Industrial Modbus Digital Output Module – 32-Channel NPN Transistor Outputs
High-density industrial digital output module featuring 32 NPN transistor outputs with RS485 Modbus RTU communication, ideal for PLC and automation control applications.
This industrial Modbus digital output module provides 32 independent transistor (NPN) digital output channels, designed for fast, reliable control of external devices such as relays, solenoids, indicators, alarms, contactors (via interposing relays), and other low-power loads.
Using RS485 serial communication and the widely supported Modbus RTU protocol, the module integrates seamlessly with PLCs, HMIs, SCADA systems, industrial PCs, and IoT gateways. Transistor outputs enable high-speed switching, long operational life, and silent operation compared to mechanical relays.
The compact, industrial-grade design makes this module well suited for control cabinets, distributed I/O systems, and automation retrofits where high output density and reliability are required.
