User Manual 1260-14C
Module Specification 1-3
Specifications
User Connector
Two 50-pin IDC and two 60-pin IDC
Number of I/O Channels
96 Channels
Configuration
I/O lines selected as either input or
output on a pin-per-pin basis
Data Rate
Static to approximately 1 kHz
Operating Modes
Asynchronous
Synchronous
Input/Output
Open Collector
*
All outputs have inductive-load transient suppression diodes built
in, and must be supplied with an external voltage source (V
ext
) for
this protection to be active.
CAUTION
Damage to the driver's output may occur if a highly
inductive load (i.e., relay coil drive) is driven without
an external voltage (V
ext
) being applied to the
module’s drive cells.
V
ext
may differ on a port-by-port basis, or can be jumpered across
all the drivers. The factory setting is to connect each port with its
corresponding V
ext
pin where V
ext
(1-12) are the user's input pins to
the drivers. The outputs may also be internally pulled up if fitted
with DIP resistor packs (this selection is also port- wide).
NOTE
V
ext
is limited to 1A per V
ext
pin used. For example,
the maximum current-carrying capability of a single
V
ext
pin is 1A.
* A CMOS-compatible and LS TTL versions of the 1260-14C are
also available.
