Some modules in the SmartBlock I/O Series, from Horner Automation, are considered "mature" and will soon no longer be in production. We recommend considering the Horner OCS-I/O for new users and new applications in need of remote Input / Output.
SmartBlock I/O from Horner Automation
SmartBlock is designed to complement the extremely popular SmartStix Digital I/O Series. These two I/O series can expand the I/O capacity of just about any Horner Automation controller by merely a few points - or potentially a few thousand. Additionally, SmartBlock easily configures using Horner Cscape software and can be quickly implemented into an existing or new Horner OCS controller. Using CsCAN communications, SmartBlock I/O provides easy configuration and network expansion.
- wide variety of digital, analog, and mixed I/O options
- easy-to-read, separate input / output connectors
- LED indicator lights for each I/O point, power, in addition to network status
- include a 5-pin double CsCAN plug as well as Removable Field Wiring Terminals
- DIN-rail mountable, in fully enclosed plastic housing
Isolated & Highly Accurate Analog I/O

The SmartBlock modules can be fully isolated and are highly accurate with 16-bit resolutions on most models. RTD and THM Analog models offer a .5˚C accuracy margin with a 0.1˚C resolution. Overall, this makes the SmartBlock a perfect match for applications that need precise, accurate data, noise immunity, as well as data integrity.
Applications of the SmartBlock from Horner Automation
- manufacturing, for example: custom OEM products, food processing, automotive parts, etc.
- power management & back-up generation
- semiconductor applications
- mobile and packaging machinery
- municipal water treatment in addition to HVAC and environmental control
- compressor, pump, motion, and also distributed conveyor control
Switch to Horner OCS-I/O
The Horner OCS-I/O is a flexible, highly expandable Input/Output system that can be applied as a local expansion I/O or as remote I/O distributed over hundreds of meters. With expandability up to 7 modules per base as well as 16 bases per network, OCS-I/O can handle almost every Input / Output need. Additionally, it includes a CsCAN In and CsCAN Out port, which allows users to easily daisy-chain multiple bases without requiring extraneous custom wiring.
- local expansion I/O or remote I/O up to 500 meters away
- expandable with up to 7 modules per base and 16 bases per network
- screw-type terminals standard; spring-clamp style optional
- nine I/O modules to choose from, all with different I/O capabilities
- compact design to allow easy installation into existing control systems
- configures with easy-to-use, free Cscape programming software
