Sealevel Digital I/O Solutions

I/O Ethernet digital I/O modules are cost-effective and allow remote monitoring of digital I/O from anywhere on your 10/100BaseT Ethernet network. I/O options include optically isolated inputs, Reed and Form C relays. Choose modules powered by your 9-30VDC source or the RJ45 connector with Power over Ethernet (802.3af) versions. eI/O modules easily mount on 35mm DIN Rail and communicate using Modbus TCP or Sealevel SeaMAX software.

USB digital I/O modules connect to any computer's USB port and offer choices including optically isolated inputs, Reed and Form C relays, and TTL interface to industry standard solid-state relay racks. Robust software drivers make implementation and troubleshooting easy.

Sealevel PCI Express digital I/O boards are designed for computers with X1 PCI Express slots and are compatible with any PCI Express slot. Digital I/O boards are currently available with optically isolated inputs and Reed relay outputs. Optically isolated inputs protect the PC from voltage spikes common to industrial environments while Reed relay outputs provide reliable, long-life switch closures suitable for low current applications.
 

Sealevel low profile PCI digital I/O boards meet the requirement for the MD1 low profile specification and feature Universal Bus (3.3V and 5V) for compatibility with both new and legacy computer systems. Low profile PCI digital I/O boards are available with optically isolated inputs and Reed relay outputs. For high-voltage requirements, a TTL version is available which provides convenient connections to industry-standard solid-state relay racks.

 

Designed to meet the core needs of PC/104 applications requiring high reliability, small size, and long-term availability, Sealevel PC/104 digital I/O modules offer easy installation and robust software support.

 

Sealevel Porthole footprint allows easy mounting in a Relio industrial computer or custom enclosure. These models provide a low I/O count solution and are available with optically isolated inputs, Reed or Form C relay and TTL outputs. The Porthole design is perfect for expanding industrial computing platforms using only an internal USB connection.

Sealevel is committed to offering long-term availability of all our products. We are proud to still offer legacy ISA digital I/O boards designed more than a decade ago.
