2.5 Detector Personality Modules
2.5.1 DPM Types
Three DPM types are used for temperature control and detector interface:
● Intrinsically Safe Thermal Conductivity DPM
● Base3DPM
● Temperature Control Personality Module (TC-PM)
The interfaces available for each are shown in the table below.

2.5.2 Base3 Detector Personality Module (DPM)
Output signals from any of the detectors connect to each associated Detector Personality
Module (DPM) input. The transfer of detector data is based on the database method. The DPM
digitizes the signal and then passes the data to the SYSCON via an I
2
C port. Results can then
be viewed on the Color Touchscreen or the workstation.
The method is the part of the application that contains the parameters for controlling the
hardware used by one cycle clock. It provides peak areas and component concentrations and
includes all cycle clock timed events. There is one cycle clock per method.
