RS-485 Modbus RTU Interface to 8 Isolated Inputs /

8 High-Current Form C Relay Outputs

Control and monitor 8 optically isolated inputs and 8 (SPDT) high-current Form C relay outputs with the SeaI/O-520M. Inputs can

range from 5-30VDC and optical isolation protects the computer and other sensitive equipment from voltage transients and ground

loops that are common in industrial environments. The high-current Form C relays can switch up to 6A loads at 250VAC and up to 5A

at 30VDC. Form C relays can be wired for either normally open or normally closed operation. The SeaI/O-520M is powered from your

9-30VDC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-520M using industry-standard Modbus RTU protocol or use the Sealevel SeaMAX API software

libraries from your application program. Sealevel’s SeaMAX software drivers and utilities make installation and operation easy using

Microsoft Windows and Linux operating systems.

Expand your I/O network with SeaI/O N-series products. SeaI/O modules are available with Reed and Form C relays, optically

isolated inputs, TTL interfaces, A/D and D/A functionality. Up to 246 additional expansion modules can be added using convenient

pass-through connectors.

Get a jump start on your digital I/O development with The Digital I/O Handbook that will provide helpful information that you will use

again and again. Check out Chapter 1 for an overview of logic principles.
