EXPANSION MODULE
16
digital IN +
8 digital OUT
high-speed
photo-coupled
ISA BUS
|
|
|
-
I/O expansion
module,
suitable for Leomatic ISA cards (i.e.: P48).
It supports 16 digital inputs + 8 digital outputs, high-speed,
photo-coupled.
-
These I/O are
"high-speed" because they are directly handled by the DSP
processor of the hosting card (typical response time 100
µs), regardless of the main CPU loop
time.
-
These I/O are
photo-coupled (galvanic insulation of the field-ground and the
logic-ground), so insuring the maximum protection from
electrical noises or
accidental damages.
-
Output sections use
solid-state components,
granting protection against short-circuits, over-temperatures,
overloads, inversions of filed-power polarities.

Functions
|
- 16
digital photo-coupled inputs, PNP type
(24 Vdc nominal)
- 8 digital
photo-coupled outputs, PNP type
(24 Vdc nominal)
- 1 pin may be used as
input or as output, so you have 16+7 or 15+8
physical I/O
- Each output acts as
"current source", with a maximum fan-out of 500 mA.
|
- The functions of P49
expansion module are already included in the SW
library of the hosting card.
