Next Level I/O Expansion & Data Acquisition – The Relio R1 I/O Controller

May 1, 2018

Sealevel Systems, Inc. announces the newest member of the Relio™ family of industrial computers, the Relio R1 I/O Controller. Originally developed as a point-of-sale ticketing solution, the R1 I/O Controller is designed for harsh, industrial environments. With a solid-state, zero-maintenance, compact footprint this I/O controller is ideal for mobile, embedded control, test and measurement, and I/O intensive applications.

Expand the I/O capabilities of the I/O Controller by adding SeaI/O data acquisition modules. Host connectivity options include wireless, Ethernet, USB, RS-485 and RS-232 to meet a specific application. Each host SeaI/O module can support an additional 246 expansion modules for exponential I/O possibilities. Serial ports can be easily added using SeaI/O and SeaLINK USB serial adapters. Together the Relio R1 I/O Controller and SeaI/O modules create an incredibly robust remote I/O control and monitoring network.
