Modbus Digital I/O Modules

Modbus Digital Input Output Modules.

The Datexel DAT3100 series offers a range of Modbus Digital Input/Output modules designed for industrial data acquisition and control. These compact and reliable modules accept digital voltage inputs and provide outputs via relays, NPN, or PNP transistors.

Communication is supported over RS485 or RS232 using Modbus RTU or ASCII protocols, making the DAT3100 series compatible with both legacy and modern systems. These modules are ideal for scalable installations, from small I/O expansions to large distributed systems.

When combined with DAT9000 Modbus controllers and DAT3000 analog I/O modules, the DAT3100 series becomes a smart and cost-effective solution for complete Modbus-based data acquisition networks.

A Modbus Digital I/O module allows digital signals to be read (input) or sent (output) using the Modbus protocol. These signals typically represent ON/OFF or HIGH/LOW states used in automation systems for switching, monitoring, or control.

The DAT3100 series supports a variety of digital outputs including SPST relay outputs, NPN open collector outputs, and PNP transistor outputs, offering flexible integration for different control requirements.

Yes, the DAT3100 series supports both RS485 and RS232 communication interfaces using Modbus RTU or Modbus ASCII protocol, making them suitable for new or legacy systems.

Yes, the DAT3100 digital modules can be combined with the DAT3000 analog modules and the DAT9000 series controllers to create a complete Modbus-based data acquisition and control system.
