Product description
IQAN-XC21
The IQAN-XC21 is a stackable, flexible expansion module designed as a signal input
module for use in cab, using 12/24 Vdc power supply.
Two IQAN-XC21 modules
I/O overview
Voltage inputs
The IQAN-XC21 module has eight (8)
voltage inputs
VIN-A thru VIN-H for
connection of 0-5 Vdc signals. The inputs are multi-purpose and may be configured as
digital inputs
DIN-M thru DIN-T.
Voltage inputs
and
digital inputs
share positions, see
below.
Digital inputs and outputs
The XC21 module has twelve (12)
digital inputs
DIN-A thru DIN-L for connection of
on/off signals. Most of these inputs are multi purpose and can be configured in other
ways.
The eight (8)
digital inputs
DIN-A thru DIN-H can configured as
low-side digital
outputs
DOUT-A thru DOUT-H.
The ten (10) inputs DIN-J, DIN-K and DIN-A thru DIN-H can be configured as
f
requency inputs
FIN-A thru FIN-J or
pulse count inputs
PCNT-A thru PCNT-J.
The three (3) inputs DIN-A thru DIN-C can be configured as
pulse width modulation
inputs
PWMIN-A thru PWMIN-C.
The two (2) inputs DIN-K and DIN-L can be configured as
quadrature input
for
measuring directional frequency input DFIN-A or directional pulse count DPCNT-A.
Digital inputs, digital outputs, frequency inputs, pulse count inputs, pulse width
modulation inputs
and
quadrature inputs
share positions, see below.
(8) Voltage inputs VIN-A, VIN-B, VIN-C.....VIN-H
or
(8) Digital inputs DIN-M, DIN-N.....DIN-T use positions VIN-A thru VIN-H
(12) digital inputs DIN-A thru DIN-L
or
(4) digital inputs DIN-I thru DIN-L and (8) low-side digital outputs DOUT-A thru
DOUT-H (use positions DIN-A thru DIN-H)
