IQAN-MC3
3 Product description
Instruction book, IQAN-MC3
Inputs
All of the 32 inputs on the IQAN-MC3 can be used for safety related signals, when the
inputs are configured in pairs.
On the unit there are 16 analog inputs for 0-5 V signals from e.g. hall-effect or
potentiometer sensors; 8 digital inputs for e.g. switches; and 8 frequency inputs for e.g.
reading signals from quadrature encoders, see list.
Proportional outputs
All of the outputs on the IQAN-MC3 can be used for safety related signals.
There are 4 double proportional current outputs , designed to drive proportional
hydraulic valves. These outputs can control 4 bi-directional valve sections or 4 single
solenoid devices (ie. proportional cartridge valves), see below.
In order to increase the performance of the proportional outputs when controlling
proportional valves, the
dither frequency can be adjusted.
Digital outputs
All of the outputs on the IQAN-MC3 can be used for safety related signals.
There are 5 digital outputs , for driving on-off solenoids. Two of these are also intended
to function as alarm outputs, for e.g. LED lamps, see below.
CAN related functions
The IQAN-MC3 uses a CAN-bus (CAN = Controller Area Network) to communicate
with IQAN expansion modules and other systems. The CAN-bus is a robust
communication protocol that is widely used and well proven within the automotive
industry.
The unit has 4 CAN buses, CAN-A thru CAN-D. The buses may be configured using
IQAN software to be ICP (ICP = IQAN CAN Protocol), SAE J1939 or Generic user
defined CAN protocol (e.g. CANopen).
Communication
The communication interfaces are used for uploading/downloading applications or
diagnostics when connected to a computer. It is recommended to reserve one of the
CAN buses for communication and diagnostics. A CAN communication card is
required to be installed in your PC to use this feature. Please contact Parker for a list of
CAN cards that are currently supported.
