C-DIAS TEMPERATURE SENSING MODULE CAI 888 Wiring Guidelines The signals recorded by the analog modules are very small, as compared to the digital signals. To ensure error-free operation, a careful wiring method must be followed. • The 0 V connection of the excitation voltage must be connected with the 0 V assembly point over the shortest route possible.
