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.

 

Versions are available to suite a range of needs.......

PCAN-MicroMod board

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.

 

CAN Micro Module

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.
