Each DI-8B35 module isolates, filters, amplifies, and linearizes a www.DataSheet4U.com single channel of temperature input from an RTD and provides an analog voltage output. RTD excitation is provided from the module using a precision current source. Excitation current does not flow in the input signal leads, which allows RTD mea...
