which is described below.
Fig. 2-3 LEDs on the Front Panel
The LEDs of the PB1651PWM1 Module have the following significance.
Driving the ”CH” LED
The driving source of the ”CH” LED can be configured in the software – one
of the 24 input channels or ”RTIO” can be set as the control source.
If an input channel is set as the driving source, the LED lights up when the
channel level is high and does not light up when the channel level is low. If
”RTIO” is set as the driving source, the LED can be powered on/off by the
simulation model.
The ”LED Driving Source” parameter is described in the Real-Time Execution
Connector V1.5 User’s Guide.
Display of the Version Number of the I/O Modules
When the signal box is powered on, the I/O modules show the version number
via the ”RD” and ”CH” LEDs. The version number consists of three parts (e.g.
2.1.3). First of all, the ”RD” LED flashes twice (”CH” LED off). Then the ”RD”
LED flashes once (”CH” LED lights up). Then the ”RD” LED flashes three times
(”CH” LED off).
LED Color Meaning
ER Red Error
RD Green Ready
CH Green Can be configured using the software (see the
section ”Driving the ”CH” LED” later in this chapter)
Tab. 2-1 Significance of the LEDs
RDER CH

Hardware Features 11
After the version number of the relevant I/O module has been displayed, the
two LEDs, ”RD” and ”CH”, go out and take on the relevant function of the I/O
module used.

Pin Assignment12
3PinAssignment
This section describes the pin assignment of the PB1651PWM1 Module.
The connector for the signal outputs is a DSub62HD connector (female). The
shielding is at front panel and housing potential and thus at protective earth.
