PMDX announces 3 new I/O accessory boards

PMDX is now shipping 3 new accessory boards to add
additional isolated I/O to systems using parallel
port or SmoothStepper interfaces.


PMDX-108-Input

The PMDX-108-Input provides 8 isolated inputs to
work with the 8 data bits of a secondary parallel
port or Port 2 of a Smoothstepper. It can be used
with the PMDX-125 to provide complete access to
all signals on the secondary port or can be used
with any system for access to just the 8 data bits.
Isolated power is generated by an on board inverter.
The inputs accept contact closures, NPN sensors,
3.3 or 5 volt logic signals, and other signals up
to 24 volts, such as PLC interfaces.


PMDX-108-Output

The PMDX-108-Output provides 8 isolated low current
solid state MOSFET relays driven by the 8 data bits
of a secondary parallel port. Like the PMDX-108-Input,
it can be used with the PMDX-125 and SmoothStepper.
The outputs can interface with VFD's, PLC's and
other devices that accept contact closures as inputs.
The outputs can also be used to drive other medium
power relays with AC or DC coils up to 150 volts.
Each relay output is isolated from the computer and
from the other outputs.


PMDX-104

The PMDX-104 provides 4 mechanical relays rated at
5 amperes for controlling miscellanious machine
functions. The PMDX-104 accepts logic signals from
any source via terminal strip inputs. It is ideal
for use with the 4 control bit outputs of a parallel
port presented as logic signals by many breakout
boards including the PMDX-122 and PMDX-125. Terminal
layout and power requirements are designed for very
easy interconnection to a PMDX-125.

When used with the PMDX-125 these boards obtain
their operating power from the PMDX-125 and do not
require any additional power source.

These products are now shipping from stock and the
user manuals are available from the PMDX web site.
