SEA-520W

520W SeaI/O-520W Expansion Module Wi-Fi 802.11b/g Modbus TCP to 8 Isolated Inputs / 8 High-Current Form C Relay Outputs

Description

The Sea/O-520W provides a wireless network connection to eight optically isolated inputs and eight high-current Form C relay outputs. 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 60VDC. Form C relays can be wired for either normally open ornormally closed operation. The SeaI/O-520W is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-520W over Wi-Fi (802.11b and 802.11g) networks using industry standard Modbus TCP protocol or use the Sealevel SeaMAX APIsoftware libraries from your application program. Sealevel’s SeaMAX software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. Security features include WEP and the latest WPA-TKIP and WPA2-AES encryption standards.

The Sealevel Modbus Connect app for iOS allows you to access the registers, coils and discrete I/O of your Sealevel Modbus devices and is available on the App Store. Use the app to remotely access I/O in the field or for testing and troubleshooting during application development.

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.
