Powerlite-MC28AD: ($81USD) Powerlite-MC28AD-16: ($105USD)
Unlike other products on
the market, PicBlocks are high quality pre-assembled pcbs. Ideal
for development of software, they are also designed to be included in systems
as a finished product.With on-board power supply, input and output buffering
and quality connectors, they are ideal compact replacements for PLC's in
process control situations.
The MC18D: 
Has a turned pin socket for an 18 pin PIC
or SCENIX micro-controller
High quality construction PTH
and ground planed
Flexible
and versatile
Ideal
for development
Ideal
for education
Replacement
for PLCs
PIC
or SCENIX Compatible
 Has a turned pin socket
for an 28 pin PIC or SCENIX micro-controller.
Provides 8 buffered and
filtered PortB inputs to cope with a range of input voltages and noisy
environments.PortA is unfiltered or buffered allowing selection of digital
or analogue inputs or digital outputs
Has 8 open collector digital
outputs driven by PortC which can sink a maximum of 500ma each
Power can be either AC or
DC and both the rectified DC and the regulated 5V supply are available
for driving external circuits
An on-board reset button
is provided as is space for output pull-up resistors should they be required.

 The
MC28AD-16 is the latest addition to the PicBlock range and gives the user
an unprecedented 32 I/O from a 28 pin pic
chip.
By
utilising a pair of UCN5841 8-bit serial input latched drivers, 16 digital
500mA* open collector outputs are provided on J2
using
only 4 of the pic chips I/O lines.
Optional
SIL resistor arrays can be added as pull-ups.Jumpers** alow these to be
connected to either the on-board +5V or the
pre-regulated
applied voltage.
PortA***,
PortB and RCO, RC1 and RC2 are all available directly on J1.
An
In Circuit Serial Programming header is provided as is a 9-way RS232 connector
for either serial comms or ootloading.
An
incoming reset line is included on the RS232 connector as is an on-board
reset button.
The
board includes a 7805 regulator and can be powered by up to 24V DC.The
on-board 5V is available on J3 for powering
external
circuits.
If
preferred, an on-board link can be removed and the board powered by an
existing external regulated 5V DC.

Allegro UCN5841 datasheet available from our website
**Each
UCN5841 pull-up selection is independent
***Except
PortA.4
