IQAN-MC31
3 Product description
Instruction book, IQAN-MC31
Voltage Inputs
The IQAN-MC31 module has sixteen (16)
voltage inputs
VIN-A thru VIN-P for
connection of 0-5 Vdc signals.
Digital Inputs
The IQAN-MC31 module also has sixteen (16)
on/off inputs
DIN-A thru DIN-P for
switches. The inputs are multi-purpose and for flexibility may be configured in other
ways. The input pins DIN-A thru DIN-H can be configured as
frequency inputs
for
measuring frequency.
On/off inputs
and
frequency inputs
share positions, see list.
Proportional outputs
The MC31 module has four (4) double
proportional outputs
for controlling
proportional valves. These outputs can control four bi-directional valve sections or four
single solenoid devices (ie. proportional cartridge valves). The proportional outputs can
be used in two different modes. Either
Current mode
(current closed loop) or
PWM
mode
(voltage open loop) signals can be selected and the parameters configured using
IQAN software. See below.
In order to increase the performance of the proportional outputs when controlling
proportional valves, the
dither frequency
can be adjusted.
Digital outputs
The MC31 module has ten (10) digital outputs for driving on-off solenoids. There are
five (5) high side outputs and five (5) low side outputs. See below.
These outputs can be combined to provide five (5) diagnostic capable configurations.
See below.
(16) Voltage inputs VIN-A thru VIN-P
(16) Digital inputs DIN-A thru DIN-P
or
(8) Frequency inputs FIN-A thru FIN-H use positions DIN-A thru DIN-H.
and
(8) Digital inputs DIN-I thru DIN-P.
(4) double proportional outputs COUT-A thru COUT-D
or
(4) double proportional outputs PWMOUT-A thru PWMOUT-D
(5) High side digital outputs DOUT-F thru DOUT-J
and
(5) Low side digital outputs DOUT-K thru DOUT-O
(5) Diagnostic digital outputs DOUT-A (HS + LS) thru DOUT-E (HS + LS)
