The SeaI/O-530S is an RS-232 Modbus RTU interface module with 16 optically isolated inputs and 16 open-collector outputs, designed for industrial control systems..
The SeaI/O-530S offers 16 isolated digital inputs for safe interfacing with industrial equipment, alongside 16 open-collector outputs capable of sinking large currents, perfect for switching DC motors or other inductive loads. It uses the RS-232 Modbus RTU protocol, ensuring smooth integration with industrial control systems. You can use the Sealevel SeaMAX API or Modbus RTU-compliant devices for simple communication.
The device features convenient removable 3.5mm terminal blocks for easy wiring and supports a wide voltage range for both inputs and outputs. Powered by a 9-30VDC source, it’s highly adaptable for various environments and offers extended operating temperatures.
16 Optically Isolated Inputs – Protects your system from voltage spikes and ground loops. Rated for 5-30VDC.
16 Open-Collector Outputs – Ideal for driving DC motors and high-power devices. Provides high current sinking with protection for inductive loads.
RS-232 Modbus RTU – Seamless integration with Modbus RTU protocols.
Flexible I/O Network – Easily add additional modules for scalability.
