The SeaI/O-540M is an RS-485 Modbus RTU interface to 32 open-collector outputs. The open-collector outputs provide high current sinking over a large operating voltage.
Each open-collector output circuit includes a flyback diode for protection when interfacing highly inductive loads, such as DC motors. Outputs are grouped in eight-bit ports which share high and low voltage contacts via 3.5mm terminal blocks.
The SeaI/O-540M is powered from your 9-30V DC source, or select from a variety of Sealevel power supply options.
Communicate with the SeaI/O-540M 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 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.
