Since 1986, Sealevel Systems has manufactured I/O products to serve the customers serial and digital interface requirements. Currently offering over 200 standard products, Sealevel offers high reliability and a commitment to customer satisfaction that is demonstrated by their ISO 9001:2000 Registration and the Lifetime Warranty that is standard with all Sealevel manufactured I/O products.

Serial Performance You Can Trust

Sealevels serial products designed using the XR16C850 UART provide 128-byte FIFO, 16 times larger than boards designed with 16C550 parts commonly found on other serial products. This capability allows error free operation even in high-speed applications regardless of the operating system.

The RS-232/422/485 multi-interface Capabilities afford the user maximum flexibility. Choose RS-422 mode for long distance communication up to 4000 feet where noisy immunity and high data integrity are essential. Or, select RS-485 and capture data from multiple peripherals in a RS-485 multi-drop network. The onboard auto-enable hardware automatically handles the RS-485 driver enable allowing the RS-485 ports to be treated as standard serial ports by the operating system. This allows the standard COM driver to be utilized for RS-485 communications.

Digital I/O Solutions

Whether your application calls for TTL interface to solid-state relays or can use our industrial I/O products offering relay output and optically isolated input, Sealevel can provide the digital I/O solution you need. The wide range of accessories, including terminal blocks and cabling, simplify the installation process.
