In the field of industrial automation, EtherCAT temperature input modules are key devices for high-precision temperature measurement. Here is a detailed introduction to these modules:

Product Features

• High-Precision Temperature Measurement: Offers 4-channel inputs for both RTD and thermocouple sensors, supporting various sensor types, with a resolution of 0.1°C and an accuracy of ±1°C, ensuring accurate temperature measurement.
• Multiple Sensor Support:RTD: Supports PT100, PT200, PT500, PT1000, and Ni20 type RTDs.Thermocouple: Supports K, J, T, E, N, S, R, B, and C type thermocouples.
• Multiple Connection Methods: Supports 2-wire, 3-wire, and 4-wire connections, defaulting to 3-wire.
• High Reliability: Equipped with optocoupler isolation and an isolation voltage of AC 500V, ensuring stable signal transmission and reducing electromagnetic interference.
• LED Status Indicators: Each channel has an independent LED indicator light, facilitating on-site debugging and fault diagnosis. The LED lights have two states: flashing and off, indicating that the channel is detecting a temperature signal and no signal input, respectively.
• Plug-in Structure: Supports rail mounting, making installation and maintenance simple.
