Introduction
The I-7005 module is used for measuring temperatures using a thermistor. The module supports a wide range of thermistors, including support for user-defined thermistor types, which can be added by specifying the Steinhart coefficients, if necessary, and features individual channel configuration, meaning that each of the eight input channels can be individually configured for different kinds of thermistor. In addition, the I-7005 also provides 6 Digital Output channels that can be used for alarm output. The inclusion of 3000 VDC intra-module isolation and 120 VDC overvoltage protection for the thermistors on the I-7005 ensures that the module operates at a higher reliability. The M-7005 supports both the Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7005.
