Din Rail I/O Modules
The Power-IO modules lead the
industry in cost effective, small size, industrially hardened i/o units. With a
width of just 0.30 inches (7.5 mm), the i/o modules represent the smallest,
discrete input/output modules for the majority of industrial, laboratory, or
automation requirements. All modules provide 4000 volt isolation and finger
safe terminals. All modules are solid state so there are no moving parts to
ever wear out.
I/O modules are available in 4
color coded models:
- Black OAC modules
(Output, AC) perform just like a solid state relay. You provide a
dc or ac control signal, and the OAC module creates a 1-3 amp switched AC
output for 12-280Vac loads. A field replaceable 3 amp fuse is accessible
from the front.
- Red ODC modules provide a 1-3
amp switched DC output for 5-60Vdc loads. A 3 amp fuse is accessible
from the front.
- Yellow IAC modules accept
90-280 AC input signals and provide an isolated input to an automation
system. IAC modules are available as positive or negative logic (similar to
normally open vs normally closed).
- White IDC modules accept 4-28
DC input signals and provide an isolated input to an automation system.
IDC modules are available as positive or negative logic (similar to normally
open vs normally closed).
Examples of use include:
- PLC interface -- i/o modules
provide an easy terminal to wire to; up to 4-8 times greater isolation per
point for better human safety and better machine protection; and a low cost
replacement cost. (It is easier to replace a fuse in the I/O module, or a
complete i/o module, than it is to replace a multi point PLC output card and
then re-booting the PLC.)
- Process controller interface --
many controllers provide low power vdc logic outputs that can use i/o modules
to activate AC alarm lights, 1-3 amp solenoids, and other AC or DC
devices.
- Computer interface -- most
microprocessor based controllers can only sense or generate low level TTL (0/5
vdc) signals. The Power-io modules can sense, or switch, high level ac or dc
signals.
- Network interface -- there are
hundreds of DeviceNet, USB, ProfiBus, Ethernet, or remote I/O blocks that are
network connected and then generate multiple logic outputs. I/O modules (1-3
amps) or Power-IO "D" family (1-100 amps) turn those network I/O ports into
power I/O ports.
- Isolation -- whether your
application is a four point home automation system or a 4000 point factory
automation cell, the Power-IO isolation barrier ensures that your system is
protected from damage from external devices and from ground loops. Each point
is 4000 volt isolated from other points or from the PLC/PC control
system.
