Product Manual Excerpt

The RTD module receives and stores digitally converted analog data from RTD units or other resistance inputs such as potentiometers into its image table for retrieval by all fixed and modular SLC 500 processors. An RTD module consists of a temperature-sensing element connected by two, three, or four wires that provide input to the RTD module. The module supports connections from any combination of up to four RTD units of various types (for example: platinum, nickel, copper, or nickel-iron) or other resistance inputs. The RTD module supplies a small current to each RTD unit connected to the module inputs (up to 4 input channels). The module provides on-board scaling and converts RTD unit input to temperature (°C, °F) or reports resistance input in ohms. Each input channel is individually configurable for a specific input device. Broken sensor detection (open- or short-circuit) is provided for each input channel. In addition, the module provides indication if the input signal is out-of-range.
