Introduction
System Specifi cations
ET-7005/PET-7005 is used for measuring temperature by the thermistor. It supports many kinds of thermistors and features individual channel
configuration which means that eight of its input channels can individually be configured with different kind of thermistor and supports
user-defined types by specifying the Steinhart coefficients to add other thermistors, if necessary. Besides, ET-7005/PET-7005 also has
4-channel digital outputs for alarm output with Short-circuit protection and overload protection. Adding 2500 V
