8.2 RTD Probe and Interface
8.2.1 Overview
The DPI 610E can be configured to display readings from the RTD-INTERFACE, which is a
remote adapter interface and the RTD-PROBE (or any other compatible probe). Temperature
measurements can be displayed as resistance or temperature units. The RTD-PROBE and
RTD-INTERFACE are available in both safe and hazardous area models. The RTD-PROBE is
fitted with a 15 cm (6”) class-A PT100 probe. The model names are as follows:.
The RTD-PROBE/RTD-INTERFACE connects to the DPI 610E with the supplied 2.9m (9.5 feet)
cable. The RTD-INTERFACE is supplied with a field-rewireable M12 connector to allow for
connection by User 2,3 or 4-wire RTDs.
8.2.2 Temperature Considerations
Careful consideration must be taken when using the RTD-INTERFACE and the
RTD-PROBE, or any specialist RTD probes, that the environment and process temperatures do
not exceed the specified limits for each RT component as detailed in the table below.

The capability of the RTD-INTERFACE
(resistance range) with a suitable extension
cable and suitable probe is 0 to 400
Ω
which
equates to -250ºC to +650ºC for a PT100 probe.
