Thermocouple to Modbus TCP, Ethernet.
DAT8018
The DAT8018 is an advanced 8-channel isolated Thermocouple to Modbus TCP converter designed for industrial automation, process monitoring, and laboratory applications. Each channel can accept a wide variety of thermocouples, including J, K, R, S, B, E, T, and N types, as well as millivolt (mV) inputs up to 250 mV, making it highly versatile for temperature measurement and signal conversion.
The DAT8018 ensures reliable and safe operation by providing full electrical isolation between all inputs, Ethernet communication, and the power supply, rated up to 1500 VAC for 1 minute. This level of isolation protects both your equipment and personnel when working in harsh industrial environments.
Equipped with Ethernet 10/100BaseT communication, the DAT8018 enables seamless integration into Modbus TCP networks, allowing for efficient data acquisition, monitoring, and control with PLCs, SCADA systems, and industrial PCs. Its wide power supply tolerance from 10 to 30 Vdc ensures compatibility with a variety of power configurations in control panels or industrial racks.
Designed for easy installation, the DAT8018 is DIN Rail mountable, providing a compact and organized solution for industrial enclosures. Its 8-channel capability allows users to monitor multiple thermocouple or mV signals simultaneously, reducing the need for multiple converters and simplifying network architecture.
Overall, the DAT8018 is a reliable, high-performance solution for industrial temperature monitoring, providing precision, safety, and flexibility in a single device.
