Expansion Remote I/O Modules

Expansion I/O extends the channel count of various Sealevel I/O, including digital I/O, analog I/O, TTL I/O, relays and open collectors whilst lowering the overall cost.

We have been supplying remote I/O modules for over 20 years. Our comprehensive range includes Ethernet, USB, serial, wireless and fieldbus I/O modules offering analog, digital and relay acquisition and control.
