Dewetron PAD-TH8-P 8-Channel Thermocouple and RTD Rear Plug-In Module

The Dewetron PAD-TH8-P is an 8-channel rear plug-in module for simultaneous thermocouple and RTD temperature measurement in industrial, automotive, and aerospace test environments. It delivers isolated channels with cold junction compensation on thermocouple inputs and configurable RTD excitation, integrating directly into Dewetron data acquisition systems via RS-485 or CAN protocols. The module supports eight thermocouple types and three RTD standards, making it suitable for multi-sensor thermal monitoring across diverse temperature ranges and sensor configurations.

## Technical Specifications
