PROBLEM: Creating Flexible Data Acquisition & Control Networks

SOLUTION: Sealevel’s SeaI/O Modules

Create flexible, remote I/O installations anywhere on your network with Ethernet and Wireless data acquisition modules,
or choose I/O modules that connect directly to the host using USB, RS-485 or RS-232 interfaces. Applications include:

I/O OPTIONS

Optically Isolated Inputs, Reed Relay Outputs
Form C Relay Outputs, Open-Collector Outputs
TTL Interfaces, Analog A/D & D/A
Dry Contact Inputs

CONNECTIVITY

Ethernet
Wi-Fi
USB
RS-485
RS-232

FEATURES

Supports Industry Standard Modbus TCP & RTU Protocols
Status Indicator LEDs for Communication, Fault, and Status
Field Removable Terminal Block Connectors (most models)
Daisy Chain up to 247 Modules
9-30VDC Power Input
Power Input via Terminal Block or DC Jack
Rugged Metal Enclosure
Din Rail or Table Mount
Extended Temperature Range Available (-40°C to +85°C)
Powerful software conﬁguration & diagnostic tools
Address selectable via software or switch
Selectable RS-485 line conditioning

SeaI/O modules provide powerful digital, analog, and serial expansion to any computer. Connect to the host via wireless, Ethernet, USB, RS-485, or RS-232 to add the functionality required for your particular application.

Multiple units can be daisy chained using convenient pass-through connectors to create a versatile distributed control and monitoring network. For ease of installation, multiple modules can be combined in a local stack or separated up to 4000 feet using the RS-485 Modbus RTU expansion interface. Choose from a variety of I/O configurations, each designed for maximum flexibility and easy field wiring. For quick software implementation, application programs or third-party software can use Sealevel’s SeaMAX libraries or industry-standard Modbus protocol.
