CAN Micro Modules
Industrial I/O Modules
These Industrial I/O modules use the PCAN MicroMod
board described below to
provide a ready made data acquisition system. They are available
with a number of the most useful signal conditioning alternatives
plus termination in an industrial case. At 51 x 60 x 20mm, they are suitable for a wide
variety of applications.
Each unit is supplied with a MicroMod board installed on
a signal conditioning motherboard in an all-metal casing. The
electrical connections provide snap-in termination; with a
screw connection as an option.
Status LEDs show power supply and
a single digital output
Speed is settable up to CAN High Speed typically 500k Bits/s and
up to 32 Modules may be put on a CAN network.
Standard supply is push in connectors, screw are available
as an option.
A Peak Interface is required to load the configuration from a PC
into the MicroModules Flash memory but only when the configuration
is changed.
CAN Open compatible firmware is also available at no extra charge for all Industrial
modules.
Five versions are available to suite a range of needs....... |

A flexible, small format, Analog and Digital I/O board with a CAN-Bus interface
that is configurable via CAN without requiring any embedded programming
skills. The Industrial packaged modules above include a case,
baseboard with signal conditioning and a MicroMod
The PCAN-MicroMod board can be plugged into an application to provide
control and monitoring services via the CAN-Bus. It provides the following
- 8 analog inputs, 10-bits resolution, Vref 5 V
- 8 digital inputs
- 8 digital outputs
- 4 PWM / frequency outputs, with a range 1 Hz-20 kHz
- Dimensions 32 mm x 36 mm
- Only requires 5V regulated supply
- Configurable via Windows PC software
- Controller is Fujitsu MB90-F497 which can be user programmed if
required.
|
 |
The integrated firmware provides simple configuration of the target
system via a Windows utility program, the configuration data being sent to
the module via CAN. No embedded programming skills are required to set up a
system. Up to 32 PCAN-MicroMod boards can be
put onto a single CAN
network.
The Windows software provides the user with the following
board configuration options :
- The Digital Input values can be transmitted over the CAN-bus by the
board;
on demand, periodically or
following a signal level transition (rising edge, falling edge or
both transitions).
- Digital Inputs can be logically connected
(AND, OR, XOR, NAND, NOR, XNOR, time delayed) with the results being sent to
the desired Digital Output and/or transmitted over the CAN bus.
- Digital Outputs bits may be set via the CAN-bus.
- Analog Values can be scaled, have an offset added or be set via a characteristic
curve and the result transmitted via the CAN-bus.
- Analog Values can have a hysteresis control applied to their
output.
- Up to four pairs of Digital Inputs can be treated as standard
automotive rotary-encoders with absolute or differential position
being reported over the CAN-bus.
- Requires a PEAK CAN interface to allow configuration
If required the firmware integrated on the board can be
replaced with user designed software, a suitable C Compiler is
available at no cost from the micro-controller manufacturer.

An optional
evaluation board simplifies development of user designed
carrier boards and also makes the MicroMod an ideal CAN evaluation
tool.
- < note does not include the MicroMod CPU board >
- Protected digital inputs with LEDs
- Open-Collector output drivers for the digital outputs and CMOS PWM
outputs.
- Potentiometers for the analog inputs (Can be switched off via
jumpers), low pass + resistive voltage divider for voltages > 5
V
- Serial interface for Flash download or for user implementation
- Optional low-speed CAN transceiver
- Dimensions: approx. 100*100 mm˛
