Can the millivolt signal from a thermocouple be directly connected to a DCS card?
DCS system I/O cards come in various types. For AI signals, they can accept standard 4~20mA or 1~5V, as well as RTD or thermocouple signals; however, the type of temperature sensing element must be specified during configuration.
1. Install the transmitter directly on-site, outputting a standard 4-20mA signal.
The 2DCS can have a dedicated card unit for receiving thermocouple millivolt-level signals.
