New SeaI/O Digital I/O Solutions!

Sealevel recently announced two additions to the popular SeaI/O family of modular I/O products, each offering 96 channels of TTL digital I/O. Both products are designed for interfacing a variety of real-world I/O, including industry standard solid-state relay (SSR) racks. Ordering options allow control from a host device via Ethernet (Modbus/TCP), RS-485 (Modbus/RTU), USB, or RS-232.

Both the SeaI/O-462 and the SeaI/O-463 address the 96 channels of I/O as 12 eight-bit ports, each programmable as input or output. The SeaI/O-462 makes the I/O available via dual DB-78 female connectors. For easy connection to relay racks, Sealevel offers a six-foot cable that terminates each DB-78 to two industry standard 50-pin IDC connectors.

 

The SeaI/O-463 uses four internal 50-pin headers that connect to relay racks via standard ribbon cables. A metal strain relief bracket is included to secure the cables after installation.

Standard operating temperature range of SeaI/O modules is 0° C to 70° C and extended temperature range (-40° C to +85° C) is optional. SeaI/O prices start at $239 and product is available immediately from stock.

New Lower SeaI/O Prices!

Sealevel has announced new lower prices on all SeaI/O digital I/O products. SeaI/O modules are perfect for a wide variety of applications and environments including process control, data acquisition, broadcast automation, security, and facility management.

Multiple units of any I/O type can be easily daisy chained together using convenient RJ-45 pass-through connectors or screw terminals. This expansion capability enables a distributed network to be controlled with even a traditional point-to-point USB or RS-232 host connection. For easy software integration, application programs or 3rd party software can use the Sealevel SeaMAX library or industry standard Modbus protocol.

For complete information on SeaI/O please download the SeaI/O Brochure here (PDF).

Non-Standard Synchronous Protocols? - No Problem!

Standard protocols like HDLC/SDLC are easily supported by Sealevel Systems’ line of synchronous communication adapters using our SeaMAC v4 device driver. However, some applications require interfacing new equipment to an existing system that communicates with a proprietary protocol.

To assist customers with specialized requirements, Sealevel has partnered with system level software developers like Teligy. Teligy specializes in writing communications device drivers and is intimately familiar with Sealevel’s synchronous communications products.  Their technical team consists of industry veteran developers, each with many years experience in developing custom protocols and finding solutions to unique communications requirements.

While each non-standard protocol is unique, Sealevel Systems’ line of synchronous communication adapters provides a great deal of flexibility when combined with a custom or modified device driver. If your protocol is non-standard or if you are having difficulty finding a compatible communications solution for your application, please call Sealevel Systems and ask about custom solutions for the synchronous communications product line.
