4 Channel Thermocouple to Modbus RTU
DAT10016
The DAT10016 Modbus RTU Converter is a 4-channel module designed to acquire signals from thermocouples and millivolt sources and transmit them over a Modbus RTU or Modbus ASCII network. It provides direct integration with PLCs, SCADA systems, and other Modbus master devices.
The DAT10016 supports a wide range of thermocouple types, including K, J, R, S, B, E, T, and N. For millivolt inputs, it accepts ranges of ±50 mV, ±100 mV, and ±250 mV, making it versatile for both sensor and low-level voltage signal acquisition.
The device provides 1500 Vac galvanic isolation between input, output, and power supply, ensuring safe operation in industrial environments. It also includes reverse power protection on the supply input, safeguarding the module from wiring errors.
