Solid
State I/O Modules and A24A Mounting Card
FEATURES
FUNCTIONAL
DESCRIPTION
The
solid-state relay I/O modules are used as power control and
voltage monitoring interfaces between high level DC or AC
lines and TTL logic levels. The modules are in a slim, space-saving
form. Four functions are offered: DC Input, DC Output, AC
Input, and AC Output.
The
A24A can hold up to 24 modules. Field-side terminations are
provided via convenient terminal strips with points isolated
from each other. The logic side has a common logic supply
bus with screw terminals for input power connections. Logic-side
connections are via a 50-conductor edge connector.
APPLICATION
GUIDE
Any
of Chassis Plans' buffered digital I/O cards (IOD-24, IOD-48S, IOD-72,
or IOD-120) may be used and one 24-bit port will be used per
A24A. Various combinations of I/O modules can be intermixed
on one A24A mounting card. However, each contiguous group
of eight channels must contain only input or output modules.
If more than 24 I/O modules are required, additional 24-bit
ports may be necessary.
In
some cases, logic power required can exceed the current handling
capability of digital I/O cards. For these instances, an external
5 VDC power supply is recommended. Screw terminals are provided
on the card for those power supply connections in addition
to a jumper next to the terminal strips that should be cut.
