Micro Series & OCS I/O

Horner Micro Series

Our Micro OCS line of products introduces a series of fixed I/O controllers with exceptional performance and a streamlined ordering and pricing structure. These powerful and efficient controllers are well-suited to perform many of the same high-end applications as our popular XL series at the price point of an introductory component – value engineering hard at work.

OCS I/O: Highly Expandable & Flexible Remote I/O for OCS

Maybe You Only Need One More…

Sometimes you only need a little bit. Start with the CNX116 – which includes I/O right on the base. Meant as the perfect small amount of complementary I/O, the CNX116 gives you (2) Flexible Inputs (Digital or 12-bit Analog), (2) Digital Outputs, (1) 16-bit Universal Analog Input and (1) 12-bit Analog Output right onboard. Two inputs that can be used for either digital or analog signals, giving it up to 3 analog inputs without even needing another module.

…Or Maybe You Need A Lot

With expandability up to 7 modules per base and 16 bases per network, OCSI/O can handle almost any amount of I/O needs. It even includes a CsCAN In and CsCAN Out port to allow you to easily daisy-chain multiple bases without requiring a lot of custom wiring.

and Configuration Is a Breeze

Whether it’s a little or a lot, OCS-I/O configuration is meant to be simple and effortless. It’s configured using Cscape software, so when wired up, it can find the base and autopopulate all installed modules automatically. From there you may only need to tweak a couple of configurations for the base or modules to be ready to go. Cscape also calculates the I/O power usage for you automatically, so you’ll never overload an I/O base.
