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.
