Modbus Register Map
This Modbus RTU expansion module integrates 16 digital inputs and 8 relay outputs, making it a cost-effective solution for industrial automation, building management, and energy monitoring applications.
Inputs support dry-contact devices such as switches, push buttons, and relays, while outputs are rated up to 220V/5A for driving alarms, solenoids, and other field devices. Built on a 32-bit ARM core processor, the module ensures stable performance, high-speed communication, and seamless integration with Modbus-based control systems.
Compact, reliable, and easy to configure, this module is suitable for OEMs, integrators, and engineers looking to expand digital I/O without adding a full PLC.
