8 Channel RTD to Modbus RTU.
DAT10019
The DAT10019 Modbus RTU Converter is an 8-channel input module designed to acquire RTD and resistance signals and transmit them over a Modbus RTU or Modbus ASCII network. It operates as a slave device, making sensor data directly available to PLCs, SCADA systems, and other Modbus masters.
Configuration is simple using DIP switches, which allow the user to set the Modbus address, baud rate, parity, and communication mode (RTU or ASCII). The DAT10019 supports 2-wire RTD sensors only, due to terminal space limitations.
The device provides 1500 Vac galvanic isolation between inputs, outputs, and power supply, ensuring safe operation and noise immunity in industrial environments. It operates from a 10–30 VDC power supply.
