8-Channel Thermocouple Simulator
The DNA-STP-TC-378 is sold separately from the DNx-TC-378 but is recommended for most applications as it both simplifies wiring and provides the requisite cold-junction compensation. The DNA-STP-TC-37 provides cold junction compensation with three ADT 7420 temperature sensors mounted on the board. If the DNA-STP-TC-37 is not used with the DNx-TC-378, care should be taken to account for the cold junction error created where the DNx-TC-378 outputs are connected to the system’s thermocouple inputs.
Note that for customer convenience, the DNA-STP-TC-37 provides both screw terminals as well as a second DB37 connector that passes signals through to the DNA-TC-378 board. Both the screw terminals and pass-through connector may be use concurrently but only one should be used for connection to each channel.
