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

Inputs can range from 5-30V DC 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 250V AC and 100V DC. Form C relays can be wired for either normally open or normally closed operation.

The SeaI/O-520S is powered from your 9-30V DC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-520S using the Sealevel SeaMAX API software libraries or use any Modbus RTU compliant device. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using Windows and Linux.

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.

Impulse is a leading UK distributor of Sealevel products and can supply you the 520S along with a wide range of industrial computing and communication products.
